| 摘 要： | 采用能量原理推导了设置竖向加劲肋钢板墙的弹性屈曲应力的简化计算公式,并根据理论公式进行了参数分析,研究了钢板高宽比、加劲肋数量、加劲肋与钢板刚度比以及加劲肋与钢板面积比等参数对钢板墙竖向屈曲荷载的影响。简化公式计算结果与有限元计算结果吻合良好。研究表明,在钢板墙高宽比确定的情况下,加劲肋与钢板的刚度比是影响加劲板竖向屈曲荷载的主要因素,加劲肋与钢板的面积比对加劲板屈曲荷载的影响较小,加劲肋端部与周边框架不连接的钢板墙优于加劲肋端部与周边框架连接的钢板墙。

| Abstract: | Simplified theoretical equation for critical buckling stress of vertical stiffened steel plate shear wall(SPSW) was derived by energy principle.Parametric analysis was conducted to identify the main parameters affecting the vertical buckling behavior of stiffened SPSW.These parameters include the aspect ratio of the plate,the number of stiffeners,bending stiffness ratio,area ratio etc.The results of the formula fit well with the FEA analysis.Based on the theoretical analysis,it turns out that the bending st... |
