中文摘要：

采用有限元软件ABAQUS 6.10对薄钢板剪力墙屈服点为235 N/mm2和345 N/mm2的钢框架-薄钢板剪力墙进行了非线性数值分析,对二者的承载力、刚度、剪力分配、滞回性能及延性等进行了研究.结果表明：薄钢板剪力墙屈服点对初始承载力、刚度和剪力分配影响很小;当薄钢板剪力墙屈服后,其屈服点越高,承载力和刚度亦越大,钢板剪力墙承担的剪力越多;高屈服点薄钢板剪力墙会增加受压柱的负担,使其屈曲位置上移,降低对薄钢板剪力墙的有效锚固;加载初始阶段,低屈服点薄钢板剪力墙先于高屈服点薄钢板剪力墙屈服耗能;达到理想破坏的钢框架-薄钢板剪力墙具有很好的延性.

英文摘要：

Nonlinear numerical analysis is conducted on the steel frame-thin steel plate shear walls with 235 N/mm2 or 345 N/mm2 yield point by using the finite element software ABAQUS 6.10. The load carrying capacity, stiffness, shears distribution, hysteretic behavior and ductility are investigated. Results obtained from this study are as follows： The yield point of thin steel plate shear walls has no influence on the initial load carrying capacity, stiffness and shears distribution. After the thin steel plate shear walls yield, the higher the yield point, the higher the beating capacity; and the larger the stiffness, the more the distributed shear. Higher yield point thin steel plate shear wall will increase the tension action of compressed column, which will move up the column＇s buckling and reduce the effective anchorage of steel plate shear walls. At initial loading stage, lower yield point steel plate shear walls yield earlier than higher yield strength steel. The thin steel plate shear walls with idealized failure mechanism have excellent ductility.
