Application of Methacrylate Polymers for Seismic ABC Connections |
摘要: |
Previous research has demonstrated the validity and effectiveness of grouted ducts filled with advanced materials such as ultra high performance concrete (UHPC) for seismic accelerated bridge construction (ABC) column-to-footing and column-to-cap beam connections. Accordingly, State DOTs such as Caltrans considered this connection type in ABC pilot project in high seismic areas in California. This connection type was first demonstrated using robust proprietary UHPC mixes. Nonetheless, in an ongoing Caltrans project, University of Nevada, Reno (UNR) has developed non-proprietary UHPC mix for this specific connection type. Non-proprietary UHPC has also been demonstrated feasible and effective for this connection. However, recent concerns about domestic steel fibers availability and UHPC compliance with the Buy America act are motivating the need to find and validate the use of alternative materials that provide superior bond and anchorage behavior without relying on steel fibers. Polymer-based materials can provide a good candidate for this application, but more research is needed to identify best polymer-based materials and demonstrate its validity using large-scale testing. The aforementioned knowledge gap is the reason for undertaking this project. |
