Abstract

The long-term behaviour of an exterior precast concrete beam-column (PCBC) connection has been investigated in this study. The connection consists of a precast U-beam, precast column with corbel, and interlocking bars to connect the precast column and precast beam. The specimen was tested under sustained loading for 120days. The crack propagation, the development of strain and the deflection of the beam was observed throughout the test. The results show that the PCBC connection behaved in similar manner to correctly designed conventional reinforced concrete members under long-term loading. Flexural cracks occurred within the plastic hinge region of the beam. No cracks occurred in the joint core and column. The long-term behaviour of the PCBC connection was influenced by shrinkage and creep. The significant increase of deflection occurred in the first 15 days of testing, which is 37% of the total long-term deflection. The experimental long-term deflection has bigger value than the theoretical deflection evaluated using ACI 318-08.
