钢板剪力墙力学性能研究

Study on mechanical property of steel plate shear walls

钢板剪力墙作为新型的抗侧力体系,由于其延性系数大,滞回环饱满,内力重分布能力强等良好的抗震性能正逐步得到推广和应用.对比了薄、厚钢板剪力墙和薄腹梁的力学性能差异,对钢板剪力墙的试验成果、简化计算模型和骨架曲线进行了论述,给出了其极限承载力,屈服点位移,边框刚度和强度的有关算法,提出了初步设计方法和其应用于工程实践尚需解决的问题.

As an innovative lateral loading-resisting system, steel plate shear walls （SPSW） were applied gradually for desirable seismic capacity, excellent ductility, a robust resistance to degradation under cyclic loading and efficiency of stress redistribution. The mechanical property＇s differences of thick, thin SPSW and plate girders is compared. Achievements fron; the experiments, simplified strip model and skeleton curves are discussed. Solutions to ultimate capacity, yield displacement, frame rigidness and strength are suggested. Preliminary design method and problems that need solutions in praetice are set forth.
