Computer Modeling Analysis in Bridge Evaluation. Phase 2. Dynamic Response of Continuous Beam Bridges and Slant-Legged Rigid Frame Bridges
This is an interim report of the second year's work on computer modeling analysis in highway bridge evaluation. The objective of this investigation is to study the dynamic and impact characteristics of continuous beam bridges and slant-legged rigid frame bridges due to vehicles passing over rough bridge decks. According to the Type 3, Type 3S2, and Type 3-3 trucks, three nonlinear vehicle models with nine, sixteen, and eighteen degrees of freedom are developed. Six continuous multigirder bridges with different span lengths are designed based on the Standard Plans of Highway Bridge Structures of U.S. Bureau of Public Roads. The continuous multigirder bridges are modeled as grillage beam systems. The effect of transverse stiffness, road surface roughness, vehicle speed, span length, spacing of girders, and damping ratio are analyzed. The slant-legged rigid frame bridge is modeled as a space bar system. The free and force vibration characteristics including parametric study are analyzed.
