Flujo laminar: el cementerio de Igualada y los procesos elásticos en la arquitectura de Enric Miralles y Carme Pinós

La tesis Flujo Laminar, El cementerio de Igualada y los procesos elásticos en la arquitectura de Enric Miralles y Carme Pinós analiza la metodología que utilizan y desarrollan los arquitectos Miralles y Pinós en el proyecto del cementerio de Igualada. Enric Miralles y Carme Pinós comienzan a trabajar juntos en 1983, separándose siete años después. La producción arquitectónica que generan durante este periodo ha sido valorada y considerada por la crítica como una de las de mayor calidad en el último cuarto del siglo XX. Respecto a esta etapa de colaboración existen artículos dispersos que analizan de manera aislada algunos aspectos de sus proyectos. Sin embargo, no se han realizado estudios que analicen su metodología proyectual, sus herramientas, sus estrategias y sus diferentes conexiones y referencias. Tampoco se han analizado hasta el momento, cómo son sus procesos proyectuales, sus tiempos y sus objetivos. En este sentido, el proyecto del cementerio de Igualada será clave en la trayectoria del equipo. El tiempo extenso empleado en el proceso y la singularidad de la obra, además de otros factores del propio imaginario de Miralles y Pinós, marcarán a este proyecto como un punto de inflexión en su trabajo. La investigación plantea, en primer lugar, la descripción del contexto en el cual se comienzan a desarrollar los proyectos iniciales de Miralles y Pinós, además de los antecedentes que generarán la propuesta para el cementerio de Igualada. Seguidamente, se describen y analizan los apoyos y las referencias que los arquitectos utilizan en este proyecto, tanto las vinculadas a la cultura local como las atrapadas desde el imaginario universal. Por otro lado, el bloque central de la investigación aporta doce herramientas que construyen la metodología proyectual de Miralles y Pinós. Esta contribución se ha realizado desde el análisis y el cruce de los documentos originales del proyecto de Igualada y los escritos existentes de los arquitectos. Las herramientas aportadas son: deslizar, desplazar, repetir, enterrar, constreñir, oscilar, estirar, desenredar, desviar, rehacer, hendir y fluir. Todas ellas se describen, analizan e interpretan desde setenta y dos documentos esenciales extraídos del proceso de Igualada. Un último capítulo de conclusiones, define lo que se presenta en la investigación como una metodología propia de Enric Miralles y Carme Pinós, denominada procesos elásticos, en el que se describen sus cualidades y sus tiempos, a la vez que se presenta también una táctica empleada en el proyecto de Igualada denominada flujo laminar. ABSTRACT The thesis Laminar Flow, the Igualada cemetery and the elastic processes in the architecture of Enric Miralles and Carme Pinós analyses the methodology that the architects Miralles and Pinós used in the project for the Igualada cemetery park. Enric Miralles and Carme Pinós began to work together in 1983, and went their different ways seven years later. The architectural production they generated during that period has been valued and considered by critics to be among the greatest quality of production in the final quarter of the twentieth century. There is a scattering of articles about this period which give an independent analysis of some features of their products. However, there are no studies which analyse their project design methodology, their tools, their strategies and their different connections and references. Neither has there been analysis to date of the nature of their project design processes, nor of their times and their aims. Within this context, the Igualada cemetery project was key in the path to be trodden by the team. The great length of time used on the process and the singularity of the work, alongside other factors from Miralles and Pinós's personal imaginarium, were to mark this project as a turning point in their work. This research sets out, first of all, to describe the context in which the early projects by Miralles and Pinós began to be developed, as well as the background to the generation of their proposal for the Igualada cemetery. There follows a description and analysis of the resources and of the references that the architects used in this project, both those linked to local culture and those picked from the universal imaginarium. Furthermore, the central block of the research identifies twelve tools which make up Miralles and Pinós's project design methodology. This contribution has been performed on the basis of analysis and comparison of the original Igualada project documents and of writings extant by the architects. The tools identified are: slide, shift, repeat, bury, constrain, oscillate, stretch, untangle, divert, redo, groove and flow. They are all described, analysed and interpreted on the basis of seventy-two essential documents extracted from the Igualada process. A final chapter of conclusions defines what is presented in the research as a methodology which is specific to Enric Miralles and Carme Pinós, denominated elastic processes, describing their qualities and their times, along with the presentation of a tactic used in the Igualada project which is denominated laminar flow.

