Abstract
Bridges serve as elevated pathways that allow for uninterrupted travel over obstacles while maintaining the alignment of the underlying road or pathway. This study focuses on the design of I-bridge girders, specifically longitudinal and cross girders. The bridge in question has a span of 22m, and the girders are constructed accordingly. The longitudinal girders have dimensions of 1800 1000 mm, while the cross girders measure 1800x1000 mm. The bridge consists of four longitudinal girders spaced at 3000 mm cc, and four cross girders. The design of these girders is carried out using the CSI Bridge software. Two identical models are created in CSI Bridge for the purpose of this study, with loadings adjusted to comply with IRC codes and AASHTO-LRFD specifications, respectively. By applying these different loadings, the shear force, bending moment, and average rotation in both the longitudinal and cross girders are determined. The analysis is conducted using the CSi Bridge model, and the results are compared with relevant tables.
