Experimental Investigation on Seismic Response of Bridge Pile Foundation
A pile bridge is a structure that is supported by numerous long piles of wood, concrete, or steel that are pushed into the soils beneath the bridge until they eventually reach a hard stratum of compacted soil or rock. An extremely significant component impacting the performance of the structure is the behavior of pile foundations under seismic load. Bridges supported by piles have sustained serious damage in a number of earthquakes across the world. In meizoseismic locations, recently designed bridges with a large width, greater bearing capacities, and superior seismic activity have been adopted, although these bridges have sustained damage during earthquakes. Ring cracks, pile cracks in concrete, and even complete failure during an earthquake are all examples of seismic damages. Seismic response of bridge pile foundation was carried out on soil in the laminar shear box by using shake table tests. For this purpose, a model concrete pile with pile cap in sand bed was tested. After the preparation of sand bed along with concrete pile and superstructure, model tests were conducted using shaking table. The frequency and amplitude of the shaking table was set to the required values. Displacements, accelerations, and strain during the tests were recorded using sensors provided at desired locations. Experimental investigation shows that when the frequency and amplitude of vibrations increases, acceleration of pile, displacement, and strain increases.
