英文摘要	In this paper, an experimental study was carried out on the bolted angle connection under uniaxial tension. The design parameters of the tested connections include angle thickness, bolt hole distribution, bolt diameter and bolt preload. In total 20 specimens were tested with five different kinds of failure modes observed. The experimental results showed that angle thickness, horizontal bolt pitch and vertical bolt pitch all affect the failure modes of the connections and are positively correlated with their ultimate bearing capacity. Significant plastic deformation appeared in both the horizontal and vertical legs of the angle. Based on the experimental results and the corresponding theoretical analysis, a mechanical model of bolted angle connection is proposed to predict its initial stiffness, ultimate bearing capacity and ultimate deformation and verified against the tested results and other mechanical models, in terms of uniaxial tensile load-displacement curves. The proposed model fits with the tested results better than other models. © 2021 Elsevier Ltd
