Metodologia construtiva de paredes diafragma

In the study line about contention, using Diaphragm Wall, revising the characteristics, vantages and constructive methods, following the application due to Terzaghi's theory. This work will be revising the advantages of the excavation equipments like the Clamshell and the Hydraulic Rolling Excavator, excavation techniques, and types of steel reinforcements, concreting, draining methodologies and comparison with other techniques. Also, will be revised a Study of Case, which by the application of two executive methodologies, will be possible to make a comparative analyses in a real construction situation.

Aplicação da teoria da confiabilidade em estacas escavadas de grande diâmetro para obtenção das superfícies resistentes de projeto

In this work, the author looks forward to develop a new method capable of incorporate the concepts of the Reliability Theory and Ruin Probability in Deep Foundations, in order to do a better quantification of the uncertainties, which is intrinsic in all geotechnical projects, meanly because we don't know all the properties of the materials that we work with. Using the methodologies of Decourt Quaresma and David Cabral, resistance surfaces have been developed utilizing the data achieved from the Standard Penetration Tests performed in the field of study, in conjecture with the loads defined in the executive project of the piles. The construction of resistance surfaces shows to be a very useful tool for decision making, no matter in which phase it is current on, projecting or execution. The surfaces were developed by Kriging (using the software Surfer® 12), making it easier to visualize the geotechnical profile of the field of study. Comparing the results, the conclusion was that a high safety factor doesn't mean higher security. It is fundamental to consider the loads and resistance of the piles in the whole field, carefully choosing the project methodology responsible to define the diameter and length of the piles

Previsão da capacidade de carga de estacas escavadas em solo arenoso da região de Araquari-SC

In Geotechnical engineering the foundation projects depend on the bearing capacity and the acceptable displacements. One of the possible ways to predict the bearing capacity of foundations is through semi-empirical statistical methods which correlate in-situ tests (SPT and CPT). The piles breaking loads are defined by the interpretation of the load x head displacement curve and the experimental data acquired through the load test. In this work it is studied the behavior of bored piles executed in the Araquari/SC region, comparing the bearing capacity values predicted by the methods DECOURT & QUARESMA MODIFICADO (1996), AOKI & VELLOSO MODIFICADO MONTEIRO (2000), MILITITISKY E ALVES (1985), DECOURT & QUARESMA (1978), MÉTODO DE AOKI & VELLOSO (1975) e PHILOPANNAT (1986), with the results of the load test, evaluating their differences and discussing parameters that have direct effects on the prediction

Avaliação das causas e consequências das patologias dos sistemas impermeabilizantes: um estudo de caso

This work aims to assess a case ofwaterproofing pathology, from the presentation of the pathological manifestations, thecharacterization and quantification of negotiationsproposals. With these data, graphs were elaborated with thepurpose ofemphasizing the cost increase from the time of intervention, to give an increase of 1,429.00 % inthe presented study. Also show the proportion of spending on finishes and waterproofing,demonstratingthe greatinfluence of the finishes in the composition of the treatment costs. Inthisstudy, it was foundthat these finishes made up89% of the total cost. In the bibliographic reference, presented to the active mechanisms, the characterization of waterproofing systems and the most common pathologies. It follows the importance of sealing to ensure integrity of a construction

Implementação de CADD nos cursos de graduação em engenharia mecânica

This study aims to demonstrate the importance of computer-aided design and drafting (CADD) software for mechanical engineers. In addition, evaluate the software: Inventor 2015, Creo 3.0 and Solid Edge ST8, developed by consolidate companies in the market. In order to accomplish those goals, software application and its advantages will be demonstrated for the industry and for the academia. The evaluation process consists in modeling two mechanical assemblies, in order to compare functional aspects among the software. At the end, it is concluded that the learning of CADD software is of great importance also is the basis for using Computer-aided Engineering (CAE) and Computer-Aided Manufacturing (CAM) tools. Furthermore, it is suggested that Inventor and Solid Edge are more likely to be used in the academia
