Drift displacement data based estimation of cumulative plastic deformation ratios for buildings

다국어 초록 (Multilingual Abstract)

The authors’ research group has developed a noncontact type of sensors which directly measurethe inter-story drift displacements of a building during a seismic event. Soon after that event, suchseismically-induced drift displacement data would provide structural engineers with useful information tojudge how the stories have been damaged. This paper presents a scheme of estimating the story cumulativeplastic deformation ratios based on such measured drift displacement information toward the building safetymonitoring. The presented scheme requires the data of story drift displacements and the ground motionacceleration. The involved calculations are rather simple without any detailed information on structuralelements required: the story hysteresis loops are first estimated and then the cumulative plastic deformationratio of each story is evaluated from the estimated hysteresis. The effectiveness of the scheme isdemonstrated by utilizing the data of full-scale building model experiment performed at E-defense andconducting numerical simulations.
