| 摘 要： | 针对抗剪连接件剪力分布的不均匀程度缺少理论分析的现状,利用弹性变形理论,推导了多排抗剪连接件在竖向荷栽作用下相对滑移和剪力分布的理论计算公式,并与有限元计算结果进行了验证.结果表明,钢板端部固定可以改善连接件的受力状态,且钢、混凝土受力分布也较为均匀;多排抗剪连接件刚度和间距越大剪力分布越不均匀.得到了竖向荷载作用下多...

| Abstract: | The distribution of shear along an interface between steel and concrete is generally non-uniform and none theoretic analysis for the non-uniform level.Using elastic deformation theory,the analytical formula of interface slip between steel and concrete and shear distribution of multi-row shear connectors under vertical loads were derived.The 3D numerical FE model was served to calibrate the analytical results.The result shows that(1) shear distribution of connectors can be improved by end fixation of steel,w... |
