Industrial steel buildings are widely used in construction projects due to numerous advantages such as cost savings, fast time, large span capability, and better suitability for large-scale production storage purposes. Due the characteristics, column beam sections industrial often use composite steel, where dimensions of reasonably designed ensure both structural performance efficiency. However, with complex design variables, selecting appropriate sizes poses a challenging problem. In this paper, we introduce modern method address issue by setting up an optimization problem determining optimal cross-sectional frame buildings.

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.
