开洞率对波纹板墙的抗震性能影响分析

ANALYSIS OF THE OPENING RATE AFFECT THE SEISMIC PERFORMANCE OF CORRUGATED WALL

波纹板是一种屈曲性能好、抗侧刚度大、耗能性能强的新型抗侧力构件,具有广阔的发展前景。采用有限元软件ABAQUS模拟研究开洞率对集装箱组合房屋墙板的抗震性能的影响,并采用了控制位移的循环加载方式。研究发现,随着开洞率的增大波纹墙板的承载能力及抗震耗能能力均逐渐减小。

Corrugated plate is a new type of anti lateral force component with good buckling performance,large lateral stiffness and high energy dissipation,and has a broad development prospect.This paper uses finite element software ABAQUS to simulate the effect of the opening rate and seismic performance of container housing portfolio wallboard,cyclic loading method with control displacement was adopted.Study found,The bearing capacity and seismic energy dissipation capacity of the corrugated wall decrease gradually with the increasing of the hole rate.
