摘要
空间相贯管节点构造简捷 ,较多应用于大跨度空间结构 ,其受力状况较为复杂。运用有限元方法 ,分析了TX型圆管相贯节点在平面外支管受轴向荷载、平面内支管受平面外弯矩作用下的极限承载力 ,并利用圆环模型 ,结合非线性回归分析 ,推导了理论计算公式。
Multiplanar tubular joints are fabricated compactly and often applied in large-span space structures,but the failure modes are complex.With a finite element method,ultimate capacity of circular tubular TX-joints loaded by out-of-plane bending on the in-plane brace and axial forces on the out-of-plane braces was analyzed.The corresponding formulae were developed,based on the ring model and a nonlinear regression analysis.
