Abstract
Due to technological advances, efficient structural systems are increasingly required in modern industries. Many industrial buildings, such as warehouses, hangars, fire stations, and sports halls, are designed with large spans and non-flat roofs, often sloped or curved. This paper presents a comparative optimal design of steel truss sheds with two roof types (sloping and curved) and two column types (rectangular and circular). The Enhanced Colliding Body Optimization (ECBO) algorithm is employed, offering a balanced mechanism of exploration and exploitation, which improves efficiency compared to algorithms like PSO and GA. The design process follows AISC specifications, considering stress, displacement, and slenderness limitations. Structural members are modeled with discrete cross-sectional variables, and the trusses are analyzed under dead, live, snow, wind, and earthquake loads. Results indicate that the truss with a sloping roof and rectangular columns achieved the minimum weight while maintaining uniform stress distribution. This configuration demonstrated superior structural performance regarding strength and serviceability, highlighting its suitability for industrial applications. Overall, the findings emphasize the role of optimization methods in enhancing structural efficiency and provide guidance for the practical design of lightweight and resilient steel sheds.
