Comparison Of Double Warren And K-Type Steel Truss Bridge For Weight Subjected To Double Track Railway Loading
Keywords:
Truss, Double warren, K-typeAbstract
Steel truss bridges are widely adopted for railways in India for long span bridges (span > 30m). The most significant advantage of using trusses for bridges is that it allows us to span a considerable distance without creating a massive weight penalty for the structure. This design makes it possible to install a bridge in places where the volume of the structure impacts the surrounding environment.
In this paper comparison of Double warren truss is done with K-type truss considering weight of the truss. Span of the truss is 121.320m c/c and of depth 17m which is caring double track 25T railway loading.
