Abstract:

The use of precast concrete components in bents can accelerate bridge construction, but, their use in seismic systems is challenging. Such systems must have connections that are both easy to assemble on site, and have sufficient strength and ductility during earthquakes. A precast bridge bent connection, which uses a small number of large bars anchored in ducts, meets these requirements. Cyclic lateral load tests conducted on subassemblies of the system demonstrated that it has strength and ductility similar to those of a comparable cast-in-place connection. Intentional debonding of a short length of the bars had little effect on performance.
