Desenvolvimento de programa computacional para dimensionamento de blocos de coroamento

Abstract

Reinforced concrete pile caps are structures used as a transition element in deep foundation solutions and act by transferring the actions from the pillar to a group of piles. Their dimensions vary fundamentally on the sols of the superstructure, such as compression effort due to its own weight and bending moments from eccentricities or wind action. The present work aims to develop a computational code that makes possible the dimensioning and detailing of reinforced concrete pile caps supported by up to four stakes. To do so, this software is developed in Visual Basic language and uses the Strut and ties models, result of extensive physical models tested by Blevót and Frémy in 1967. Named "BetaBloks", the developed application is intended to receive data from input variables provided by the user, perform calculations and expose a calculation report with information regarding the dimensioning of the element, as well as verification and possibility of selection of the most efficient reinforcement bars. Its development was not designed to create software capable of replacing established structural calculation programs, but rather to create a simple and intuitive application, able to assist students and engineers in the design and verification of pile caps
