Project Objective | The objective of the proposed project is to develop a practical bearing arrangement scheme for continuous steel-plate-girder highway bridges in infrequent seismic zones such as the Central and Eastern United States. |
| |
Project Abstract | The bearing arrangement shall be suitable to accommodate seismic forces while it allows for free thermal expansion, which is an essential ingredient for the design of bridges experiencing considerable thermal displacement. |
| |
Task Description | - Optimize the shape of the metallic dampers.
- Monitoring of one cracked and uncracked bridges.
- Development of a FEM model to investigate the serviceability and stress induced performance of a cracked bridge.
- Develop a design procedure for the proposed system.
