③ 摘要
在方空截面构成的桁架的N型节点处很容易发生塌陷破坏。为了使杆件破坏先于节点破坏,一个很好的方法就是将桁架的弦杆灌浆来提高空弦杆的坍塌承载力。进行了一个由灌浆方钢管构成的八个试样的N节点的试验。基于对试验的研究,进行了试件的几何参数分析,套箍系数ξ的效应、两个腹杆g之间的间距和垂直腹杆的侧向长度与基于试件性能的弦杆β的侧向长度的比值通过依靠ANSYS程序进行的模拟分析而被调查研究。基于试验结果和模拟分析,揭示了这种节点的力学性能和失效模式,预测相应于不同失效模式的极限承载力的公式也被得出。根据一根弦杆的坍塌失效模式受压N节点的极限承载力被计算出来;根据冲剪失效模式受拉N节点的极限承载力被计算出来;根据正剖截面的剪切失效模式,弦杆的极限承载力被计算出来
Cave—in failure is apt to occur in joints of trusses made of square hollow sections.In order to turn the failure mode into a strength failure mode of joint members,the idea is proposed that the chord of the truss is grouted to increase the cave—in beating capacity of a hollow tube chord.An experiment of eight specimens of N—joints made of grout—filled square steel tubes is performed.Based on the experimental study,the geometrical parameters of specimens are analyzed,and the effects of the confinement index ξ,the spacing between the two web members g and the ratio of side length of the vertical web member to that of the chord β on the behavior of specimens are investigated through simulation analysis by an ANSYS program. Based on the test results and simulation analysis,the mechanical properties and the failure modes of this kind of joints are analyzed and the formulate to predict the ultimate beating capacities corresponding to different failure modes are developed. The ultimate beating capacity of compressive N-joints is calculated in accordance with the cave—in failure mode of a chord member;the ultimate beating capacity of tension N-joints is calculated in accordance with the punching—
shear failure mode;the ultimate beating capacity of a chord member is calculated in accordance with the shear failure mode in normal sections.
