Redistribuição de momentos fletores em estruturas aporticadas planas de concreto armado

Abstract

This report deals with the study of the facts that affect the stresses redistribution in plane frame of reinforced concrete. Two computer programs were developed in order to analyse the physical nonlinearity: one was based on the displacement method and the other on the force method. An evolutive approach of the methods to design the structure from the linear elastic state till the plastic was done. Comparison between experimental and numerical results and simullations studying the disposition and quantity of the armadure were done. The influence of this on the bending moments was studyed, as well.
