Abstract
This paper explains about numerical analysis of RC column accompanied with friction damping mechanism (FDM) under cyclic loading based on the previous experiment. This is new structure system contains three parts of concrete column connected with friction devices together PC bolts confinement. The experiment was performed with cyclic loading test in some variations of PC bolts confinement distribution scenario. In this study non-linear finite element analysis is performed by modeling the column with fiber section element and the friction devices with two-node-link-element. The important parameter in this study is constitutive material of friction devices, concrete, and steel. The hysteresis curves comparison between experiment and numerical results show that the peak forces in the every last loops and hysteresis curves shape characteristics have similarity as well as on the main stiffness and the distributions of moment curvature patterns. The force and displacement monitoring are useful to know the confinement distribution role the slip distribution to each friction devices.
