Abstract

Abstract

Section geometric properties of channels with different bending degrees of inclined simple edge stiffeners are gained by calculation. It is convenient for solving the buckling stress by hand. The test strengths and failure modes reported by an experimental reference of axially loaded fixed-ended channels with inclined simple edge stiffeners are compared with the strengths predicted using direct strength method. It is shown that direct strength method is valid for predicting the stability capacity of axially loaded fixed-ended channel columns with inclined simple edge stiffeners, consequently it is indicated that direct strength method which was developed based on the regression of pin-ended tests results is also applicable for calculating the stability capacity of fixed-ended columns.
