摘　　要：为了检验X型钢支撑对框架结构抗侧能力的影响,本文以一个一榀框架为背景,对其加中心X支撑前后进行静力非线性pushover分析,通过对框架结构的塑性铰的发展情况以及层间位移大小比较的分析研究两种框架的抗震性能。试验结果表明:在框架处于弹性阶段的时候,塑性铰均先出现在梁端,但是带X型支撑的框架塑性发展比纯框架慢约50%,抗侧刚度也有明显提高。In order to test X-type steel support effect on lateral resistant ability of frame structure, this paper takes a pin frame as the background, making a nonlinear static Pushover analysis before and after adding the central X-type support, and through analyzing the plastic hinge development of the frame structure and the comparison of the displacement between layers, studies the seismic behavior of the two types of frameworks. The results show that when the frame is in the elastic stage, the plastic hinge first appears at the end of the beam,but the plastic development of the frame with X-type is about 50% slower than that of the pure frame; the lateral stiffness is also significantly improved.
