Displacement Based Seismic Design

In this paper, a displacement-based seismic design procedure is presented for reinforced masonry shear-wall structures, with the objective of being more consistent, transparent, and practical than current force-based seismic design procedures. The procedure anticipates the formation of a plastic mechanism at specified target displacements, calculates the local deformation demands associated with that mechanism, and ensures that those local deformation demands remain below deformation capacities for flexure-dominated and shear-dominated wall segments. Guidelines to determine the target displacements and effective damping properties for reinforced masonry wall structures are provided. The proposed procedure and guidelines are used in a trial application to design a full-scale, two-story reinforced masonry shear-wall system.

Displacement Based Seismic Design

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.
