Project Description

The proposed research aims to:

1) Characterize the behavior of UHPC structural members subjected to loading conditions similar to those experienced in the field for bridge foundations and micropiles by performing large-scale laboratory tests on different cross-sections of the structural members using structural laboratory facility at Iowa State Unviersity;

2) Evaluate the behavior of UHPC soil-pile system subjected to vertical and lateral loads by using full-scale field tests on piles/micropiles; and

3) Develop design methods and demonstrate potential use of UHPC in geotechnical applications.
