| Abstract: | The aim of this work is to minimize the weight of steel
bridge trusses under the limitations imposed on its behaviour by the design
codes when it is subjected to moving load (HS20-truck). Adaptive manner
operators are included to enhance the capability of GA. Design examples are
solved to illustrate the applicability of proposed algorithm. Results are
compared with those evaluated by various optimization methods with continuous design variables such as sequential convex programming (SCP),
sequential quadratic programming (SQP) and evolution strategy (EVOL). It can be
concluded that the results obtained by GA is meaningful, more suitable for
practice and GA performs well to find minimum weight of the bridge trusses
under moving load. |
