Title:Experiments to Study Earthquake Response of R/C Structures with Stiffness Interruptions
Author(s):Moehle, J.P.; Sozen, M.A.
Subject(s):earthquake motions
Abstract:An experimental study was undertaken to investigate the response to strong earthquakes of R/C structures having abrupt interruptions in adjacent story stiffness. Four structures (total weight of 2.29 meters) comprising two nine-story, three-bay frames or two frames and a wall which acted in parallel were tested. The first story was twice the height of other stories. The experimental variable was the wall hei0ht with structures having either no wall or walls which were one-, four-, or nine-stories tall. Experimental measurements include displacements, accelerations, and forces between frames and walls at each level. Observed behavior is interpreted using simple, design-oriented numerical models. Studies using linear models include (1) comparison of modal-spectral and equivalent static procedures and (2) estimates of response maxima using SOOF oscillators. Studies using nonlinear models include (1) interpretation of behavior for a monotonic lateral loading distribution and (2) estimates of displacement maxima and waveform using SOOF models.
