Análise numérica e experimental do comportamento da alvenaria estrutural submetida à compressão diagonal

Abstract

The work leads to theoretical and experimental study on hollow clay block structural masonry walls, focusing on the shear strength. Firstly, some fundamental related topics are summarized, for instance: masonry components (block and mortar), prescriptions of some codes, results of the Young s modulus of hollow clay block and mortars, adopted by researchers in Brazil, and numerical procedures for modeling the walls, to be used in the subsequent analysis done by finite elements. A comparison among the obtained experimental results of tested walls with filled and unfilled head joints is made. Finally, walls in the two situations described are numerically modeled mainly to determine the regions that present larger stress concentrations, in order to identify the areas with larger possibilities of presenting cracks and even the collapse of the masonry for the studied action
