COMPARATIVE STUDY ON NORMAL AND SKEW BRIDGE OF PSC BOX GIRDER

Pranathi Reddy, Karuna S

Abstract: Nowadays the demand for high skew bridges has increased, and many bridge decks are built with some form of skew. The behavior of bridge is effected considerably with the presence of skew angle in bridge decks. In the present study an attempt has been made to study the skew bridge comparing with the normal bridge for skew angle 10, 20, 30, 40, 50. The finite element analysis is carried out for single span, two span and three span deck for dead load and moving load (IRC class 70R) loading using software SAP2000 ver.14. The results are presented in terms of displacement, bending moment and shear force.
