PERFORMANCE OF STEEL PORTAL FRAME WITH LOCAL BUCKLING OF TAPERED H-SECTION BEAM OR COLUMN
Based on nonlinear finite element method, steel portal frames with tapered members are analyzed, where the initial geometry imperfection of the frame and members, yielding and large deflections are taken account. According to the results, the effect of the degree of initial geometric imperfection is discussed and the failure mechanism of steel portal frame considering the post-buckling behavior of thin-walled plates is studied. Finally, the effect of width to thickness ratio of beam web on performance of steel portal frame is focused.
