Rapid Repair and Retrofit of Timber Piles Using UHPC
| 项目名称： | Rapid Repair and Retrofit of Timber Piles Using UHPC |
| 摘要： | This project proposes the use of ultra high performance concrete (UHPC) as repair and retrofit material for timber piles, however, many research questions should be answered such as the bond strength between timber and UHPC, the surface preparation for timber piles to enhance the bond strength with UHPC, the effect of UHPC thickness of repair/retrofit. These questions, among others, will be answered under this project. The objectives of this research project are: (1) Studying the bond strength between timber and UHPC as repair/retrofit material; (2) Defining the best surface preparation for timber piles in order to enhance the bond strength; (3) Studying the load-carrying mechanism of timber piles repaired or retrofitted using UHPC; (4) Conducting small scale testing to study the bond strength and load-carrying mechanism between timber and UHPC; (5) Conducting large scale component testing of timber piles repaired/retrofitted using UHPC under realistic axial and lateral loading schemes; (6) Studying repair methods for in-service weathered piles; and (7) Developing detailed finite element models for both small scale material testing and large scale component testing for better understanding of the local and global behavior of timber piles repaired/retrofitted using UHPC. |
