Comparative Study on Analysis and Design of Skew Bridge by STAAD and ETABS Software using Finite Element Method

Skew bridges are required to cross the drains at any angle other than normal. These can be helpful in making straight crossing or utilizing the available land where normal crossing are either impossible or not suitable. The slab bridges are uneconomical for large spans due to excessive design thickness but good for small spans due to its easy execution.Bending Moment result comparison between both software i.e. Staad Pro and Etabs show little variation For Span 15 m on Staad Pro and Etabs is 74.518 kn sq.mm and 68.40kn sq.mm respectively, For Span 17 m on Staad Pro and Etabs is 71.47 kn sq.mm and66.70 kn sq.mm respectively and For Span 19 m on Staad Pro and Etabs is 79.73 kn sq.mm and71.95 kn sq.mm respectively. At constant skew angle for varying span length the torsional bending moment gradually shift toward obtuse acute angle. In both the software i.e. STAAD and ETAB the ETAB give more appropriate result in compare to STAAD.
