防屈曲开缝钢板墙是一种新型的抗侧力构件,除具有一般钢板墙的特点外,还具有塑性性能好、滞回特性稳定以及可以独立地变化墙板承载力和刚度等优点。目前,有学者针对该结构体系提出基于性能设计的能力设计法和能力准则法,采用上述理论以及日本被动减震结构的设计方法(性能需求法),对1榀6层3跨的防屈曲开缝钢板墙结构算例进行了分析,比较研究了3种方法对结构性能的影响。计算结果表明:对于能力设计法,适当提高墙板的设计屈服位移,可以有效地增大结构的延性;能力准则法需要多次试算,结构性能指标不易控制,通过承载力控制设计墙板屈服位移,耗能效率较高;性能需求法得到的结构延性最好,但用钢量较大,应用于防屈曲开缝钢板墙设计,尚需解决框架梁设计、墙板屈服位移取值等问题。
Anti-buckling seam wall is a new type of anti-side force components, in addition to the general characteristics of the steel wall, but also has good plasticity, hysteresis stability and can independently change wall bearing capacity and stiffness advantages. At present, some scholars put forward the capability design method and capability criterion method based on the performance design for the structural system. Based on the above theory and the design method (performance requirement method) of Japanese passive damping structure, An example of steel wall structure was analyzed, and the influence of three methods on the structure performance was compared. The results show that for the capability design method, the ductility of the structure can be effectively increased by appropriately increasing the design yield displacement of the wallboard; the capacity criterion method needs several trial calculations, the structural performance index is not easy to control, and the design of the wallboard yielding by the bearing capacity control Displacement and high energy dissipation efficiency. The structural ductility obtained by the performance requirements method is the best, but the steel used in the design of the buckling-resistant steel plate wall is still required to solve the problems such as the design of the frame beam and the yield displacement of the wall plate .
