| Abstract: | In order to meet the needs of the practical structural design, the quick determination method of cross size of H-shaped wide-flange steel beam-column member is investigated and presented. The key point of the method is to represent each section parameters with cross section height h , and to describe the strength and stability conditions as functions of one variable——the section height. Then finding the zeros of the strength and stability equations of steel members through bisection method etc., then the root of the equation will be the required section height, through which the section size and corresponding size number of the formed steel beam-column member will be easily and quickly given. |