La planta Miralles: representación y pensamiento en la arquitectura de Enric Miralles

Resulta imposible disociar la evolución de la arquitectura de Enric Miralles de lo que fue el desarrollo de un sistema de representación propio. Partiendo de una posición heredada de su formación en la Escuela de Arquitectura de Barcelona y de su práctica en el estudio Viaplana-Piñón, donde adquiere el gusto por la precisión en el dibujo técnico, la delineación sobre papel vegetal o el grafismo constituido exclusivamente a base de líneas del mismo grosor, Miralles pronto evoluciona hacia un método caracterizado por un personal uso del sistema diédrico, vinculado a una concepción fragmentaria de la planta de arquitectura y del espacio mismo. Miralles proyectará por fragmentos de planta, asignándoles una geometría característica para diferenciarlos entre sí y desarrollar su espacialidad y sección con cierta autonomía, a través de planos y maquetas independientes. Gran parte de la arquitectura que elabora con Carme Pinós, en solitario o con Benedetta Tagliabue, estará compuesta por colecciones de piezas heterogéneas herederas de los fragmentos de la planta original, que encajan entre sí no en base a esquemas clásicos de integración subordinada o jerárquica, sino a través de posiciones relativas de yuxtaposición o superposición, caracterizadas por una ausencia de compacidad en la solución de conjunto. Este sistema de representación se apoya por tanto en la geometría como mecanismo de diferenciación por piezas, se basa en la fragmentación del diédrico desde la fragmentación de la planta, y en la falta de compacidad como soporte de pensamiento separativo. Un sistema que se define como “planta Miralles”, término que incluye todas las técnicas de representación empleadas por el arquitecto, desde planos a maquetas, pero que enfatiza la importancia estratégica de la planta como origen y guía del proyecto de arquitectura. La tesis se estructura en los tres primeros capítulos como un corolario de las categorías enunciadas, explicando, en orden cronológico a través de los proyectos, la evolución de la geometría, la utilización del diédrico, y el impacto de la falta de compacidad en la obra construida. Mientras que estos capítulos son globales, se refieren a la trayectoria de este método en su totalidad, el cuarto y último es un estudio de detalle de su aplicación en un proyecto particular, el Ayuntamiento de Utrecht, a través de los dibujos originales de Miralles. Tanto en la explicación global como en el estudio de detalle de este sistema de representación, la tesis pone de manifiesto su instrumentalidad en el pensamiento de esta arquitectura, argumentando que ésta no podría haber sido desarrollada sin la existencia del mismo. La relación entre representación y pensamiento es por tanto un tema capital para explicar esta obra. No obstante, hasta la fecha, las referencias al mismo en la bibliografía disponible no han pasado de ser una colección de opiniones dispersas, incapaces de construir por sí mismas un cuerpo estructurado y coherente de conocimiento. Se ha insistido sobremanera en el análisis y contextualización de los proyectos individuales, y poco en el estudio de la técnica proyectual utilizada para pensarlos y llevarlos a cabo. En definitiva, se han priorizado los resultados frente a los procesos creativos, existiendo por tanto un inexplicable vacío teórico respecto a un tema de gran importancia. Este vacío es el marco donde se inserta la necesidad de esta tesis doctoral. La investigación que aquí se presenta explica el origen y evolución del sistema de representación de Enric Miralles, desde su etapa como estudiante en la Escuela de Arquitectura de Barcelona hasta los últimos proyectos que elabora con Benedetta Tagliabue, así como el estudio de sus consecuencias en la obra construida. Termina concluyendo que su desarrollo es paralelo al de la arquitectura de Miralles, poniendo de manifiesto su vinculación y mutua interdependencia. ABSTRACT It is impossible to dissociate the evolution of the architecture of Enric Miralles from the development of his own system of representation. Starting from a position inherited from his training at the Barcelona School of Architecture and his practice at the office of Viaplana-Piñón, where he acquires a liking for precision in drafting and a graphic style based exclusively on lines of the same thickness, Miralles soon moves into a method defined by a customized use of the dihedral system, connected to a fragmented conception of the floorplan and space itself. Breaking up the floorplan into multiple fragments, Miralles will design an architecture where each of them has a unique shape and geometry, developing their sections and spatial qualities with a certain degree of autonomy within the whole, through separate plans and models. Many of the projects he designs with Carme Pinós, individually or with Benedetta Tagliabue, will consist of collections of heterogeneous pieces, heirs of the original floorplan fragments, which do not fit together according to classical principles of subordinate or hierarchical integration, but based on relative positions of juxtaposition or superposition that lead to a lack of compactness in the overall scheme. This system of representation is thus based on the use of geometry as a way of differentiating architectural pieces, on the fragmentation of the dihedral system from the fragmentation of the floorplan, and on a lack of compactness as a device of separative thinking. This system is defined as “Miralles plan”, a term that includes all techniques of representation used by the architect, from plans to models, and that emphasizes the particular importance of the floorplan as the guiding force of the design process. The first three chapters of the thesis have been structured as a corollary of these categories, explaining, in chronological order through Miralles’ projects, the evolution of geometry, the customization of the dihedral system, and the impact of the lack of compactness on the built work. While these three chapters are global, for they refer to the overall evolution of this system, the fourth and last one is a case study of its application to a particular project, the Utrecht Town Hall, through Miralles’ original drawings. Both in the global and particular explanations of this system of representation, the thesis highlights its instrumentality in the process of thinking this architecture, arguing that it could not have been designed without its parallel development. The relationship between thinking and representation is therefore a key issue to explain this architecture. However, to date, existing references to it in the available literature have not evolved from a collection of scattered opinions, unable to build for themselves a structured and coherent body of knowledge. Great emphasis has been put on the critical contextualization of this architecture through the analysis of the projects themselves, but little on the study of the design technique used to think and carry them out. Results have been prioritized over creative processes, existing therefore an inexplicable theoretical void on an issue of great importance. This void is the conceptual framework where the need for this thesis is inserted. This research explains the origin and evolution of Enric Miralles’ system of representation, from his time as student at the Barcelona School of Architecture to the last projects he designed with Benedetta Tagliabue, as well as the study of its impact on the built work. It concludes that the development of this system runs parallel to that of the architecture it is used for, making it explicit its indissolubility and mutual interdependence.

