PLASTICITY JUDGEMENT OF HYSTERETIC DAMPERS OF A HIGH-RISE PASSIVELY CONTROLLED BUILDING UNDER WIND RESPONSE USING THE RECOMMENDATIONS FOR LOADS ON BUILDINGS
The current wind-resistant design of structures is performed under the assumption that the main structure is kept to an elastic state and mainly relies on design guidelines for load recommendations on buildings. However, as the building’s height increases, it becomes subjected to stronger external wind forces. In this circumstance, if a hysteretic damper is installed in a high-rise building, there is a possibility that the damper may behave plastically due to larger external wind forces. Therefore, understanding the plasticity behavior of hysteretic dampers installed in high-rise buildings under the load recommendations on buildings will pave the way to easily evaluate the elasto-plastic behavior of these passively controlled buildings. As such, this paper shows the judgement of the hysteretic damper plasticity against external wind force based on the elastic shear force of passively controlled high-rise building calculated using the recommendation for loads on buildings, and investigates the accuracy and problems in plasticity judgement.
