Resistência à compressão de unidades e elementos de alvenaria estrutural cerâmica em protótipo e modelo reduzido produzido em laboratório

Abstract

Due to the great advantages that have been developed for a better understanding of the complex behavior of masonry structures, the methodology of using small-scale direct modeling has increased. This fact allowed a better identification of masonry’s structural behavior and also improved the experimental observation of the analytical processes adopted in the execution of structural projects. The prohibitive cost of full-scale testing has been taken into account. The study of reduced physical modeling in structural masonry through direct models brings simplifications to the tests procedures, allowing the study of more complex structural elements or even the analysis of the structures as a whole. This work studies also the behavior of units, prisms and wallettes, constructed with structural clay blocks at full and one-fifth scale specimens, in order to evaluate compressive and shear strengths as well as the relationship between prototypes and models. Due to the great advantages for a better understanding of the complex behavior of masonry structures, the methodology of using small-scale direct modeling has increased. The prohibitive cost of fullscale testing has been taken into account. In this work, axial and diagonal compression tests on clay blocks, prisms and wallettes are performed at full and one-fifth scale specimens, in order to obtain compressive and shear strengths.
