| Summary: | A modified assembled configuration is introduced for precast
concrete frames in which the connections are constructed on the
beam span and kept away from the column faces so as to avoid
coinciding with the plastic hinge regions during seismic excitations.
An experimental study on the seismic performances of two fullscale
precast concrete subframes adopting the aforementioned
configuration and a monolithically-cast subframe subjected to
quasistatic simulated seismic loading is presented. The variable
examined was the connection detail. The performances of the
precast concrete frames are evaluated on the basis of ductility, energy
dissipation capacity, connection strength, and drift capacity. Based
on the test results, the precast concrete frames are capable of
matching overall performance of the monolithic connections and
thereby providing moment-resisting behavior. |
