Abstract

An algorithm for optimum minimum-weight design of built-up wide-flange sections for flexural steel members is presented. The formulation comprises a general solution subject to compact-section and strength constraints. The design is based on the allowable stress procedure of the American Institute of Steel Construction (ASD-AISC) specifications. The optimum solution is of closed- form so that the section proportioning is direct and simple. The solution is governed by activeness of moment alone or moment and shear together. The process is illustrated with the help of an example problem which is implemented on a spreadsheet. 1 Introduction Doubly symmetric built-up wide-flange (BWF) steel beams become practical for cases where the required flexural capacity exc
