Abstract

In this paper, we present an evaluation of the potential risk of earthquake-induced damage to pile foundations in Indiana. Piles are commonly used in foundations of bridge piers in the southern part of Indiana; the potential seismic sources in this region are the Wabash Valley Fault system and the New Madrid Seismic Zone. Based on in-situ test data for specific sites in southern Indiana, one-dimensional wave propagation analyses are performed. Additionally, the liquefaction potential is estimated based on the calculated acceleration profile. Data on real cases of pile damage due to seismic events are collected after an extensive literature survey. Using this information, the main causes and characteristics of earthquake-induced pile failure are identified, and the conclusions obtained are applied to southern Indiana to make a preliminary assessment of pile damage potential. Simple 3-D numerical analyses for the pile foundations of an existing bridge structure are performed using the finite element method. The results show that, for typical pile foundations and soil profiles in southern Indiana, a credibly large earthquake is capable of producing significant damage to the piles.

Seismic Design of Pile Foundations in Southern Indiana
