EXPERIMENTAL RESEARCH ON SEISMIC PERFORMANCE OF PREFABRICATED SHEAR WALL WITH CONCRETE FILLED STEEL TUBE FRAME UNDER RAPID RECIPROCATING LOAD

摘要

摘要: 为研究快速往复荷载下装配式钢管混凝土边框剪力墙的抗震性能，设计制作了3片足尺单层单跨装配式钢管混凝土边框剪力墙试件，分别进行0.1，5，20 mm/s加载速率下的往复荷载试验，对其破坏形态、滞回曲线、骨架曲线、承载能力、延性系数、耗能能力及刚度退化等方面进行对比分析。试验结果表明：试件破坏均为墙体边框钢管屈服后底角混凝土压溃，而钢筋及钢管连接节点处未发生明显变化，说明套筒灌浆连接技术满足装配式结构受力要求。加载速率对装配式钢管混凝土边框剪力墙的抗震性能影响有限，加载速率较静态加载提高200倍时，剪力墙承载力提高6%，延性系数降低20%，等效黏滞阻尼比降低13.1%。

Abstract: In order to study the seismic performance of prefabricated shear wall with concrete filled steel tube frame under the rapid reciprocating load, three full-scaled single-layer single-span precast concrete-filled steel tube frame shear wall specimens were designed and fabricated. The reciprocating loading tests were carried out under the loading rates of 0.1, 5, 20 mm/s respectively, and the failure modes, hysteresis curve, skeleton curve, bearing capacity, ductility index, energy dissipation capacity and stiffness degradation were analyzed. The test results showed that all specimens were broken by concrete collapse at the bottom corner after the frame steel tube yielding, while the joints of steel bar and steel tube did not deform significantly, indicating that the sleeve grouting connection technology could meet the stress requirements of the prefabricated structures. The loading rate had limited impact on the seismic performance of prefabricated shear wall with concrete filled steel tube frame. When the loading rate was 200 times higher than the static loading rate, the bearing capacity of the shear wall increased by 6%, the ductility index decreased by 20%, and the equivalent viscous damping coefficient decreased by 13.1%.
