Dynamic Field Tests of Small-scale Bridge Bents Supported on Drilled Shafts
Two, 1/4-scale, two-column, bridge bents were constructed at a field site in Austin, TX. Three different types of dynamic tests were conducted. Initially, the specimens were struck with a modal hammer to induce low-amplitude, free-vibration response. The large NEES mobile shaker, T-Rex, was used to induce harmonic vibrations in the test specimens by exciting the surface of the ground.
