摘要:
为研究方钢管混凝土框架内置开洞薄钢板剪力墙的抗震性能,对4个单跨2层1/3比例的方钢管混凝土框架内置薄钢板剪力墙试件进行了低周反复荷载试验,4个试件分别采用中部开洞、单侧开洞、两侧开洞和未开洞钢板剪力墙.研究了开洞形式对方钢管混凝土框架内置薄钢板剪力墙抗震性能的影响,并与方钢管混凝土框架内置未开洞薄钢板剪力墙进行对比.得到了试件的滞回曲线、骨架曲线、各阶段的荷载和位移值及抗震性能指标,分析了结构的破坏特征、延性、耗能能力、承载能力及刚度退化等力学性能.结果表明:4个试件均能够发挥钢板剪力墙的屈曲后强度,滞回性能稳定,延性较好,承载力退化平缓.中部开洞薄钢板剪力墙被加劲肋分隔为宽厚比较小的区格,耗能能力优于其余3个试件.洞口边缘构件端部连接焊缝撕裂影响了单侧开洞和两侧开洞钢板剪力墙性能的充分发挥.钢板剪力墙开洞一定程度上降低了结构承载力和抗侧刚度,但提高了耗能能力.钢板剪力墙洞口边缘构件应具有足够的强度、刚度及连接强度.
Abstract:
In order to study the seismic behavior of the concrete-filled square steel tubular frame(CFSST)-thin steel shear plate walls(SPSWs) with openings, four one-third scaled one-bay and two-story CFSST-SPSWs specimens were designed for quasi-static experiments. The SPSWs of specimens were with middle openings, one side opening, two side openings and with no opening, separately. The influences of opening on the seismic behavior of SPSWs were investigated for CFSST-SPSWs, which were compared with the CFSST-SPSWs without opening. The hysteretic loops, skeleton curves, the load and displacement values for different loading stages and seismic behavior index were obtained. The failure characteristic, ductility, energy dissipation capacity, load bearing and stiffness degradation were studied. The results show that the post-buckling strength of the SPSWs of four specimens is developed. All the specimens have stable hysteretic behavior, good ductility and stable load bearing capacity degradation. The SPSWs with middle openings are divided into small zone with smaller width-to-thickness ratio by stiffeners. The energy dissipation capacity of the SPSWs with middle openings is better than the others’. The load bearing capacity of SPSW with one side and two side opening is affected by the weld tearing of the stiffeners surrounding the openings. The openings of the SPSWs decrease the load bearing capacity and lateral stiffness, but improve the energy dissipation. The strength, stiffness and the connection of the stiffeners surrounding the openings should be adequate in develop ing the tension field.
