RESPONSE CONTROL EFFECT OF HI-RISED REINFORCED CONCRETE BUILDING USING COUPLED VIBRATION CONTROL STRUCTURE

Katsuhisa Nishimura, Yoshiyuki Fukumoto, Yusuke Wada

Abstract

Authors designed the system connecting multi-story shear wall structure with short period and main structure constructed by rigid frame with long period located around it with hydraulic dampers, and applied this system to 45-story reinforced concrete building.By response analysis, we confirmed as follows, reducing response deformation of main structure by connecting these structures with viscous dampers, height distribution of maximum story shear of multi-story shear wall structure was shape like stairs increasing at stories laying dampers, energy absorbed by dampers occupied about 70% for input energy of earthquake.
