| 摘 要： | 进行了两组双钢板-混凝土组合剪力墙拟静力抗震性能试验,研究了该类结构的受力机理,并得到其典型破坏形态。试件均表现出良好的延性和耗能能力,滞回曲线饱满稳定,极限位移角均超过现行规范的规定限值,且大于其他类似试验的结果。缀板拉结措施可有效避免墙身钢板的局部屈曲,同时可加强对内填混凝土的约束作用,使高强混凝土在抗震剪力墙中的应用成为可能,从而很好地满足了超高层建筑结构对剪力墙高轴压、高延性、薄墙体的设计需求。在试验研究的基础上,开展了理论分析和数值模拟,对双钢板-混凝土组合剪力墙在工程中的应用提出了初步设计建议,对有待进一步开展的研究工作进行了展望。研究表明,双钢板-混凝土组合剪力墙具有延性好、耗能能力强、构造简单、施工方便、避免裂缝外露等优点,在超高层建筑结构中具有广阔的应用前景。

| Abstract: | Quasi-static tests on seismic behavior of two groups of composite shear walls with double steel plates and filled concrete were conducted to investigate the structural mechanism and the typical failure modes.In the tests,all the specimens illustrated good ductility and energy dissipation ability with stable and full hysteretic curves.The ultimate drifts of all the specimens exceeded the limit value recommended by the current design code,and were also larger than the similar test results provided by other re... |
