摘要：The FEA is carried out to analyze the skewed RC and PC single-span slab bridge decks and alsoexplored how the skew angle influences with respect to aspect ratio and live load i.e. IRC class A wheel load. TheFEA results of 15 RC and 15 PC skew bridge deck models are compared with right bridge for dead load and live loadcombination and variations in structure response parameters such as longitudinal B.M, transverse B.M, torsional B.M,and longitudinal stresses are observed with various skew angles and aspect ratios. The results show that with increasein skew angle, maximum longitudinal B.M decreases, maximum transverse B.M increase, maximum torsional momentincreases, and the maximum longitudinal stresses decrease with skew angle up to 30o, but increase thereafter. Theadvantage of pre-stressing shows significant decrease in longitudinal and transverse B.M and longitudinal stresses.
