Nonlinear Dynamic Finite Analysis of BFRP-Strengthened Masonry Structure Based on ABAQUS

Abstract:

The externally bonded FRP is an effective strengthening technique, which is mainly verified through laboratory tests. In this paper, numerical analysis models were established in ABAQUS respectively based on an experimental scaled three-story confined masonry structures before and after strengthened with BFRP. Then dynamical analysis considering material nonlinearity, geometric nonlinearity and contact nonlinearity was carried out on these two models. Here, representative volume element method was used to simplify the simulation of masonry. Besides, concrete damage plasticity model was adopted to simulate the structural damage and failure process. The reliability and accuracy of nonlinear dynamic finite analysis were validated by comparing the numerical simulation results and experimental results in terms of dynamic property, displacement and acceleration response and the maximum base shear.
