To predict the accurate behavior of bolted joints, detailed 3-D modeling is needed that considers the contact friction, preload, and nonlinear behavior of joints. However, a detailed model with gap elements cannot ensure convergence due to the complicated shape, plus it is inappropriate for a dynamic analysis. Accordingly, this paper suggests three kinds of model for structures with bolted joints: (1) detailed model, (2) practical model, and (3) simple model, which can be selected based on the purpose of the analysis. Through a static experiment using a strain gauge, the accuracy of the detailed model was verified, and the results of a modal test compared with the results of the simple model to confirm its effectiveness in a dynamic analysis. In the case of a static analysis using the simple model, the analysis results almost corresponded with those of the detailed model for a part 2.5d away from the center of the bolt. Among the proposed models, the simple model has the least degree of freedom and requires 59% less memory than the detailed model.
