Prevention of Stress-Induced Failures of Prestressed Concrete Crossties of the Railroad Track Structure
| 项目名称： | Prevention of Stress-Induced Failures of Prestressed Concrete Crossties of the Railroad Track Structure |
| 摘要： | The problem the research team is trying to solve is to understand and mitigate premature failures of prestressed concrete crossties (PSCCs), which are an essential structural component of a railroad track structure. The objectives of the project are to identify the main mechanisms of horizontal cracks upon de-tensioning prestressing wires with respect to various geometrical/mechanical parameters and to develop more durable bonding mechanism between concrete and prestressing wires using engineered cementitious materials. |
