Abstract

Research and analysis on the walls of masonry structure houses in a certain area of north of Guangxi. The house walls are divided into three types: pure walls, walls with windows and walls with doors, and use ABAQUS to design the corresponding wall models, Adopt the horizontal periodic reciprocating load of different magnitudes to calculate the mechanical performance of the wall, and study the stress change characteristics and crack development law of the wall. The results show that: (a) Under load, the stress concentration of the wall is greatly affected by the hole. The larger the hole, the more obvious the stress concentration. (b) Under the load, the cracks change with the holes in the wall, and the cracks in the non-porous wall show a straight shape. As the wall openings appear and become larger, the cracks gradually change from a straight shape to an X shape, and then It becomes the law of V-shaped and inverted V-shaped.
