BENCHMARK MODEL FOR 3D-FE ANALYSIS OF HIGH STRENGTH BOLTED SPLIT-TEE JOINT

Abstract

Recently, there has been an increase in the number of studies on high-strength bolt tension joints using FE analysis, and it is important to create guidance on how to create an analytical model that can guarantee uniform analytical results. In this study, the effects of element conditions, contact conditions, and modeling of welds and bolts on the analysis results were investigated by FE analysis to propose a benchmark model for three-dimensional FE analysis that can simulate the mechanical behavior of split tee joints in yield and ultimate state. By comparing the experimental results with the analytical results, the analytical parameters that can simulate the experimental behaviors are identified.
