Abstract:

The research conducted in this project was undertaken to gain insight into the load path and intensity of the longitudinal braking force in highway bridge substructures, specifically shorter span, simply-supported bridges. To evaluate braking force magnitude and distribution, two types of field tests were conducted static tests and dynamic braking tests. From these field tests, the data was processed and an analytical model was created and calibrated. The last component of the research project was a limited parametric study which further studied the distribution of the longitudinal braking force in substructure elements for simply supported spans typical in Alabama. The research demonstrated that the abutments will experience a maximum of approximately 75 percent and an individual column bent will experience a maximum of about 35 percent of the braking force. The demand in an individual component is related primarily to the position of the braking vehicle component and the relative stiffness of that component.
