This work gives a thorough analysis and design optimization of Reinforced Concrete (RCC) girder bridges. The goal was to assess the bridge's structural performance under various loading circumstances, compare the findings produced from traditional manual calculations with the STAAD PRO programme, and recommend design optimization options to improve the bridge's performance. To examine the behaviour of RCC girder bridges, the research used a variety of analysis approaches, including finite element analysis, analytical methods, and numerical techniques. A comparison of the accuracy and dependability of traditional human computations against software-based analysis utilising the STAAD PRO programme was performed. The results revealed the benefits of adopting software-based analytical techniques in bridge design. When compared to typical manual calculations, the STAAD PRO programme produced more accurate findings for maximum moments, shear forces, and deflections. This demonstrates the dependability and effectiveness of software-based RCC girder bridge analysis methodologies. To improve the structural performance and efficiency of RCC girder bridges, design optimization procedures were presented. Geometry optimization, material selection, cross-sectional shape optimization, redundancy implementation, and the deployment of new structural systems were among the tactics employed. Each technique has the potential to increase cost-effectiveness, durability, and sustainability. The findings of the study contribute to the area of bridge engineering by offering useful insights into the behaviour and design optimization of RCC girder bridges. The study underlines the significance of precise analysis, software-based approaches, and design optimization tactics in assuring these bridges' structural performance and efficiency. More study is required to improve knowledge and optimization of RCC girder bridges. The goal is to create bridge designs that are safer, more efficient, and sustainable in order to fulfil the changing demands of transportation infrastructure.
