波纹钢板剪力墙抗侧性能研究

Research on lateral performance of corrugated steel shear wall

箱式模块化钢结构在数据机房工程中广泛运用。由于箱体要适合海上运输条件,箱体多采用波纹竖放形式。箱体结构在楼面竖向荷载作用下会产生竖向变形,进而影响波纹钢板墙的抗侧性能,造成抗侧刚度和抗震承载力退化现象。本文主要研究工作与成果如下:1)用ABAQUS软件建立波纹钢板剪力墙模型,分析未考虑竖向荷载作用时钢板墙的抗震性能,与规范公式进行对比。2)考虑部分竖向变形,分析波纹钢板剪力墙抗侧刚度与抗剪承载力的退化程度。

Modular steel constructions are widely used in data centers.Due to the need of sea transportation,corrugated steel shear walls are often placed vertically.Structure members occur vertical deformation under floor load.In addition,lateral performance of corrugated steel shear wall is decreaced by the reduce of lateral stiffness and seismic bearing capacity.
