【摘要】：为简化带有X型屈曲约束钢板墙的结构体系受力分析,提出用交叉支撑模型来模拟X型屈曲约束钢板墙。当钢板墙高宽比小于1.5时支撑点取在距墙边缘h/10处,当钢板墙高宽比大于等于1.5时支撑点取在距墙边缘b/6处。等效交叉支撑杆件的截面面积和材料强度按与X型屈曲约束钢板墙的初始刚度和屈服承载力相等进行换算。对提出的简化分析模型进行了对比验证,分析结果表明该模型能够准确模拟X型屈曲约束钢板墙及其在框架结构中的受力行为,且不受加载方向和钢板墙高宽比的限制,可以作为两边连接X型屈曲约束钢板墙的等代模型进行结构受力分析。
[Abstract]:In order to simplify the stress analysis of steel plate wall with X-type buckling constraint, a cross-bracing model is proposed to simulate the buckling steel plate wall. When the aspect ratio of steel plate wall is less than 1.5, the supporting point is taken at 10 points from the edge of the wall, and when the ratio of height to width of steel plate wall is greater than 1.5, the supporting point is taken at the point b / 6 from the edge of the wall. The cross-section area and material strength of the equivalent cross-braced member are equivalent to the initial stiffness and yield bearing capacity of the X-type buckling steel plate wall. The proposed simplified analysis model is compared and verified. The results show that the proposed model can accurately simulate the behavior of the steel plate wall with buckling constraint and its behavior in the frame structure, and is not limited by the loading direction and the ratio of height to width of the steel plate wall. It can be used as the equivalent model of X-type buckling steel plate wall.
