摘要:
对竖向闭口槽钢加劲钢板剪力墙在非均匀压应力和剪应力共同作用下的屈曲性能进行了有限元分析,得到了竖向闭口槽钢加劲钢板剪力墙的临界屈曲剪应力随加劲肋加劲系数的变化曲线及阈值刚度,提出了剪应力和竖向压应力共同作用下加劲肋阈值刚度的计算公式。结果表明:加劲肋阈值刚度随着小区格宽高比、竖向压应力非均匀系数、加劲肋数目和加劲肋抗扭刚度与抗弯刚度比增大而减小;提高加劲肋抗扭刚度与抗弯刚度比能显著降低加劲肋阈值刚度;加劲肋阈值刚度公式计算结果与有限元分析结果吻合较好。
Abstract:
The buckling behavior analysis of steel plate shear wall (SPSW) stiffened by vertical closed channel stiffeners under the combination of non-uniform vertical compression stress and shear stress was carried out by using finite element software. The curves relating the critical buckling shear stress of SPSW stiffened by vertical closed channels to the stiffening coefficient of stiffeners and threshold stiffness were obtained. The formulas were proposed to calculate the threshold stiffness of the stiffeners under the combination of shear stress and non-uniform vertical compression stress. The results show that threshold stiffness decreases with the increase of the width-to-height of portion, non-uniform compressive stress coefficient, the number of stiffeners and the ratio of the torsional stiffness to the flexural stiffness of the stiffeners. The threshold stiffness of stiffeners decreases significantly with the increase of the ratio of the torsional stiffness to the flexural stiffness of stiffeners. The formula calculation results of threshold stiffness agree well with the finite element analysis results.
