钢框架短肢组合钢板剪力墙结构是一种适用于小高层的建筑新型框架剪力墙结构,它具有良好的抗震性能。以影响结构抗震性能的内嵌钢板宽厚比、面外墙板约束及钢板边界约束等4个因素进行了分析。通过总结各影响因素,进行了结构单元动力响应的数值模拟分析,提出了组合钢板剪力墙与钢框架的合理抗侧刚度比及合理的内嵌钢板剪力墙宽厚比。优化后的结构模型试验证明:当钢框架短肢组合钢板剪力墙结构中各构件在整个结构中达到最优设计,同时抗侧刚度比在0.42~0.45之间时,结构整体具有较高的水平承载能力,良好的抗震和耗能能力。最后提出了钢框架短肢组合钢板剪力墙的优化设计建议。
The steel frame short-legged combined steel plate shear wall structure is a new type of frame shear wall structure suitable for small high-rise buildings, which has good seismic performance. The factors such as inlaid plate thickness-to-thickness ratio, surface-wall-panel constraint and steel-plate boundary constraint, which influence the seismic performance of the structure, were analyzed. Through summarizing the influencing factors, the numerical simulation analysis of the dynamic response of the structural element is carried out. The reasonable lateral stiffness ratio of the combined steel plate shear wall and the steel frame and the reasonable inlaid ratio of the embedded steel plate shear wall are proposed. The optimized structural model test proves that when the components in the steel frame short-legged combined steel plate shear wall structure reach the optimal design in the whole structure and the lateral stiffness ratio is between 0.42 and 0.45, the structure has a higher Horizontal carrying capacity, good seismic and energy dissipation capabilities. Finally, the optimal design proposal of steel frame short-limb composite steel plate shear wall is put forward.
