Concrete Coupled Walls: Earthquake Tests
Publication: Journal of the Structural Division
Volume 107, Issue 5
Abstract
Tests of six approximately one-twelfth scale reinforced concrete coupled walls under seismic loading are described; the results are compared to collapse mechanisms calculated by conventional means. Five structures were subjected, on an earthquake simulator, to the base acceleration record measured at El Centro, California, during the Imperial Valley earthquake of 1940; one was subjected to slow cyclic loading into the inelastic range. The major variables in the study were the strength and stiffness of the connecting beams. In evaluating the experimental results, the effect of microcracking on the initial stiffness of the structure is noted, as are the effects of higher mode response in the accelerations, base shear and base moment. Using lateral loading in the shape of the first mode, the collapse mechanisms for the test structures, varying with strength and stiffness of the connecting beams, were determined.
