Abstract |
Recently, there are highly interests on structural damping to improve resistance of seismic and wind. It has been frequently used hysteresis damping devices made of steel because of economic efficiency, construction, and maintenance. This paper presents the effective reduction of seismic response by using Kagome damping system(SKDS) in rahmen system apartment building. The proposed system is designed to be activated by the relative displacement between the building and the stairs. It is performed nonlinear dynamic analysis to review the effects of earthquake response reduction for the 20-stories rahmen framed apartment building. In the analysis of the SKDS system, the reduction of maximum response displacement, maximum response acceleration and layer shear force are compared with the seismic design, and the result show that allowable story displacement is satisfied with Korean Building Code (KBC 2016).
