TO STUDY THE RESPONSES OF BRIDGE DECK FOR VARIOUS SKEW ANGLES

 The objective of this study was to understand the meaning of skew bridge. To know the behavior of skew deck. In this work, the effect of change of skew angles for right bridge deck is studied by finite element method. Bending moment, support reaction and torsional moment are computed by using FEM in CSI BRIDGE and results are compared for different skew angles. Simple supported single span bridge deck is considered for this study. The results by analysis shows that as the skew angle increases, support reaction increases, but bending moment decreases and torsion moment also increases. The effect of skewness on the behavior of bridge deck is studied for skew angle 15°, 30° and 45° and presented graphically using FEM method. Results are presented for analysis method for dead load and live load
