ADVANCED ANALYSIS OF STEEL FRAME STRUCTURES ACCOUNTING FOR LOCAL BUCKLING

摘要：

The application of advanced analysis methods has previously been restricted to steel frames comprising only compact sections that are not influenced by the effects of local buckling,to provide benchmark solutions for verification of the concentrated plasticity methods of space steel frames accounting for local buckling,a second-order distributed plasticity model is developed using shell finite elements. Details of the modeling including element type,mesh discretization,material model,residual stresses,initial geometric imperfections,boundary conditions,and load applications are presented. The model is verified by comparison with large-scale steel space frame test results. The ultimate loads of the space steel frames obtained from the proposed analysis and experiment compare well within 7% error. The benchmark solutions of the space steel frames are useful for the verification of various simplified second-order inelastic analyses.
