Nomograms for Determination of Effective Length of the Unregular Frames Based on Mechanics and Steel Structure

Abstract:

Determining the frame column effective length is a key part of the structure stability calculation in practical engineering. This specification for design of steel structure and specification for design of concrete are given in some relevant calculation formula and forms, but these formulas and tables can only be applied to the simple situation. In the complex situation, such as the frame column axial force and height is large, the formula is not applicable, may leads to unsafe results. In this paper. the formulas are deduced by using second-order displacement method in order to solve these problems,and the chart for determining the effective length is also obtained. The chart can be used to calculate the effective length factor quickly and concisely.
