Masters Thesis-Open Access
Conventional steel I-girder highway bridges utilize cast-in-place concrete deck. Maintaining the deck profile as per project specifications might be a challenging task. Deformation of girders and formwork used for deck placement need to be controlled during deck placement. Differential deflection between girders, exterior girder web out-of-plane deformation, exterior girder warping, or a combination thereof could impact the deck profile. These deformations challenge maintaining deck profile and need to be considered as a part of constructability evaluation. Determining deck profile due to potential girder deformations is necessary before deck placement so that the remedial actions can be implemented when deck finish tolerances are violated. For non-complex steel I-girder bridges, cost- and time-effective procedures are needed for this evaluation. Simplified analysis tools were adopted and modified to analyze girder differential deflection and exterior girder warping. A procedure was developed to address the effect of web out-of-plane deformation on deck profile and demonstrated using an example. Remedial measures were suggested for maintaining the intended deck profile.
