摘　　要：受薄钢板剪力墙简化计算模型——斜拉杆模型的启发,提出双向拉压杆模型(LY-S)来简化模拟十字加劲钢板墙,其简化计算方法有助于工程设计与模拟分析.利用有限元软件ANSYS对拉压杆模型进行单向荷载分析以及循环荷载分析,并与相对应的十字加劲钢板墙模型进行对比分析,验证了双向拉压杆简化模型模拟十字加劲钢板墙的合理性;双向拉压杆模型的初始弹性刚度较十字加劲钢板墙模型偏小,在内填钢板高厚比大于170时,二者拟合良好.Inspired by the simplified calculation model of thin steel plate shear wall, or the oblique rod model, bidirectional trolley-strut model （LY-S） was proposed to simplify cross-stiffened steel plate Walls. Compared with the analysis of cross-stiffened steel plate wall model, the unidirectional load analysis and cyclic loading analysis of the LY-S were conducted by finite element software ANSYS. The validation of LY-S to simulate the cross-stiffened steel plate walls was verified. The initial elastic stiffness of the LY-S is weaker than the cross-stiffened steel plate wall model. When the heightthickness ratio of the infill steel plate was greater than 170, two models fitted well.
