Escadas de concreto armado : rotina computacional de dimensionamento

Abstract

Reinforced concrete structures are widely used in the construction world. In the past, due to lack of knowledge of the materials used and the difficulty of laboratory tests, many buildings were oversized. Not only is this a major cause of material waste, but it can also cause wear problems, either due to the excess reinforcement that prevents good concrete adhesion or even the excess weight of the structure. With the advancement of computational technology, several programs were created in order to improve the design process of reinforced concrete structures, generating the best results related to safety and material economy. Following this line, the present study aims to create a computational routine capable of dimensioning reinforced concrete structures that are reinforced transversely, longitudinally or have a slab in balance. In addition, the program aims to design structures that generate or lower possible materials expenditures, but that meet the norms in force during the development period of this study. The programming language used in this study is the Visual Basic for Applications language, which has its use directed to the Microsoft Excel software (sic). Through the analysis of the obtained results, it can be concluded that the computational routine created meets the objectives described in this research, being able to of dimensioning reinforced concrete structures that are reinforced transversely, longitudinally or have a slab in balance.
