Failure mode, deformability and strength of masonry walls
Mohamad, Gihad; Lourenço, Paulo B.; Rizzatti, Eduardo; Roman, Humberto R.; Nakanishi, Elizabete YukikoFor materials such as concrete, the understanding of the failure mode, deformability and strength of block masonry walls are important to simulate the behaviour of the assembly. Still now, there are difficulties on determine experimentally results of the interaction between the materials, as concrete block, mortar and the interface between vertical and bedding joint. Because of this, experimental tests of mason...
Stress-strain behavior of concrete block masonry prisms under compression
Mohamad, Gihad; Lourenço, Paulo B.; Roman, Humberto R.; Barbosa, C. S.; Rizzatti, EduardoThe aim of this work is to critically assess a stress-strain model using experimental masonry prisms constructed from different blocks and mortar. The following conclusion may be drawn from this work: mortar is mostly responsible for the non-linear behavior of masonry. The initial tangent modulus, obtained taking into account the compressive strength, provides a strongly non-linear relationship between elastici...
Poisson of bedding mortar under multi-axial stress conditions
Mohamad, Gihad; Lourenço, Paulo B.; Roman, Humberto R.; Rizzatti, Eduardo; Sartori, TatianeThe main goal of this work is the understanding of triaxial compression capacity of bedding mortar. It was observed by the experimental tests that the behavior of the stress and strain response is highly nonlinear and depends on the increase of lateral stress. In all studies presented here, the ultimate strength envelope of triaxial mortar can be represented by a linear function with similar angular coefficient...
Numerical simulation of concrete block masonry under compression
Mohamad, Gihad; Lourenço, Paulo B.; Roman, Humberto R.; Rizzatti, Eduardo; Sartori, TatianeThe main goal of this work is evaluate numerical model to reproduce the compression test of concrete block prisms, through a constitutive model of materials using the theory of plasticity and compare its results with experimental tests to preview the stress, strain and failure mode of the masonry. The post peak behavior of the material under tensile followed an exponential law and, under compression, a paraboli...
