A bonded sleeve connection was developed for joining tubular glass fiber-reinforced polymer (GFRP) beams and columns. It utilizes a sleeve connector made by welding a steel tube to a steel endplate. The steel tube is then inserted into and adhesively bonded with the GFRP beam end and the endplate is connected to the GFRP column using through-bolts. Four beam-to-column specimens with different bond lengths between the GFRP beam and steel tube and different numbers of bolts were tested. The moment-rotation responses, failure modes, and local strain responses were experimentally received and comp...
