Passive damping technology for buildings in Japan

Abstract

This paper first reviews the concept of the damage‐controlled structure (DCS) which is a kind of passive damping technology, proposed before the Hyogoken‐Nanbu Earthquake in Japan and the Northridge Earthquake in the USA. The philosophy, the necessity and the potential of the damage‐controlled structure are stated in the first two sections of this paper. Second, a modified shear‐bending beam model and a rational dynamic analysis method of three‐dimensional frame for the damage‐controlled structure with passive energy dissipation devices are reviewed. Thirdly, a series of dynamic loading test results of modeled damage‐controlled steel frame with hysteretic dampers are presented. Finally, a number of actual example building projects which exemplify the current seismic design trend using the passive damping technology in Japan are reviewed.

Evaluation of an Innovative Passive Mitigation Device Through Experimental and Numerical Investigation

“…In another study, Papadopoulos P. in 2012 proposed a ne w metal frictional device, the capacity of a restricted rotation around the horizontal axis perpendicular to the vert ical frame plane, in order to increase the seismic capacity of multi-storey planar reinforced concrete (r/c) frames [4]. Another way to protect braced frames is by using buckling restrained braced frames, as it has the same load deformation behavior in both compression and tension and higher energy absorption capacity with easy adjustability of both stiffness and strength [5,6]. In addition, many researchers have proposed the use of post tensioning tec hnology, in braced frames or in moment resisting frames, for residual drift reduction.…”

Analytical and experimental study on mild steel dampers with non-uniform vertical slits

“…Based on the test results, design guidelines and examples have been developed to mitigate the structural response of frames mounted with mild steel dampers (Tsai et al, 2009;Kurokawa et al, 1998), and some successful applications have been made and reported (Wada et al, 2000;Perry et al, 1993;Yasushi et al, 1998).…”

Seismic Retrofitting of Steel Frames with Buckling Restrained Braces

“…The cyclic behavior option for the existing buildings [9,10]. A comprehensive of steel braces subjected to reversed compressive and study of damage controlled structures was performed by tensile force exhibits poor energy dissipation due to the Wada et al [11]; they have presented its potential to buckling limit. The energy dissipation or damage design new constructions and retrofit existing structures.…”
