چکیده: Two types of precast and one type of monolithic full scale beam-column connections are tested

under reversed cyclic loads. Both of the precast concrete connections tested were cast in place,

but with different connection details, namely straight spliced (PC1) and U-shaped (PC2). The

straight spliced and U-shaped connections were located in the beam and column of the precast

concrete subassemblies. Hysteresis response, strength, stiffness, damping and energy dissipation

of monolithic and precast connections were studied and then compared together. Monolithic

specimen (MO) indicated a good behavior in terms of integrated seismic parameters. The

experimental results shows that Specimen PC1 in which the top and bottom reinforcement are

continued by lap splicing treated a good behavior very similar and closed to those of control

monolithic specimen and preformed very good based on seismic demand. The behavior of

Specimen PC2 that U-shaped rebars were used in its connection was not satisfactory in

comparison with other specimens. Some shear deteriorations observed in both PC1 and PC2

connections. As conclusion, connections PC1 and PC2 are suggested in precast moment

resisting frames with moderate ductility located in high seismic zones. However, some essential

practice-oriented modifications are required.