A Mouthful of Pins : questioning constructionist therapy frameworks in theatre-making

A Mouthful of Pins constitutes the practical component (50 per cent) of a practice-led Master of Arts through the Creative Industries Faculty of Queensland University of Technology. This research reports on the attempt to create a constructionist/collaborative theatre-making process by incorporating postmodern constructs borrowed from the therapy room. The study asserts that, when applied with awareness, therapeutic frameworks can help members of the creative team . including the director, performers, writer, designers and technicians . to fulfil their artistic capacity, thereby enriching their process, their performance and their collaborative relationship with each other. For this to occur, it is imperative that the director/facilitator stay curious and aware of how they lead their creative team, with particular care around their use of language, as well as an increased awareness of the multiple stories (including the sometimes invisible social, historical, political, theatrical and leadership discourses) that surround and impact the artist.s process. This research is designed to assist students of theatre, as well as established professional practitioners, to find an alternative approach for collaboration that can result in longevity of practice, while at the same time embracing best practice for their outgoing creativity.

Studies on friction and formation of transfer layer when Al-4Mg alloy pins slid at various numbers of cycles on steel plates of different surface texture

In the present investigation, various kinds of textures, namely, unidirectional, 8-ground, and random were attained on the die surfaces. Roughness of the textures was varied using different grits of emery papers or polishing powders. Then pins made of Al-4Mg alloys were slid against steel plates at various numbers of cycles, namely 1, 2, 6, 10 and 20 under both dry and lubricated conditions using an inclined pin-on-plate sliding tester. The morphologies of the worn surfaces of the pins and the formation of transfer layer on the counter surfaces were observed using a scanning electron microscope. Surface roughness parameters of the plate were measured using an optical profilometer. It was observed that the coefficient of friction and formation of transfer layer during the first few cycles depend on the die surface textures under both dry and lubricated conditions. It was also observed that under lubricated condition, the coefficient of friction decreases with number of cycles for all kinds of textures. However, under dry condition, it ecreases for unidirectional and 8-ground surfaces while for random surfaces it increases with number of cycles

A comprehensive study of interference and clearance fit pins in large plates

Pin joints in structures are designed for interference, push or clearance fits. That is, the diameter of the pin is made greater than, equal to or less than the hole diameter. Consider an interference fit pin in a plate subjected to a continuously increasing in-plane load.

Recent studies on the behaviour of interference fit pins in composite plates

Composites are finding increasing application in many advanced engineering fields like aerospace, marine engineering, hightech sports equipment, etc., due to their high specific strength and/or specific stiffness values. The use of composite components in complex situations like airplane wing root or locations of concentrated load transfer is limited due to the lack of complete understanding of their behaviour in the region of joints. Joints are unavoidable in the design and manufacture of complex structures. Pin joints are one of the most commonly used methods of connection. In regions of high stresses like airplane wing root joints interference fit pins are used to increase its fatigue life and thereby increase the reliability of the whole structure. The present contribution is a study on the behaviour of the interference fit pin in a composite plate subjected to both pull and push type of loads. The interference fit pin exhibits partial contact/separation under the loads and the contact region is a non-linear function of the load magnitude. This non-linear behaviour is studied by adopting the inverse technique and some new results are presented in this paper.

Microfabrication and application of reservoir pins for liquid transfer in biotechnology

Microarraying involves laying down genetic elements onto a solid substrate for DNA analysis on a massively parallel scale. Microarrays are prepared using a pin-based robotic platform to transfer liquid samples from microtitre plates to an array pattern of dots of different liquids on the surface of glass slides where they dry to form spots diameter < 200 μm. This paper presents the design, materials selection, micromachining technology and performance of reservoir pins for microarraying. A conical pin is produced by (i) conventional machining of stainless steel or wet etching of tungsten wire, followed by (ii) micromachining with a focused laser to produce a microreservoir and a capillary channel structure leading from the tip. The pin has a flat end diameter < 100 μm from which a 500 μm long capillary channel < 15 μm wide leads up the pin to a reservoir. Scanning electron micrographs of the metal surface show roughness on the scale of 10 μm, but the pins nevertheless give consistent and reproducible spotting performance. The pin capacity is 80 nanolitres of fluid containing DNA, and at least 50 spots can be printed before replenishing the reservoir. A typical robot holds can hold up to 64 pins. This paper discusses the fabrication technology, the performance and spotting uniformity for reservoir pins, the possible limits to miniaturization of pins using this approach, and the future prospects for contact and non-contact arraying technology.
