Abstract

As a new type of steel sections,lipped H-section members have excellent load-carrying efficiency and economic efficiency,compared with common H-section members.The load-carrying capacity of lipped H-members under axial load is studied by FEM,where with the large deformation,material elastic-plasticity, the geometric initial deflects and residual stress of the members taken into account,the influence of sectional geometric parameters and slenderness ratio on load-carrying capacity of the lipped H-section members are analyzed.Finally,based on a lot of FEA numerical results obtained,the design formulas are obtained for predicting load-carrying capacity of lipped H-members under axial loads.
