Abstract:

基于对两种适用于超高层建筑的伸臂桁架-核心筒剪力墙节点的试验研究,对该类节点的抗震性能和受力机理进行精细有限元和理论分析,并给出设计方法和建议。首先利用通用有限元软件MSC.MARC(2010)对节点进行非线性数值模拟,将有限元分析结果与试验结果进行对比分析,取得满意的结果。随后根据有限元计算结果对伸臂桁架、墙体端部暗柱、外包(内嵌)钢板和混凝土剪力墙的受力机理进行深入分析,同时给出节点承载力简化计算方法。最后在整体节点模型的基础上,建立节点板的局部模型,着重对节点板的受力机理进行分析,并考察该类节点板简化设计公式的适用性。分析结果表明：混凝土墙受到上下部钢板的剪切作用从而形成斜压杆受力机制；在剪切荷载存在且节点板长度较小时,节点板危险截面正应力分布并不符合平截面假定。该文研究可为超高层建筑中伸臂桁架-核心筒节点的设计与施工提供参考。
