Desenvolvimento de código computacional para auxílio na análise de decisão sobre o tipo de estrutura: aço, madeira ou concreto armado

Abstract

Concrete is a material widely used in construction, due to its advantages of easily molding and structural features, but it has disadvantages linked to the weight of the constructions and the difficulty in realizing reform. In this sense, it is necessary the knowledge about the properties of other building materials, such as steel and wood, which performances can be compared in financial and structural terms with concrete. In this work, the main was compare the sizing, using the three materials mentioned, from the development of a software and adoption the Visual Basic programming language. The results obtained by the program were validated and this proved to be a viable sizing tool and could therefore be used for desired analysis. The study was made from the adoption of fixed calculation parameters for the three materials, with variation only of beam length and its height for concrete sections, defined from beam lenght. At the end, for small spans, it was not almost found important differences between three materials, until 5 meters, even though steel beams has shown better results. Between 6 and 8 meters it could be seen variability between three materials. After that, concrete beams seems to be more advantageous, only about cost parameter, because steel beams seems to be more advantageous about height and weight parameter. But the analysis made considered isolated parameters and studies concerning the execution times of buildings, cost of integrated construction systems , maintenance of materials, resistant properties, etc., must be developed, to achieve the best parameter and adoption the construction system, that fits the requirements of each construction.
