Seismic Performance of Grouted Couplers with No Pedestal (GCNP) Column Connections in Accelerated Bridge Construction Applications in Idaho

This project will focus on the seismic performance of grouted coupler with no pedestal (GCNP) type column-to-footing and column to bent cap connections under Idaho seismic conditions. The performance of the GCNP connections will be compared to conventional cast-in-place connections. The main objective of this research project is to develop sections for the Idaho Bridge Design Manual showing acceptable application of GCNP connections.
