EXPERIMENTAL STUDY ON SEISMIC BEHAVIOR OF LIGHT-GAUGE STEEL WALL FILLED WITH GLAZED HOLLOW BEAD MORTAR

  • 摘要: 研究一种适用于村镇多层住宅的新型轻钢龙骨玻化微珠保温砂浆墙体。为研究此墙体的抗震性能,制作了3个缩尺比例为1∶1.25的试件。通过拟静力往复加载试验研究其破坏模式,根据试验获得的滞回曲线考察其承载力、延性、耗能能力及刚度退化等抗震性能。试验结果表明:墙体在层间位移角1/1000时仍保持弹性,在层间位移角1/100时承载力未出现明显下降;墙体的破坏模式表现为剪切破坏,但由于周边钢结构的约束效果仍然具有较好的延性和耗能能力。提出该墙体简化水平承载力计算公式,计算值与试验值的误差小于10%。
    Abstract: A new type of light-gauge steel wall filled with glazed hollow bead mortar is proposed for multi-story buildings in rural area. To investigate the seismic behavior of the wall, three 1:1.25 scaled specimens were tested using cyclic quasi-static loading scheme. The failure mode of those walls was investigated. The strength, ductility, energy dissipation capacity and stiffness degradation behavior were obtained from the hysteretic curves. The test results indicate that the structure remain elastic when the story drift angle is no more than 1/1000, and the strength does not significantly decrease when the story drift angle reaches 1/100. The failure mode is shown to be a shear failure; however, relatively good ductility and energy dissipation capacity were observed due to the restraint effect of the surrounding steel elements. Simplified equations were proposed to estimate the strength of the walls, and good agreement with an error no more than 10% was achieved between the strength estimated by the equations and those obtained from the tests.
