DESIGN INTERACTION EQUATIONS FOR CYLINDRICAL TUBULAR BEAM COLUMNS

The current AISC (American Institute of Steel Consturction) equations are reviewed to highlight the development of the proposed interaction equation, and an extensive evaluation of the proposed equation is made comparing with the results of the exact inelastic solutions reported by Chen and Toma (1979) and Sherman et al (1979), as well as the full-scale tubular column tests by Ellis(1958), and others. The interaction equations for load and resistance factor design (LRFD) are also evaluated in light of the proposed equation. The proposed equation has a smooth transition from the pure bending case to the pure axial load case, and is valid for long as well as short members. The equation is less conservative but more acurate than the formulas used in the current LRFD specifications.
