- Abstract
- Experiments were performed to study the dynamic response of reinforced concrete masonry building structures. Two reduced-scale reinforced masonry perforated shear wall structures were subjected to simulated earthquake motions on a shaking table. A third was tested using conventional static methods to provide insight into differences in behavior of systems that are subjected to artificial static forces and those allowed to develop natural inertial forces. Experimental data were studied to determine trends in nonlinear dynamic response and to evaluate current practice for seismic design and analysis. Common linear models for assessing lateral drift and distribution of story shear among vertical elements were found to be inadequate for response in the nonlinear range. Analysis of measured response identified simplified procedures for evaluating lateral strength and seismic drift of reinforced masonry structures.
