EXPERIMENTAL STUDY OF PASSIVELY-CONTROLLED HANGED CABLE RACK FOR ELECTRIC WIRING

Abstract

Hanging type cable rack system partially had serious damage during the Tohoku-oki Earthquake, March 11, 2011. The objective of this paper is to understand the seismic performance of the cable rack system and to propose passive control scheme for the system. Monotonic loading tests of the cable rack and shake table tests of hanged cable rack are conducted. Performance of the specimens is discussed by referring to maximum deformations, displacements, absolute accelerations, relationships of damper force and damper deformation.
