| Abstract: | To solve the design problem of the tube joints in the design of steel pipe structure,influences of β（β is ratio of branch pipe diameter and the main pipe diameter）and γ（γ is ratio of main pipe diameter and the main pipe Wall thickness） on ultimate flexural capacity of the X-shaped steel tubular joints were analyzed by establishing a finite element model in finite element programmer of ANSYS for X-shaped steel tubular joints which used a three-dimensional and four-joint elastic-plastic shell 181 elements and ideal elastic-plastic materials.Impact rules of various factors on ultimate flexural bearing capacity of X-shaped steel tubular joints were given. |
