Abstract Details

2020, Master of Science, University of Toledo, Civil Engineering.
Bridge has a lot of components that make the structure function properly. One of the main components of a bridge is the bridge bearing. The bridge bearings transfer the loads from the superstructure to the substructure. Along with the transfer of loads, it also permits rotation and deflection during load application in order to make the bridge function properly and prevent the structure from failure. Since bridge bearings are so important to a bridge structure, its behavioral study needs to be done. There are several researches done by the Transportation Research Board regarding stiffness studies on bridge bearings. But limited number of studies of Disc Bridge Bearings is done. There is very less data available for the compressive and rotational stiffness of a disc bridge bearing. The elastomer generally used in the disc bridge bearing is a polyether urethane pad. So, in this research, compressive stiffness of the polyether urethane has been calculated using the finite element analysis software Abaqus. Pressure is applied on top of the polyether urethane bearing pad with the objective of finding its behavior. Circular and annular pads are modeled and the dimension for the pads were varied for the parametric study. Along with the finite element analysis, the closed form solution has also been done and checked with the analytical results. Through this research, the failure mechanism and the strength of a polyether urethane bearing pad can be found out. The application of different pressure in the pad helped to verify the weak elements of the pad and the mechanism of collapse. This study can be implemented to understand the behavior of a polyurethane bridge bearing pad so that the bridge engineer avoids damage in the bridge bearing.
