Loading height on reinforced brick masonry wall's failure mode and seismic performance with finite element analysis method

摘要

Loading height is a key factor that affects brick masonry wall specimen's failure mode and seismic performance. To explore reinforced brick masonry wall's failure pattern and seismic performance in different loading height, reinforced brick masonry wall MARC finite element model with 1.44 aspect ratio is set up to analyze its failure mode and seismic performance at constant vertical stress and different loading height. Results are as follows: bending failure happens more easily at higher loading height and shear failure happens more easily at lower loading height; wall specimen shows better deformation ability, elastic and plastic energy dissipation capacity but lower ultimate bearing capacity at higher loading height.
