Experimental And Analytical Study Of Dynamic Behavior Of Bridge Superstructures Subjected To Overheight Vehicle Collisions, Yuan Jing
Doctoral Dissertations
The increasing occurrence of over-height vehicle collisions with bridges in the United States leads to concern about the damage due to lateral impact to bridge superstructures by over-height vehicles. However, this issue is not fully addressed in current bridge specifications. Previous researchers have conducted a number of small-scale tests to study the impact process. Also, finite element method (FEM) has largely been used to analyze the complicated collision mechanism.
A full-scale lateral impact testing facility was designed and built on a construction site in Knoxville, Tennessee, United States. An AASHTO Type-I prestressed concrete (PC) girder and a Hybrid Composite Beam …
