国内外对钢板剪力墙的研究较少考虑竖向荷载的影响,这与工程实际不符.为准确估算钢板剪力墙承受竖向荷载后的弹性屈曲性能,对四边简支、两侧边固支上下边简支和四边固支矩形钢板剪力墙在剪压作用下的弹性稳定性能进行了有限元分析.根据有限元计算结果,修正了不同边界条件钢板剪力墙剪压荷载下的相关屈曲计算公式.与有限元结果和文献结果的比较表明,该文公式具有较高精度,可以在钢板剪力墙的设计中应用.
Domestic and international researches on steel plate shear walls take less consideration of the influence of vertical load, which is inconsistent with engineering practice.In order to accurately estimate the elastic buckling performance of steel plate shear walls subjected to vertical load, The elastic stability of simply-supported and four-legged rectangular steel sheet shear walls subjected to shear loading was analyzed by finite element method.According to the finite element calculation results, the correlations under different shear loads of steel sheet shear walls with different boundary conditions The calculation formula of buckling is compared with the result of finite element and the result of literature, which shows that the formula is of high precision and can be used in the design of steel plate shear wall.
