| Abstract: | Five specimens of beam column connections with modified enlarged beam width were tested under reversed cyclic loading. Experimental results showed that eccentric joints connecting spread ended beams, which have enlarged beam width with inclined reinforcement, can result in superior seismic performance. The comparison of crack patterns, the energy dissipation and the stress distribution in stirrups among those eccentric joints connecting spread ended beams with modified enlarged beam width are provided. Also presented in this paper is the stress distribution of inclined reinforcement and straight reinforcement in the enlarged portion of the beams with modified enlarged beam width. The suitable enlarged beam width is also proposed. |
