| 摘 要： | 我国现行加劲钢板剪力墙整体屈曲临界应力计算公式来自密肋加劲板,但实际工程中采用的钢板剪力墙多采用1条或2条横向加劲肋。对1600多个加劲钢板剪力墙模型进行了三维有限元弹性屈曲分析,深入研究了仅设置竖向加劲肋、竖向和1条横向加劲以及竖向和2条横向加劲肋钢板的加劲肋门槛刚度要求。并提出了加劲钢板剪力墙弹性剪切临界应力计算公式。与数值模拟结果的比较表明,新公式具有良好的精度,并且公式结果均在安全一侧,有望在工程中得到应用。

| Abstract: | The current design formula for the critical shear stress in JGJ99-98(Technical specification for steel structure of tall buildings) is applied mainly to the design of closely-stiffened plates.However,in practice,the steel shear walls are often stiffened with 1 or 2 longitudinal stiffeners.This paper presents a new study on the elastic buckling of the sparsely-stiffened plates under shear loading.More than 1,600 models are analyzed with the 3-D finite element method(FEM).The plates transversely stiffened wit... |
