Numerical Solution for Masonry Wall Using General Static Step with ABAQUS/Standard

Abstract

Masonry construction, an archaic and versatile building technique, entails the assembly of varied or homogeneous components (including brick, concrete block, stone, etc.) bound by cohesive agents such as mortar. The purpose of this study was to authenticate the validity of an ABAQUS-based solution corresponding to the experimental model of masonry shear walls tested by Raijmakers and Vermeltfoort under in-plane loading, thereby substantiating a developed Finite Element (FE) model. Utilizing a general nonlinear static procedure, the ABAQUS finite element software was employed for scrutinizing a continuous (990×1000) mm brick wall, absent of any openings. Analysis of the unreinforced masonry (URM) wall, facilitated by the ABAQUS software, yielded results that closely mirrored those of the experimental model. This comparison serves to underscore the implications of the current modeling approach and the proposed wall properties on its response, thereby fostering an enhanced comprehension of the global in-plane behavior of unreinforced brick masonry walls.

“…S ABC +S CDA S OBF +S ODE (5) where 𝑆 𝐴𝐵𝐶 is the area of the curve ABC (Figure 20), wherein similar definitions were used for 𝑆 𝐶𝐷𝐴 , 𝑆 𝑂𝐵𝐹 , and 𝑆 𝑂𝐷𝐸 . Figure 20 shows the simplified hysteresis loop that consists of the lateral load versus the displacement.…”

“…This improvement in the structural integrity becomes more significant than the initial performance. Rehabilitation is the process of reparation and restoration of the performance and strength lost in the structures under varied situations [4][5][6][7]. In the repairing process, the structural members' quality are improved to meet the desired requirements.…”
