Dynamic Field Tests of Small-scale Bridge Bents Supported on Drilled Shafts

Published on


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.

Finally, the hydraulic shaker from the small NEES mobile shaker, Thumper, was
attached to the bent cap and used to excite the specimens harmonically. The
measured frequency response of the test specimens is summarized in this paper.
