In this study, dynamic characteristics of both traditional and new Korean-style houses according to excitation amplitude were evaluated through shaking table tests of 1/15 scale models. Along with the experiments, nonlinear structural analysis which considers frictional characteristics of joints was also performed and both the experiments and analysis results were compared. As the excitation amplitude increased, natural frequency of the experimental models and maximum magnitude of transfer functions decreased. This indicates that stiffness of the structures is much related with the excitation amplitude. As the excitation amplitude increases, damping ratio of the traditional Korean-style house has increased much more than that of the new Korean-style house. This explains that energy dissipation capacity of the traditional wooden joints is bigger than that of the modern steel joints. The analysis results which considers nonlinear frictional behavior of joints showed that bi-linear model can be used for modeling the joints of new Korean-style house, but another frictional force should be considered for simulating the experiments of the traditional Korean-style houses. |
