Report on Structural Analysis and Design of Pedestrian Bridge in Urban Residential Area

Abstract

This executive summary provides a concise overview of the analysis conducted on two different bridge systems: a 4-girder deck system and a 2-girder deck system. The analysis was performed using the structural analysis software ETABS and verified with hand calculations. The objective was to determine the most viable option for the pedestrian bridge project. Based on the analysis results, it has been concluded that the 4-girder deck bridge system is more reliable than the 2-girder deck system. The 4-girder configuration demonstrated superior structural integrity and performance, meeting the design requirements and ensuring enhanced safety for pedestrians. Additionally, the substructure system, including abutment piers and other components, was calculated to support the chosen 4-girder deck system. These calculations were performed in accordance with the BNBC 2022 (Bangladesh National Building Code), AASHTO and PWD (Public Works Department) standards to ensure compliance with local regulations and guidelines. Furthermore, a comprehensive bill of quantity for the entire bridge project has been prepared. This bill of quantity details the required materials, quantities, and estimated costs for constructing the pedestrian bridge. Moreover, a project schedule has been developed, aligning with the BNBC 2022 and PWD guidelines. The schedule outlines the timeline for different project phases, including design, construction, quality control, and project completion. This schedule facilitates effective project management, resource allocation, and coordination among various stakeholders. In summary, the analysis conducted on the RCC Deck Girder Pedestrian Bridge project has determined that the 4-girder deck system is the preferred option due to its higher reliability. The project plans include the calculation of the substructure system, a bill of quantity for materials and costs, and a project schedule based on the BNBC 2022 and PWD regulations. These findings and deliverables provide a solid foundation for the successful implementation of the pedestrian bridge project.
