Abstract: Design and evaluation of prestressed concrete I-girder bridges is in large part dependent on the transverse load distribution characteristics and the dynamic load amplification, as well as service level, live load, and ...

Abstract: Integral abutment bridges (IABs) are now a routine construction and design of choice for many DOTs as bridges are replaced or for new roadways. However, current design and analysis methodologies have not matured substantially ...

Abstract: The objective of this project is to evaluate the cumulative damage caused by vehicle loading to bridge concrete deck slabs. As part of this study, an existing analytical model has been implemented to evaluate the effect ...

Abstract: Past research has been conducted on the behavior of horizontally curved girders by testing scaled models and full-scale laboratory bridges and by analyzing numerical models. Current design specifications are based on this ...

Abstract: A fatigue-live-load model is developed for steel girder bridges. The database for the model is obtained by weigh-in-motion (WIM) measurements. Five bridge structures were selected for testing to determine the site-specific ...

Abstract: This project examined several uncertainties of integral abutment bridge design and analysis through field-monitoring of an integral abutment bridge and three levels of numerical modeling. Field monitoring data from a ...

Abstract: The present study is designed to determine the effect of major parameters on maximum total bending moments of curved girders, establish the relationship between key parameters and girder distribution factors (GDFs), and ...

Abstract: Dowel and stiffener beam deck-to-deck connections transfer shear and moment between hardwood glued-laminated (glulam) transverse deck panels in longitudinal timber bridges. The connections resist relative deflections between ...
