A Study on the Formulas of Effective Slenderness Ratio of Three-Leg Laced Lattice Column

Abstract:

The formulas of effective slenderness ratio of three-leg laced lattice column are given in the Design Specification of Steel Structure (GB50017-2003). Because the expressions of them are related with the sectional area of the column and the lacing bar, and the angle between the lateral lacing bar and theaxis etc, its used complicated. This article applied knowledge of structural mechanics to analyze the calculation process and result of three-leg laced lattice column and deduce more simple formulas. It is proved through practical examples that both simplification formulas and the Design Specification (GB50017-2003) formulas had a similar result, which provided reference to engineers.
