Abstract:
In order to investigate the static work behavior of square hollow section(SHS)truss with gapped K-joints, nonlinear finite element analysis of four trusses which directly welded K-joints was carried out. Making use of finite element analysis software ANSYS, in which four nodes shell element was employed, elastic-plastic large deflection finite element analysis of truss was conducted. Not only the upward and downward phases of the load and displacement curve were traced, but also deformation and plastic development situation of joints were studied. The four truss models of pin-jointed link elements, rigid-jointed beam elements, shell elements as well as shell elements which took weld into account were developed. Axial forces of web bars and chord bars of these four truss models bearing designed load were compared. Besides, the whole stiffness of four different truss models bearing standard load was compared.
