Research of road bridge composite steel girder for different load conditions

Abstract

A bridge structure is a mean by which a road, railway and many other services are carried over an obstacle such as a valley, river and other road or railway line, either with few number of supports at various locations or with no intermediate support. While finalization of any types of bridge; Economy, Strength, Safety are the basic key features that cannot be neglected in the construction of any bridge. However the Indian standards are basically derived from the British Standards only, but the basic concept behind that is same. Only the value of various parameters varies according to the design and fabrication/ erection practices which exist in India. In this paper a plate girder bridge is designed as per the Limit state method using the IS 800:2007, IRC: 24-2000, IRC: 6-2017 and analyzed with the help of STAAD.pro v8i software. Modeling and analysis of Deck Bridge was carried out by considering various live load conditions such as for Class A loading, 70R tracked and 70R wheeled vehicle. Design calculations are carried out for simply supported single span. Seismic and wind effects are not taken into account at the design stage. Based on the design and analysis results, conclusions are drawn to know the behavior of plate girder bridges for different load conditions. Results are presented in both graphically and tabular format.
