| A parametric study of Simply Supported 2-Lane Reinfroced Concrete T-Beam Bridges has been performed in STAAD PRO. The parameters varied were span and skew angle. The effect of same was observed on Maximum Live Load Bending Moment, Maximum Live Load Shear Force and Maximum Live Load Reaction at critical locations in terms of Moment Distribution Factor (MDF), Shear Coefficients and Reaction Coefficients. Live Load ¿Class 70 R Tracked¿, ¿Class 70 R Wheeled¿ and ¿Class A¿ are applied as per IRC 6:2000 guidelines. The spans used were 12 m, 15 m, 18 m and 21 m. The skew angles were taken at an interval of 10 degree starting from 0 degree up to a maximum of 40 degrees. Bridges with skew angle more than 40 degree are rare. Design tables are provided at the end along with case studies for quick understanding and estimation of design values. |
