SEISMIC BEHAVIOR OF PRESTRESSED CONCRETE BEAM-COLUMN JOINTS

The experiment on prestressed concrete beam-column joints was designed to investigate the effect of concrete strength and design code on seismic behavior of such joints. The major design parameters varied in the specimens were the concrete strength (high versus normal strength concrete) and the design code (AASHTO versus New Zealand codes). From the test results, it was concluded that both the AASHTO and New Zealand Codes provide sufficient capacities for earthquake-design, and before spalling of the concrete cover, the stiffness degradation of the specimen with high strength concrete was less serious than that with normal strength concrete. However, when the concrete cover spalled, more stirrups were needed for the specimen with high strength concrete.
