Abstract:
Experimental results from six full-scale beam-column subassemblies showed that eccentric corner joints connecting spread-ended beams, which have enlarged beam width and modified reinforcement details in the region near the joint, can result in superior seismic performance compared with those eccentric corner joints connecting ordinary beams. Accordingly, guidelines including the determination of effective joint width for eccentric corner joints connecting spread-ended beams and the determination of geometry and reinforcement details for spread-ended beams are provided. Also presented in this paper is the effect of eccentricity on the hoop strain distribution of corner joints.
