Dynamic response analysis of stiffened slab bridges

The dynamic response of skew bridge decks with stiffeners has been investigated using higher order finite strip method. The eccentricity of the stiffeners is also considered in the analysis. Normal mode method in conjunction with William's method to accelerate the convergence of the solution has been used to find the dynamic response of the bridge deck due to moving load. The influence of eccentricity of stiffener on the deflection and bending moments in the deck, and bending moment in the beams, has been investigated. Numerical work has been presented for different skew angles and the speeds of the moving force. © 1978.
