The purposes of this investigation were to (a) extend previously developed elastic spring models for bolt assemblies to include simulating creep loss in the bolt and the threads and (b) to present an approach in which appropriate spring stiffness in the model are determined rationally. Previous efforts at modeling tension in bolts have been limited in that they were not readily applicable to analyses of realistic bolted connections. The simulated load distributions on the shank and the threads in a single-bolt assembly showed good comparison to the gathered experimental data as did the simulated, time dependent creep loss in the bolt. The ultimate goal of this research is to develop a model that includes nonlinear behavior that is suitable for investigating realistic multi-bolt connections.
