- Abstract:
- The unilateral bolt connection nodes of new type concrete filled steel tubular columns with outershell and steel beam was put forward by summing up the previous deficiency of connection nodes. Based on theexperimental and theoretical analysis,in consideration of the initial geometric imperfections of steels and con-crete damaged plasticity model,end-plate connections for concrete filled steel tubular columns and steel beamwith outer-shell and without outer shell finite element models were established respectively.Under monotonicloading in finite element model,analysis the damage and working mechanism; according to parametric study a-nalysis the main factors of initial stiffiness and bearing capacity for joints and establish M-0,practical model fornew type joints. The results show that the joints with outer-shell have greater initial stiffness and bearing ca-pacity and better seismic performance.The M-0,models which was presented in this paper are reasonable andreliable.It can provide a reference for theory design and real engineering application.
