| Abstract | Beam-column precast connections are important role in determining the successful of precast concrete frame structures. The understanding on the behavior of the beamcolumn precast connection can be assessed by conducting experimental tests. This study presents the test of full scale four specimens, two beam-column monolithic connection specimens and two beam-column precast connection have different details of the height of beam. All of beam-column connection specimens were tested under reverse cyclic loading applied at the end of the beam by displacement-controlling. The precast connections considered where beam is connected to column using steel sliding in side direction. The experimental results of beam-column precast connection specimens have been compared with the beam-column monolithic connection specimens. The both specimens have same the behavior of failure mode, for the long specimens fail by the flexure failure and the short specimens fail by the flexure-shear failure including pinching effect. However, the beam-column precast connection specimens also have effect of bar buckling. Moreover, the nonlinear region of precast specimens move up from interface area when compared to the monolithic specimen. The performance of side-installation beam-column precast connections in terms of the load-displacement hysteresis behavior, maximum load carrying capacity, energy dissipation, stiffness degradation and ductility ratio were compared the monolithic beam-column connection. The precast specimens were found to perform better when compared to the monolithic specimens in terms of strength development and the maximum load carrying capacity. The both specimens showed almost same stiffness degradation and energy dissipation until the final stage at 5.00% drift ratio. For the final stage, the precast specimens showed lower stiffness degradation and energy dissipation due to bar buckling effect. In term of ductility ratio, the monolithic specimen was found to perform better when compared to the precast specimens. |
