Tenso-Deformational Analysis Under Compression Of Brick Low Walls Using Numerical Modeling Techniques

Abstract

The compressive strength of masonry is determined by carrying out laboratory tests on prisms and wallets or through empirical formulations. Computational development has allowed the use of numerical models based on the Finite Element Method as an economically superior alternative for determining this property. In the present work, a computational model is obtained, calibrated and validated from the experimental results of Thamboo in 2019 for the study of brick masonry wallets, using the ABAQUS software. The invariants of the modeling process are described: geometry, materials, boundary conditions and loads. The stress-strain analysis of the results derived from the computational simulation is carried out, where the vertical and transverse stresses, plastic deformations and displacements are presented. Results are provided that correctly reproduce the structural behaviour and failure mode of the brick wall. This failure mode is characterized by vertical cracks parallel to the loading direction on the front and side faces of the samples, originating at the brick-mortar interface and propagating through the bricks.
