Seismic Performance and Assessment of Precast Beam-Column Corner Joint Subject to Reversible Lateral Cyclic Loading

A seismic performance of full-scale precast reinforced concrete beam-column corner joint with corbel was examined in the laboratory. The precast beam-column joint designed using BS8110:1:1997 was tested under lateral cyclic loading up to +1.5% drift. Displacement ductility of precast beam-column joint with corbel was determined. The visual observation showed that the damage occurred at the corbel of beam-column joint. Major cracks were also observed at the cast-in-place area above the joint area. In this paper, the damage state of the specimen is categorized in accordance to HAZUS®99 and the vulnerability of the specimen was assessed using fragility curve.
