| Outline of Final Research Achievements |
A seismic retrofit design procedure for existing steel frames using stud-type dampers was proposed in consideration of the interaction between the damper and surrounding frame. As a stud-type damper, slitted steel shear wall stiffened by plywood panels which is characterized by its light weight and compact size was used in this study. The validity of the design procedure was confirmed by cyclic loading test of a 1-story 1-span steel frame with a stud-type steel shear wall. In addition, a series of analyses of two multi-story frames using a hysteretic model of the steel shear wall that was made based on dynamic loading tests was conducted to verify the efficacy of the generalized design procedure. Also the efficient deployment and response reduction effect of the stud-type steel shear wall was confirmed for various kinds of earthquakes.
