Abstract
The use of steel-fiber reinforced concrete to improve the behavior of beam-column joints during earthquake excitation is investigated. Results of quasistatic tests on three full-scale interior beam-column joints and part of a prototype building designed according to the National Building Code of Canada are presented. The first specimen was made of normal concrete but ignored the special seismic recommendations related to the spacing of lateral reinforcement in the beams, column, and joint. The second specimen was also made of normal concrete and included full seismic details. The third specimen was similar to the first one but incorporated hook-end steel fibers in the joint region. Experimental results indicated that steel fibers bridging across cracks in the concrete mix increase the joint shear strength and can diminish requirements for closely spaced ties.
