Mechanical Behavior Study on Headed Studs for Composite Truss Joint
Finite element analysis (FEA) method is used to study the mechanical properties of headed studs for composite truss joint. The results show that the shear forces in the first few rows of headed studs are much greater than others. The shear forces in the rear headed studs decrease gradually. This study shows that the stiffness of headed studs, the layout of headed studs, and the steel backing plate are the main influencing factors on shear forces of headed studs. It is also expected that the results presented in this paper would be useful as references for the further research and the design of composite truss bridge and composite joint.
