| 摘 要： | 以实际工程为背景,对体型不规则异形柱框架结构进行了弹性及弹塑性分析,计算出了结构弹性位移、扭转系数及结构的抗倒塌性能等结构抗震性能等指标,并分析了异形柱截面柱肢高宽比对结构整体抗震性能的影响。结果表明,体型不规则异形柱框架结构在7度抗震烈度下l/Bmax、l/b及高度均超限的情况下仍然具有较好的抗震性能;增加异形柱截面柱肢高宽比可以相应地提高异形柱框架结构整体抗震性能。分析所得出的结论可供设计人员进行参考。

| Abstract: | In order to research the space seismic behavior of specially shaped column frame structure of irregular shape,the calculated models were set up based on a actual project to analyze the elastic and elastic-plastic behavior of the models. And is was calculated the indexes,such as the elastic displacement,tensional coefficient and the collapse of the performance of the structures,and also analyzed the effect of the aspect ratio of the specially shaped column on the seismic behavior of this structure. The results showed that specially shaped columns frame structure of irregular shape had a good seismic behavior under 7 degrees of intensity,increasing the aspect ratio of the specially shaped column can improve the space seismic behavior of specially shaped column frame structure of irregular shape.These conclusions provide a reference for the designers. |
