| 摘 要： | 汶川地震中,大量框架结构由于柱抗侧刚度不足产生破坏,增设翼墙加固框架结构能有效提高其抗侧刚度.通过对实际工程的翼墙加固柱进行了截面承载力分析,采用数值积分方法得出此类异形截面在双向偏心作用下正截面的N-M曲线、Mx-My曲线,并计算出实际工程中,单片翼墙不同配筋的Mx-My 包络图,为截面设计及截面复核提供参考依据.

| Abstract: | A large number of frames damaged due to the poor lateral stiffness in Wenchuan Earthquake.Additonal flange wall could effectively improve the lateral stiffness.This paper analyzed the bearing capacity of special-shaped column of the practical engineering structures;meanwhile,it was obtained N-M curve and Mx-My curve of biaxial eccentricity compression based on numerical integration method.In addition,the Mx-My envelope diagram of an actual project was also calculated,which could provide a reference for section design and check. |
