Comparative Study on Concrete Box Girder (Single & Double Cells) Bridges Using Finite Element Method

Pampana Geetha Ramesh | Dr. P. V. Surya Prakash

Abstract: Bridge construction today has achieved a worldwide level of importance. Bridges are the key elements in any road network and use of reinforced girder type bridges gaining popularity in bridge engineering fraternity because of its better stability, serviceability, economy, aesthetic appearance and structural efficiency. Generally for long span Box girder bridges are more structural efficient. Box girder resists the torsional rigidity and suited for significant curvature. For this study, Four different bridge girders are considered namely Rectangular Single and Double cell Box Girder (RSBG & RDBG), Trapezoidal Single and Double cell Box Girder (TSBG & TDBG) of spans 20 m, 30 m, 40m and 50m. Linear Static and Modal Analysis are performed on all the considered bridge girders using SAP2000 bridge wizard. IRC Class AA Tracked Loading system is considered for the analysis. A comparative report on dynamic Characteristics of all the considered bridge girders using SAP2000.

Keywords: Stiffness, modal analysis, Linear Static analysis, Loading system, Dynamic Characteristics
