An experimental study of the response of reinforced masonry building systems to earthquake motions
… 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 …
