Abstract
Sawada et al. proposed a combined RC column with friction damping mechanism and have been examining its practical application through cyclic loading tests. We conducted numerical simulations of the experiment based on three-dimensional elastic-plastic analysis in order to examine the analytical model. To gain good agreement between the experiments and simulations, we needed to append binding forces to that model, because the column was already in damaged condition before loading. We got a better agreement between them by applying a sequence loading to the columns in the simulations, for the specimen had been subjected to a series of cyclic loading in the experiments. However, it is necessary to further improve the analytical model and condition, because in large strain levels in a few cases, the maximum bearing force, hysteresis damping and strain hardening properties of the seismic structure system are different between the experiments and analyses.
