【摘要】 采用有限元方法对2个不同尺寸的T型方钢管节点进行了有限元模拟和分析,并对2个T型节点的主管进行了加厚,研究了两个加厚参数加厚长度L_C和加厚厚度t_C对2个T型方钢管节点承载力的影响。通过对18个不同参数的主管加厚T型方钢管节点的研究分析发现:增加主管的厚度可以显著的提高节点的承载能力,但是厚度增加过大会产生新的破坏模式。而主管加厚部分的长度在达到一定值时再增加对节点承载力的提高不再明显。更多还原

【Abstract】 Two different geometry RHS T-joints are simulated and analyzed using finite element method,also the effect of the length and thickness of reinforced chord to the bearing capacity of the T-type RHS joints is studied through reinforcing the chord thickness with various length and thickness of reinforced chord.Through studying on 18 different reinforcement RHS T-joints,it can be concluded that the bearing capacity of a RHS T-joint can be greatly improved by reinforcing the chord thickness,but in order to avoid different failure mode,the reinforced chord thickness should not be much greater than the original chord thickness.Basically,it is not effective to improve the static strength of a RHS T-joint after the length of the reinforced chord thickness exceeds certain value.更多还原
