Abstract
When considering social function of railway viaduct as infrastructure, less damage control is demanded even against significant earthquake. Response control technique with damping device is highly expected as alternative solution. In responding, authors have developed Arc Shaped Dampers. In order to investigate applicability of the proposed damper to moment frame type rail way viaduct structures, seismic retrofit design, nonlinear analysis and experimental loading tests have been conducted to verify present technique. Following results were obtained: the existing structure is failed in post yielding shear, while retrofitted structure assures flexural yielding ductile behavior with higher damping effect.
