Plan de negocios construcción de edificio para uso habitacional en la ciudad de Bogotá

Con este trabajo, se pretende elaborar una evaluación a nivel de prefactibilidad administrativa, técnica y financiera de la construcción de un edificio, partiendo del modelo de compra de vivienda existente, su posterior demolición y construcción del proyecto. Para llevar a cabo la evaluación a nivel de prefactibilidad, se tienen en cuenta los objetivos: •Estructurar y evaluar la propuesta técnica, financiera y administrativa a nivel de prefactibilidad. •Determinar el tamaño adecuado del proyecto de acuerdo a los planes zonales y de ordenamiento territorial de la ciudad. •Identificación de las posibles formas de financiación del proyecto. •Identificación de los futuros compradores del producto final, diagnostico y perspectivas del sector. •Evaluar la mejor estrategia de mercadeo y venta del producto final, ya sea de forma directa o con un intermediario especializado.

Nature of vegetation and building morphology characteristics across a city: influence on shadow patterns and mean radiant temperatures in London

Vegetation and building morphology characteristics are investigated at 19 sites on a north-south LiDAR transect across the megacity of London. Local maxima of mean building height and building plan area density at the city centre are evident. Surprisingly, the mean vegetation height (zv3) is also found to be highest in the city centre. From the LiDAR data various morphological parameters are derived as well as shadow patterns. Continuous images of the effects of buildings and of buildings plus vegetationon sky view factor (Ψ) are derived. A general reduction of Ψ is found, indicating the importance of including vegetation when deriving Ψ in urban areas. The contribution of vegetation to the shadowing at ground level is higher during summer than in autumn. Using these 3D data the influence on urban climate and mean radiant temperature (T mrt ) is calculated with SOLWEIG. The results from these simulations highlight that vegetation can be most effective at reducing heat stress within dense urban environments in summer. The daytime average T mrt is found to be lowest in the densest urban environments due to shadowing; foremost from buildings but also from trees. It is clearly shown that this method could be used to quantify the influence of vegetation on T mrt within the urban environment. The results presented in this paper highlight a number of possible climate sensitive planning practices for urban areas at the local scale (i.e. 102- 5 × 103 m).

Optimum position of steel outrigger system for high rise composite buildings subjected to wind loads

The responses of composite buildings under wind loads clearly become more critical as the building becomes taller, less stiff and more lightweight. When the composite building increases in height, the stiffness of the structure becomes more important factor and introduction to belt truss and outrigger system is often used to provide sufficient lateral stiffness to the structure. Most of the research works to date is limited to reinforced concrete building with outrigger system of concrete structure, simple building plan layout, single height of a building, one direction wind and single level of outrigger arrangement. There is a scarcity in research works about the effective position of outrigger level on composite buildings under lateral wind loadings when the building plan layout, height and outrigger arrangement are varied. The aim of this paper is to determine the optimum location of steel belt and outrigger systems by using different arrangement of single and double level outrigger for different size, shape and height of composite building. In this study a comprehensive finite element modelling of composite building prototypes is carried out, with three different layouts (Rectangular, Octagonal and L shaped) and for three different storey (28, 42 and 57-storey). Models are analysed for dynamic cyclonic wind loads with various combination of steel belt and outrigger bracings. It is concluded that the effectiveness of the single and double level steel belt and outrigger bracing are varied based on their positions for different size, shape and height of composite building.

The Distribution and Adoption of the Byre-house (Longhouse) in Late Medieval Britain

It has long been recognized that the byre-house or longhouse, in which animals and humans lived in the same building and with direct contact, was a distinctive building plan. Earlier interpretations have seen it as a ubiquitous house type found throughout Britain, but gradually replaced by separate buildings for keeping animals and accommodating humans. More recent work has suggested that it was a regional variant of the common late medieval domestic plan. The use of this building type was restricted to parts of Wales, and northern and western areas of England. It is argued that the introduction of the byre-house occurs mainly in the thirteenth century as part of a wider trend to provide accommodation for livestock during the winter months. The byre-house was a one response to this need, and its adoption was not due to climatic or geographical factors. Instead, it is interpreted as reflecting localized cultural attitudes to the relationship between humans and animals.

Seismic Assessment of a Steel Braced Plan Mass Symmetric/Asymmetric Building Structure

This paper presents a seismic response investigation into a code designed concentrically braced frame structure that is subjected to but not designed for in-plan mass eccentricity. The structure has an accidental uneven distribution of mass in plan resulting in an increased torsional component of vibration. The level of inelasticity that key structural elements in plan mass asymmetric structures are subjected to is important when analysing their ability to sustain uneven seismic demands. In-plan mass asymmetry of moment resisting frame and shear wall type structures have received significant investigation, however, the plan asymmetric response of braced frame type structures is less well understood. A three-dimensional non-linear time history analysis (NLTHA) model is created to capture the torsional response of the plan mass asymmetric structure to quantify the additional ductility demand, interstorey drifts and floor rotations. Results show that the plan mass asymmetric structure performs well in terms of ductility demand, but poorly in terms of interstorey drifts and floor rotations when compared to the plan mass symmetric structure. New linear relationships are developed between the normalised ductility demand and normalised slenderness of the bracing on the sides of the plan mass symmetric/asymmetric structures that the mass is distributed towards and away from.

Floor plan and notes for proposed building with chapel and hall, [ca. 1799]

Possibly drawn and written in the hand of President Joseph Willard. The proposed building would house a chapel, halls, chambers for scholars, and was to be built on the site of the first Stoughton Hall which was torn down in 1781.
