Anchorage Performance of GFRP Headed and Bent Bars in Beam-Column Joints Subjected to Seismic Loading
Publication: Journal of Composites for Construction
Volume 22, Issue 6
Abstract
Concrete slabs, beams, and columns reinforced with glass fiber-reinforced polymer (GFRP) reinforcement have shown considerable deformability under monotonic loading; however, they have not been fully investigated under seismic loading. In efforts to understand the seismic behavior of GFRP-reinforced concrete (RC) moment-resisting frames subjected to seismic loading, this paper presents an investigation of the anchorage of GFRP bars in exterior beam-column joints. Four full-scale exterior beam-column joints were tested under cyclic reversed load simulating seismic loading conditions. Parameters tested in this study included end anchorage details of beam bars in the joint (90-degree hooks or anchor heads) and their surface texture (sand coated or mechanically deformed). Experimental results showed that all specimens successfully sustained 4.0% loading drifts and that surface texture showed an insignificant influence on the overall behavior.
