摘要: 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。

Abstract: Based on the experimental research on two kinds of outrigger truss-shear wall joints which are applicable to super high-rise buildings, further elaborate analysis using the finite element and theoretical methods are conducted for the seismic behavior and load transfer mechanism of the joint. According to the analysis results, design methods and proposals for the joints are given. Firstly the nonlinear numerical simulation of the joint is done by using finite element program MSC.MARC (2010). The finite element analysis results correlate well with the test results. Furthermore, the stress distribution of the outrigger truss, concealed ending column, outside (encased) steel plate and concrete wall are discussed and the simplified method to assess the bearing capacity of the joint is proposed. Finally a local model of the joint plate is established based on the whole model of joints and the load transfer mechanism of the plate is analyzed. The reasonableness of simplified design formula for this kind of joint plate is discussed. Analysis results indicate that the concrete wall between the upper and lower steel plates is under shear and a diagonal strut is thus formed; the assumption of plane section is not followed on the critical section of the plate due to the existence of shearing load and short plate. Conclusions drawn in this paper are helpful for the design and construction of the outrigger truss-wall joint in super high-rise buildings.

Key words: super high-rise building, outrigger truss, composite joint, nonlinear finite element analysis, joint plate, plane section assumption, load transfer mechanism
