| 摘 要： | 通过对一榀底层为宽肢的钢筋混凝土异形柱框架与一榀底层为非宽肢的异形柱框架的抗震试验研究,重点对比了两种异形柱框架结构的破坏特征、承载能力、延性、滞回特性、出铰顺序及刚度退化等抗震性能.分析结果表明,底层采用宽肢异形柱后可避免普通异形柱框架结构底层刚度薄弱的不利现象,并能不同程度地改善普通异形柱框架结构的多项抗震性能,提高了异形柱框架结构整体的抗震能力.

| Abstract: | Based on experimental research on the seismic behaviors of two frames,one with specially shaped columns, and the other with wide flange specially shaped columns on the first floor,the failure characteristics,bearing capacity,ductility,hysteresis properties,subsequence of hinge occurence and rigidity degeneracy of the two specimens were compared.The results show that the adoption of wide flange improves the rigidity of the columms on the first floor and correspondingly some other seismic behaviors of frame with normal specially shaped columns to resist the earthquake effectively. |

| Keywords: | RC frame specially shaped column wide flange low frequency cyclic loading seismic behavior |
