Determining the Effective Length of Frame Column in the Action of the Fore with Variable Directions

Abstract:

Steel structure is designed by limiting condition generally. Checking its stability is important in design. Calculating the effective length of the column is a key of stability checking. Some charts and formulas are written on Code for Design of Steel Structures, which is not applicable to the structural systems because of some assumptions. What is more, finding some values is not easy and the trend of the values is not obvious. In the paper the effective length of the column in the action of the fore with variable directions is derived by the equilibrium condition method and the effective length of the column chart is also drawn. Using these charts can quickly determine the effective length, and there is an intuitive tendency which the effective length varies with parameters.
