Drift displacement data based estimation of cumulative plastic deformation ratios for buildings
Nishitani, Akira,Matsui, Chisa,Hara, Yushiro,Xiang, Ping,Nitta, Yoshihiro,Hatada, Tomohiko,Katamura, Ryota,Matsuya, Iwao,Tanii, Takashi Techno-Press 2015 Smart Structures and Systems, An International Jou Vol.15 No.3
The authors' research group has developed a noncontact type of sensors which directly measure the inter-story drift displacements of a building during a seismic event. Soon after that event, such seismically-induced drift displacement data would provide structural engineers with useful information to judge how the stories have been damaged. This paper presents a scheme of estimating the story cumulative plastic deformation ratios based on such measured drift displacement information toward the building safety monitoring. The presented scheme requires the data of story drift displacements and the ground motion acceleration. The involved calculations are rather simple without any detailed information on structural elements required: the story hysteresis loops are first estimated and then the cumulative plastic deformation ratio of each story is evaluated from the estimated hysteresis. The effectiveness of the scheme is demonstrated by utilizing the data of full-scale building model experiment performed at E-defense and conducting numerical simulations.
