Dynamic Response of Coupled Wall Systems
Publication: Journal of the Structural Division
Volume 108, Issue 8
Abstract
Results of an experimental investigation to determine the inelastic dynamic behavior of reinforced concrete coupled wall systems under severe earthquake motions are reported. These tests show that the natural frequencies of reinforced concrete structures are reduced to as much as 50% of the initial uncracked values during the first few seconds of a strong earthquake, additional reductions in the natural frequencies are not as significant as those caused by the first shock even if the aftershocks are significantly stronger than the first one, the size, strength, and ductility of the coupling beams are the controlling factors in the mode of failure of coupled wall systems, and although the test structures were subjected to severe inelastic behavior, some characteristics, such as modal shapes, nodal points, and amplification (filtering) along the height of the structure were similar to those of linear elastic systems.
