Numerical Simulation of Seismic Performance of Brick Walls Reinforced by High Ductility Concrete Strip Method
To improve the seismic performance of brick walls and ensure their safety,a numerical simulation method for strengthening the seismic performance of brick walls using high ductility concrete strip method is proposed.Specimens were prepared using AAC blocks,steel bars and concrete;Select materials such as fly ash,cement,sand,and PVA fibers to prepare high ductility concrete,and reinforce brick wall specimens with horizontal,vertical,and intersecting strips.Simulate the seismic performance of reinforced and unreinforced specimens using finite element software.The results show that the reinforced specimens have good seismic performance,with a load range of 305.3～-302.7 kN;Strip reinforcement can significantly delay the stiffness degradation of brick walls,with the highest cracking load and peak load reaching 419.2 and 511.06 kN,respectively.
