| 摘 要： | 要深入了解梁-墙平面外连接节点的受力性能,特别是发生"拉脱破坏"的原因,需要明确平面外弯矩在剪力墙临界截面上引起的弯矩和扭矩的传递比例。通过有限元计算,对影响剪力墙截面力分布和节点弯矩传递比例的主要因素,如梁、墙截面尺寸以及边界条件等进行了参数分析;在此基础上,利用简化模型推导了节点弯矩传递比例的理论计算公式,并进行了数值拟合;通过与分析结果和ACI无梁楼盖相关计算公式的对比发现,ACI公式明显低估了抗弯条带的弯矩传递比例。

| Abstract: | In order to analyze the mechanical behavior of out-plane beam-wall joint,especially the reason of 'pulling-out' damage,the moment transfer factor of joint should be defined firstly.Using FEM analysis,the parametric study was carried out,to determine the dominant parameters influencing the distribution of sectional forces within the wall and the moment transfer coefficients.By the theoretical deduction,the formula for moment transfer factor was proposed and fitted with the analysis data,and comparison betwee... |
