Most of the study carried out in the field of skew bridges is of theoretical nature and does not provide any direct help to engineers designing bridges specially, for Indian loading conditions. Therefore an effort was made to help such engineers in the quick calculations of design live load moments (LLM) for small span skew RC bridges. For these bridges of practical dimension and skew angle as used by design engineers in Indian conditions are selected for the study. Two lane RC simply supported T-Beam bridges with varying skew angle (0 0 to 40 0 at 10 0 interval) and varying span (12 m to 21 m at 3 m interval) were analyzed in STAAD PRO software using grillage analogy method. Two lane bridges mostly have three longitudinal girders and are simply supported on three bearings. The same has been used in the study. IRC vehicles (70R Tracked, 70R Wheeled and Class A as per IRC 6) are used to simulate loading conditions for Indian bridges. Effect of skew is observed on design live load moment at critical location (mid span region) in the girders and the same is presented in charts to ease the calculation. With an increase in skew angle, a reduction in design live load moment (LLM) was observed for outer longitudinal girders while, for middle longitudinal girder, design LLM was not much affected. This trend was observed for all spans from 12 m to 21m. This suggests that skew bridges designed ignoring the skew effects are conservative with respect to the bending moment.
