Abstract

The limited strong earthquake database on structure and pile performance obstructs obtaining further progress in soil-pile structure interaction problem. Model test in laboratory is one of the best ways to expand the database of structure and pile performance during earthquake. In this paper, the problem of pile-soil-pier-structure interaction is investigated by shake table test approach, and on the development of the sandy box for SPSSI test is firstly introduced. Through free field test, the validation of the model container was evaluated by comparisons of soil acceleration records with those numerically calculated by SHAKE91. Secondly, four specimen to simulate friction pile response were employed: single column pile pier, one column pier model with 2x2 piles, two-column piers model with 2x2 piles and two-column piers model with 3x2 piles. The characteristic behaviors of single pier and two piers were comparatively experimented and analyzed under the same condition of pile groups and input motion.

Shaking Table Tests of Seismic Pile-Soil-Pier Structure Interaction

San Diego, California

The limited strong earthquake database on structure and pile performance obstructs obtaining further progress in soil-pile structure interaction problem. Model test in laboratory is one of the best ways to expand the database of structure and pile performance during earthquake. In this paper, the problem of pile-soil-pier-structure interaction is investigated by shake table test approach, and on the development of the sandy box for SPSSI test is firstly introduced. Through free field test, the validation of the model container was evaluated by comparisons of soil acceleration records with those numerically calculated by SHAKE91. Secondly, four specimen to simulate friction pile response were employed: single column pile pier, one column pier model with 2x2 piles, two-column piers model with 2x2 piles and two-column piers model with 3x2 piles.
