Numerical Investigation on Structural Behaviour and Curling Influence of Aluminum Alloy Bolted Connections

초록

Numerical simulation is utilized to estimate the structural behaviors such as ultimate strength, fracture mode and curling effect of single shear bolted connections fabricated with aluminum alloys. In the Kim’s previous research, the validity of finite element analysis was verified through the comparison of test results and analysis results. In this paper, curling deformation and strain development between test result and analysis result were investigated. Also, additional parametric studies are performed for bolted connections with other variables of edge distance and end distance, which are not considered in the existing experiment. The conditions of end distance and edge distance for curing occurrence were discussed.
