Vehicle Collision Impact Response of Bridge Pier
Strengthened with Composites
Tesfaye Alemu Mohammed, Ph.D.1; and Azadeh Parvin, D.Sc.2
Abstract: Shortening delays for immediate access to essential public infrastructures when subjected to rare extreme loadings are critical to
promptly normalize socioeconomic

Studies on vehicle collisions with bridge compo-
nents are limited. Additionally, few researchers have investigated
the use of FRP composites to strengthen bridge girders damaged
by vehicular impact.
Saini and Shafei (2017) showed use of CFRP to improve pier
behavior against vehicular impact load.

Dynamic impact force versus time history plot is a critical
response in quantifying structural force demand during vehicle
bridge pier collision. Fig. 7 presents Chevy C2500 dynamic force
versus time history. More rigid vehicle components caused spikes
on the dynamic force time history plot.
