        abstract = {Large-span stadium roof structures are highly susceptible to dynamic and seismic effects, where structural performance is significantly influenced by roof geometry. This study focuses on the comparative analysis and optimization of steel truss stadium roof systems with different geometrical configurations, namely flat, inclined, and curved roofs. Parametric models of all roof types are developed and analyzed in STAAD.Pro as per IS 801:2005. Dynamic analysis is carried out using El-Centro earthquake time history data to evaluate important response parameters such as fundamental time period, displacement, member forces, and stresses. A comparative study is performed to identify the influence of roof shape on seismic behavior and structural efficiency. Further, a Java-based Genetic Algorithm (GA) is developed and implemented to optimize the roof structure by minimizing structural weight while satisfying design constraints related to stress, displacement, and safety requirements. The optimization results are compared for all roof configurations to determine the most economical and efficient stadium roof system. The study provides an integrated approach combining parametric modeling, dynamic analysis, and optimization for safe and cost-effective stadium roof design.},
