Software para el diseño de dados de pilotes en concreto reforzado aplicando el método puntal-tensor de acuerdo al código ACI 318S-19

Abstract

One of the most important parts of the construction of a building is the structural design, this is the analysis and study of each one of the structural components, classical methods of structural analysis are commonly used based in the hypothesis that the behavior belongs to a B-region (Bernoulli assumptions apply) , but there are some kind of elements called D-regions where these classical methods cannot be applied, because it represents a different behavior. Pile caps are one of these types of structures, these are deep and short members located in the foundation of the building supporting a column and transferring the loads to a group of piles, their geometric configuration causes a discontinuity in the stress distribution, which make them a D-region. There are many studies and methods for designing pile caps, one of these is the strut and tie model, because it gives accurate results considering the unusual stress distribution of this elements, it represents the paths of load as a 3D truss, where the compressive forces between the column and the piles are supported by the struts and the tensile forces between the piles are carried by the ties, which determined the reinforcement. The aim of this project is to create a software with Visual Basic 6.0 that makes easier the design of these elements based on the fundaments of the strut and tie method given in the ACI 318s-19 and let us make a comparison between this design and the classical design of pile caps, in order to do that is presented a theorical description of the method and the procedure to follow to design pile caps, a particular case of a pile cap is studied to make the comparison between methods and finally a description of the software and a user manual to guide the people through the software and all the tools it has.
