通过对钢管结构无加劲法兰承力的系统试验,分析了无加劲法兰的变形和受力状态,研究了法兰承载力与法兰盘厚度、螺栓边距、螺栓疏密及偏心距的关系,并提出了合理的螺栓受力修正系数和法兰承载力计算公式。
Through the system test on the steel tube without stiffened flange, the deformation and stress state of the stiffened flange were analyzed. The bearing capacity of flange and flange thickness, bolt margin, bolt density and eccentricity The reasonable bolt force correction coefficient and flange bearing capacity formula are put forward.
