Finite Element Analysis of Dual-Angle Variable of Four Steel Angle Composite Joint with Steel Materials in Civil Engineering
In the multiple-circuit on same tower UHV and large crossing transmission tower,The main material of towers usually using a composite section in the form of the dual-angle and four steel angle. Dual-angle and four steel angle connections are inevitable. 500KV Jianbi - Danfeng four circuit transmission line project for the background, Using the finite element software ANSYS10.0, Composite Joints three-dimensional nonlinear finite element simulation. Clear the path of force transferor the node, Mechanical behavior of gusset plate and node failure modes. The results show that: node failure modes for the strength failure, The ultimate bearing capacity of the node is about three times the load of the node design, Node design is relatively conservative, By reducing the thickness of the gusset plate to lower node weight.
