Abstract: 
Concrete frame joint is an important portion, which affects seismic behavior of whole structure. The general way improving the joints' ductility is enhancing the ratio of enforcing steel bar in joint core area; however, it may result in some disadvantages. One way ensuring a joint's ductility is joining fiber into connection area. This paper introduces the studies on experiments of 4 high-performance PVA fiber toughened concrete column-beam exterior joints. Different volume ratios of fiber are considered. The joints are endured low-cycle repeating load on beam-end. The experimental results indicate that as PVA fiber joining into concrete the initial cracking load, the utmost load have a distinct enhancement even though the ratio of enforcing steel bar is low. Respectively, displacement behaviors are improved. It could be concluded that the ductility of PVA fiber joints is better than common one.
