Abstract

Abstract: Based on ABAQUS finite element simulation software, this paper studies the seismic performance of GFRP beam-column new end-plate joints under low-cycle repeated loading with two different connection methods: bolted connection and adhesive-bolt hybrid connection. To investigate the effects of different bolt preloads and adhesive joint lengths on the seismic performance of the joints, eight specimens were designed for finite element analysis in terms of hysteresis curve, skeleton curve, energy dissipation capacity, and stiffness degradation. The results showed that the hysteresis curve of the new end plate joints is fuller and the enclosed area is larger. With the increase of bolt preload, the load carrying capacity, stiffness and energy dissipation of the joints were improved; the stiffness of the adhesive-bolt hybrid joints also improved more than that of the bolt only joints.

Key words: adhesive-bolt hybrid connection, GFRP beam-column joints, new end-plate joints, seismic performance, finite element analysis
