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.
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.
process is illustrated with the help of an example problem which is
implemented on a spreadsheet.
Doubly symmetric built-up wide-flange (BWF) steel beams become practical
for cases where the required flexural capacity exc...
