The Inelastic Analysis of Beam-Slab Highway Bridge Superstructures
The report describes an analysis scheme to predict the overload response of simple span beam-slab type highway bridges with reinforced concrete deck slab and reinforced or prestressed concrete I- or rectangular beams. The analysis scheme is based on completed research on reinforced and prestressed concrete beams, and reinforced concrete slabs, reported in 'The Inelastic Analysis of Reinforced and Prestressed Concrete Beams' by J.M. Kulicki and C.N. Kostem (Fritz Engineering Laboratory Report No. 378B.1, Lehigh University, 1972) and 'The Inelastic Analysis of Reinforced Concrete Slabs' by W.S. Peterson, C.N. Kostem and J.M. Kulicki (Fritz Engineering Laboratory Report No.378B.3, Lehigh University, 1974), respectively. For a full understanding of the contents of the reported investigation, a study of these reports is needed. The analysis scheme assumes that the superstructure can exhibit material nonlinearities while remaining geometrically linear. It is also assumed that the inelastic response of the superstructure is governed by the flexural behavior, i.e. excluding the effects of transverse and torsional shear. The developed scheme utilizes finite element displacement method, discretizing the superstructure into layered beam and plate bending elements. The method is compared against five full scale bridge tests. In all cases a good agreement was observed from the elastic regime up to the collapse of the super-structure. The presented method is intended to be employed by engineers as a tool to predict the overload response of the superstructures. Through the employment of the appropriate failure and serviceability criteria, policy decisions not investigated herein, the rating of the bridges for various overload configurations can be undertaken.
