开不同位置方形洞口波纹钢板剪力墙抗侧性能

Lateral Resistance of Corrugated Steel Shear Walls with Square Openings at Different Locations

本文以开不同位置方形洞口波纹钢板剪力墙为研究对象,利用大型通用分析软件ABAQUS通过非线性推覆分析研究了12种不同的开洞位置下的钢板剪力墙的抗侧承载力。研究结果表明:当墙板开不同位置方形洞口时,波幅为15mm的波纹钢板墙的整体承载力在开洞口6和7时是最低的,在洞口1时是最大的,最大和最低两者相差7%。采用30mm波幅的钢板墙开洞口9时承载力最大,开洞口12时其承载力最小,两者相差5.8%。当波幅为60mm时,洞口9和10对应模型的承载力是最小的,洞口4对应模型的承载力是最大的,两者相差3.56%。

Taking the corrugated steel plate shear wall with square openings at different positions as the research object, the lateral bearing capacity of the steel plate shear wall with 12 different openings is studied by a large-scale general analysis software, through nonlinear nappe analysis. The results show that the overall bearing capacity of corrugated steel plate wall with wave amplitude of 15 mm is the lowest at the openings 6 and 7, the largest at the opening 1, and the difference between the maximum and the lowest is 7%. The bearing capacity of the steel plate wall with 30 mm amplitude is the largest at openings 9 and the lowest at openings 12, and the difference between the two is 5.8%. When the amplitude is 60 mm, the bearing capacity of the corresponding models of the openings 9 and 10 is the smallest,and the bearing capacity of the corresponding model of the opening 4 is the largest, which is a difference of 3.56%.
