摘要

采用ANSYS有限元软件对大高宽比钢板剪力墙进行了弹塑性分析。研究不同侧加劲刚度下钢板墙的性能,分析钢板墙承载力与侧加劲构件的关系以及横撑对侧加劲构件和钢板墙的影响。结果表明:两侧理想加劲可以使钢板墙承载力充分发挥,同时设置横向支撑可显著减小侧加劲构件的截面尺寸。通过研究给出了侧加劲构件的设计建议。
Elastoplastic analysis of a new type of steel plate shear wall (SPSW), named large aspect ratio SPSW (LAR-SPSW) was carried out by the finite element software ANSYS in this paper. The behavior of LAR-SPSW with different boundary stiffeners was discussed. The relationship between the bearing capacity of LAR-SPSW and the boundary stiffeners, and the influence of the horizontal brace on the boundary stiffeners and LAR-SPSW were analyzed. The analytical results showed that the full development of the bearing capacity of LAR-SPSW can be attained with reasonable boundary stiffeners, and the stiffeners can be optimized by applying horizontal brace(HB). The research also provides designing suggestions for the boundary stiffeners.
