This paper introduces a multi-objective optimization approach for planar steel truss structures, employing the RDMO algorithm-a hybrid of Rao-1 algorithm and differential evolution (DE). The study focuses on two primary objectives: minimizing total weight reducing lateral displacement at apex, with design variables defined as cross-sectional areas members within specified range. Direct analysis is implemented to accurately simulate nonlinear behavior structure evaluate its maximum load-bearing capacity under realistic conditions. A 10-bar selected case illustration. results demonstrate that effectively eliminates complex control parameters while achieving balanced trade-off between convergence speed, high accuracy, solution diversity. By enhancing mutation strategy non-dominated sorting crowding distance techniques, exhibits superior performance in improving design, offering significant potential widespread applications modern civil engineering.
