STRENGTH EVALUATION OF SINGLE-SHEAR BOLTED JOINTS WITH ADHESIVE BONDING

Abstract

Adhesive bonding has been increasingly used for seismic retrofit and repair recently. However, the interaction between bolt and bonding joints is not clear in detail. This study focuses on the hybrid joint method using adhesive bonding and high-strength bolts for the single-shear lapped joint to improve joint strength. Three experimental parameters, with or without adhesive, bonding area, and bolt tension, were adopted. The results show that the connection strength can be effectively increased by adhesive. Moreover, the effective adhesive area and strength evaluation formulas are proposed through the cohesion failure behavior.
