摘　　要：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。The buckling-restrained slit steel plate wall ( BRSSPW ) in general is a new-type lateral resistant member.Besides having the characteristics of traditional steel plate shear walls , it still has many advantages such as good plasticity performance , stable hysteresis characteristics and the bearing capacity and stiffness can be independently adjusted.At present , some scholars have proposed capacity design method and capacity criteria method which are performance-based seismic design approaches for this structural system.In this paper , by using the above two approaches and the Japanese design method ( performance demand method ) for passively-controlled structure , a six-story , three-span BRSSPW structure was designed to compare their influence on the performance of structure.The calculation results show that : for capacity design method , by appropriately increasing steel plate wall's yielding displacement , the ductility of the structure can be effectively increased.For capacity criteria method , trial calculation needs to be conducted for several times , and the structural performance index is difficult to assess.Meanwhile the wall-plate yielding displacement is designed under control by loading capacity , but with relatively high energy dissipation efficiency as a result.The best ductility could be obtained in a structure designed with performance demand method , but requiring a higher steel consumption.When it is applied in designing BRSSPW , issues of designing frame beams and determining the yielding displacement of steel plates need to be solved.
