摘要

The yield capacity curve of a steel channel section with a linear stress/strain distribution can be solved using the analytical approach illustrated in the author's two books on the subject. The variables considered are the dimensions of the channel section, the position of the capacity axis and the yield stress of the material. The free body diagram is drawn to indicate these variables and the line equations to define the sides of the channel section and the linear stress/strain function. The required equations are derived using only basic mathematics. From these equations the yield capacity curve which encompasses all cases of loading on the section is developed. This analytical procedure thus provides a solution without using the current standard interaction formula for biaxial bending. The numerical example showed that the analytical method of solution yields the most accurate and realistic result when predicting the true capacity of a channel section.
