An investigation of seismic response of precast concrete beam to column connections: Experimental study

This paper presents the test results of three precast and one monolithic connection in moment-resisting concrete frame subjected to constant axial compression and lateral reversed cyclic loads. The precast specimens had cast-in-place concrete connections with different details, namely straight spliced (PC1), U-shaped (PC2), and U-shaped with steel plate (PC3).The results for Hysteresis loops, strength, damping, energy dissipation and ductility are presented. Comparisons of performance parameters revealed that the behavior of PC1 was more similar to monolithic Specimen and it can be used in high seismic zones. The other two precast connections are recommended to be used in moderate seismic regions.
