Dimensionamento de pilares em concreto armado

Abstract

The reinforced concrete columns design is introduced to civil engineering students as a sequence of calculations with the aim of obtaining coefficients that allow consultation of the Venturini abaci, and thus finding the reinforcement ratio. The general objective of this work is to produce a computational algorithm that allows the design of reinforced concrete columns in an automated manner. In this way, it can be used in academia as a study tool. Using the equations presented in the bibliography, together with considerations of current standards, a logical flow capable of introducing an algorithm that provides acceptable results was obtained. The method for finding the reinforcement ratio applied to the program is an iterative process called the bisecant method, different from that proposed in academia, which are abacuses. Consequently, there was a certain variation (0,2% a 3,5%) in the results compared with those presented in the available literature, however, in proportions that were irrelevant in proving the calculations.
