Abstract

The paper presents  the development of an optimum design of  linear plane steel trusses using heuristic method. Overall buckling as well as local buckling of members is considered. The design criteria followed the AISC 2010 specifications [1] using both the Allowable Strength Design (ASD) and the Load and Resistance Design (LRFD) method.  The proposed algorithm will select a possible minimum volume of the given plane truss and at the same time can safely carry all given loads. From the selected truss used in this study, it has been shown that the method can reduced the truss volume by about 2.58 percent when compare to the results obtained from the optimum design using genetic algorithm studied in the past [7]
