三层钢板剪力墙结构静力推覆试验研究

STATIC PUSHOVER TEST OF THREE-STORY STEEL PLATE SHEAR WALLS

  • 摘要: 通过按照我国相关规范设计的三层钢框架-钢板剪力墙结构在水平单调荷载作用下的静力推覆试验研究,得到了结构的破坏模式、底部剪力与顶点位移及层间位移曲线、剪力墙板的平面外变形、承载力和延性。结果表明:试件在水平设计荷载时,墙板没有出现屈曲,结构保持完全弹性;二层剪力墙板右下角最先达到受拉屈服,但当荷载加载到后期,底层剪力墙板出现的平面外变形最大;试件在达到极限承载力之后,强度下降非常缓慢,结构具有良好的塑性变形能力,位移延性系数为5.24;试验终止时,二层的层间变形最大,层间位移角达到了0.0447rad,柱脚翼缘出现两个半波状的局部屈曲变形,腹板受压鼓曲。

     

    Abstract: The failure mode, curves of base shear versus roof displacement and inter-story drift, maximum out-of-plane displacement, bearing capacity and ductility performance were obtained from the static pushover test of three-story steel frame-steel plate shear wall systems subjected to horizontal monotonic loading. The prototype structure of specimen was designed according to the corresponding design codes in China. The results show that the shear walls don’t undergo buckling and the structure remains fully elastic under the calculated design load. The yielding occurs firstly in the lower right corner of the infill panel at the second story, but the maximum out-of-plane deformation appears in the bottom shear panel at later loading stage. With good capacity of plastic deformation, the specimen’s strength drops very slowly after the peak value and the displacement ductility coefficient reaches 5.24. At the end of test, the second story has the maximum inter-story drift and the corresponding inter-story drift ratio is 0.0447rad. The local buckling with two-half-wave shape occurs in the flange of steel column base and the outward buckling due to the compression force appears at the web.
