To better understand the behaviour of curved box girder bridges in resisting eccentric design truck loads, and the influence of plan curvature on the structural response, a model study was conducted at the University of Ottawa. In this study, the elastic response of a curved composite box girder bridge model was evaluated experimentally and confirmed analytically using the finite element method. Analytical predictions of both vertical displacements and normal stresses at critical sections compared fairly well with those evaluated experimentally. The isoparametric thin shell element employed in the analysis proved to be versatile and provided an accurate representation of the various structural components of a curved box girder bridge. Despite the eccentric nature of the applied OHBDC design truck loads and the bridge plan curvature, it was evident that in resisting the applied live loads, the girders at critical sections share equal proportions of the applied bending moments.

Studies on ultimate limit states and nonlinear behaviors of bridges will greatly enhance the understanding of bridge engineers on the moment and shear distribution and the general performance of bridges under load. Described herein is an experimental and theoretical investigation of ultimate loads and nonlinear behaviors of two-span continuous composite curved multi-cell box-girder bridges with a single column as middle support and subjected to OHBDC design truck loadings. The curved bridges are modeled by using the finite element methods. The deck slab, webs, the bottom plate and diaphragms are modeled by 4-node shell elements while the shear connectors and the single middle column are modeled by 3-D beam elements. The existing software COSMOS/M is used for the analysis. A model test of a two-span continuous composite curved multi-cell box-girder bridge with a single column at the middle support is conducted to verify the finite element method. Idealized bridges with different parameters are also studied. Consideration is given to many of the variables that significantly influence ultimate loads and nonlinear behaviors of such bridges. Several rational suggestions are made to enhance the design of two-span continuous composite curved four-cell box-girder bridges.

The Texas Department of Transportation designs typical highway bridge structures as simple span systems using standard precast, pretensioned girders. Spans are limited to about 150 ft due to weight and length restrictions on transporting the precast girder units from the prestressing plant to the bridge site. Such bridge construction, while economical from an initial cost point of view, may become somewhat limiting when longer spans are needed. This project focused on developing additional economical design alternatives for longer span bridges with main spans ranging from 150-300 ft, using continuous precast, prestressed concrete bridge structures with in-span splices. Phase 1 of this study focused on evaluating the current state-of-the-art and practice relevant to continuous precast concrete girder bridges and recommending suitable continuity connections for typical Texas bridge girders; the findings are documented in the Volume 1 project report. This report summarizes Phase 2 of the research including detailed design examples for shored and partially shored construction, results of a parametric design study, and results of an experimental program that tested a full-scale girder containing three splice connections. The parametric design study indicated that for bridges spanning from 150-300 ft, continuous precast, prestressed concrete girder bridges with in-span splices can provide an economical alternative to steel girder bridges and segmental concrete box girder construction. The tested splice connections performed well under service level loads. However, the lack of continuity of the pretensioning through the splice connection region had a significant impact on the behavior at higher loads approaching ultimate conditions. Improved connection behavior at ultimate conditions is expected through enhanced connection details. Recommendations for design of continuous spliced precast girders, along with several detailing suggestions are discussed in the report.
