【摘要】 提出了钢管混凝土边框内藏钢板组合剪力墙。完成了12个不同构造的钢板组合剪力墙模型的低周反复荷载试验,其中包括5个钢管混凝土边框纯钢板剪力墙、7个钢管混凝土边框内藏钢板剪力墙。分析了各试件的承载力、耗能、延性、滞回特征等。给出了部分组合剪力墙的承载力计算模型,计算结果与试验结果符合较好。研究表明,钢管混凝土边框内藏钢板组合剪力墙具有承载力高、延性好、耗能能力强、滞回性能稳定等特点。这种新型组合剪力墙已用于工程,效果良好。更多还原

【Abstract】 The embedded steel plate concrete shear wall with concrete filled steel tube col umns was proposed.The tests of 12 shear wall specimens under cyclic loading hav e been accomplished,including 5 specimens of pure steel plate shear wall with co ncrete filled steel tube columns and 7 specimens of embedded steel plate concret e shear wall with concrete filled steel tube columns.The performances of specim ens such as load-bearing capacity,energy dissipation,ductility and hysteretic behavior have been investigated.Formulas for load-bearing capacity of some sp ecimens are put forward and the calculation results agree well with the experime ntal ones.It is shown that the embedded steel plate concrete shear wall with co ncrete filled steel tube columns has excellent aseismic features of higher capac ity,better ductility,larger energy dissipation and more stable hysteretic behav ior.This new kind of composite shear wall has been applied to the actual projec ts and the received response is satisfactory.更多还原
