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。
In the Wenchuan earthquake, a large number of frame structures were damaged due to the insufficient lateral stiffness of the columns, and the addition of a wall structure reinforced by the wing walls could effectively increase the lateral stiffness of the frame. Through the analysis of the actual bearing capacity of the column, the NM curve and the Mx-My curve of the normal cross section of this kind of special-shaped cross-section under the bidirectional eccentricity are obtained by numerical integral method. And in the actual project, Mx-My envelope diagram of different reinforcement of wing wall provides reference for cross-section design and section review.
