伪波纹型交叉密肋平钢板组合剪力墙参数影响分析

Analysis of Influencing Factors of Composite Shear Wall with Pseudo Corrugated Cross-Ribbed Flat Steel Plate

结合波纹钢板剪力墙以及平钢板剪力墙的优点,提出一种伪波纹型交叉密肋平钢板组合剪力墙结构。利用有限元分析软件ABAQUS建立足尺模型进行数值模拟研究,并通过改变梯形加劲肋的间距、高度和顶部宽度研究其对结构抗震性能的影响。研究结果表明:减小梯形加劲肋的间距以及增大梯形加劲肋的高度都可以有效地提高结构的滞回性能以及承载能力,但是当加劲肋高度超过一定值后,结构的滞回性能提高不明显;增加加劲肋顶部宽度对增强结构的滞回性能效果不明显,但是在加载前期可以减缓结构刚度的退化,在加载后期会适当提高结构的承载能力。

To combine the advantages of corrugated and flat steel plate shear wall,a pseudo corrugated cross-ribbed flat steel plate composite shear wall structure is proposed.In this paper,a full-size model is built by using ABAQUS software,and the influence of the trapezoidal stiffener on the seismic performance of the structure is studied by changing the spacing,height and top width of trapezoidal stiffener.The research results show that reducing the spacing and increasing the height of trapezoidal stiffeners can effectively improve the hysteretic performance and load capacity of the structure.However,when the height of the stiffeners exceeds a certain limit,the hysteretic performance of the structure does not improve significantly.Increasing the top width of the stiffener has no obvious influence on the hysteretic performance of the structure,but it can slow down the degradation of the structural stiffness in the early stage of loading,and appropriately improve the bearing capacity of the structure in the last stage of loading.
