Shake-Table Tests of a Full-Scale Three-Story Reinforced Masonry Shear Wall Structure

This paper provides a comprehensive validation of a displacement-based seismic design procedure proposed in a companion paper for reinforced masonry shear-wall structures. For this purpose, a full-scale, two-story reinforced masonry specimen was tested on a shake table to examine the global and local behaviors of a low-rise reinforced masonry building designed by the proposed displacement-based procedure, and to validate the analytical tool used in the design process. This specimen successfully resisted repeated ground motions with intensities up to the maximum considered earthquake (MCE). Its performance on the shake-table demonstrates that a reinforced masonry structure designed, detailed, and constructed according to the proposed displacement-based design procedure can resist MCE earthquakes without collapse even though it may suffer severe damage. In critical regions of this specimen, elements detailed in accordance with displacement-based requirements showed more inelastic deformation capacity than the deformation limits imposed by the displacement-based design provisions proposed here. The proposed procedure produces structures that behave according to design expectations, even though severely damaged.

Masonry Shear Wall

Many frame-supported masonry shear-wall structures were observed severely damage in Wenchuan Earthquake. In this paper, an inter-story isolation system is implemented in such structures to mitigate the hazard of the earthquake. The mechanism of the mixed system is demonstrated by theoretical and numerical analysis. And it is concluded that the mass ratio, the below-stiffness ratio, the yield shear of isolated layer and the up-stiffness ratio are the main parameters whose effects are discussed separately. For the design convenience, a set of fitting equations of these parameters are provided.
