Advanced Analysis of Steel Frame Structures Comprising Non-Compact Sections
The conventional advanced analyses assume the sections to be compact, and do not account for the degradation of the flexural strength caused by local buckling. Since the sections of real structures are not always compact, the analysis should be improved to consider local buckling. Based on the finite element model, using flexural tangent and axial tangent modulus to consider the effect of local buckling, a concentrated plasticity method suitable for practical advanced analysis of planer steel frame structures comprising non-compact sections is presented in the paper. The accuracy and precision of the method is established by comparison with steel frame tests.
