Análise de paredes de contraventamento de alvenaria estrutural de blocos de concreto considerando os efeitos da fissuração

Abstract

This research consists an analyze of structural masonry shear wall behavior considering the effects of the cracking in mortar joints taking into account the cracking effects. For this purpose, it was used the simplified Equivalent Bars Model, including link elements between the bars to simulate the cracking numerically. The analyzes were performed using the software SAP2000 and consisted in the modeling of some shear walls that was tested experimentally by outher reseacher. In a second step, we proceeded with the modeling of a real building with 19 floors, using the equivalent bar model with link elements and a hybrid model formed by joining the MBEq and the Three-dimensional Portico, based on Yagui model. The results indicated that the idealized computational modeling reproduced consistently the effects of cracking, properly simulating the nonlinear behavior of masonry.
