Abstract

It is given the comparison of specifications for the stability design formulas in American ANSI/AISC 3602005,British 595012000,Canadian CAN/CSAS162001,Australian AS 41001998,Japanese AIJ2002 and Chinese GB 500172003.The theoretical analyses and experimental researches are given.The equivalent moment factors of non-uniform bending beams,on various loading cases by finite element and finite difference methods are presented.From Chinese specifications of steel structures TJ 1774 to GB 500172003,the equivalent moment factor _b for the simply supported beam,under linear non-uniform bending,is adopted,which is its approximate minimum value and is derived by M.G.Salvadori,taken from L.Rayleigh,W.Ritz,method at 1956.The value _b is different from that in other specifications for design of steel structures.Referring the academic researches,a closed-form expression of calculating equivalent moment factor for any moment distribution and end support conditions is presented.This expression together with the revised flexural-torsional buckling design formula of beam may be provided for next cycle revision of Chinese Code for Design of Steel Structures.
- flexural-torsional buckling,
- equivalent moment factor,
- closed-form solution
