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.
