Investigation of Current Seismic Design Provisions for Reinforced Masonry Shear Walls
Current seismic design provisions were investigated to determine if optimum designs resulted from their use. Forty-two components of recorded ground motions were used for the investigation. These ground motions were recorded in the Imperial Valley in 1940 and 1979. These ground motions were assumed to contain a consistent value of soils factor. The tabulation of the Imperial Valley ground motion revealed that these motions had mean velocity-acceleration ratios and velocity and acceleration amplification factors that exceeded those determined by prior studies. The investigation confirmed that a modified seismic design formula provided a more consistent dynamic behavior for reinforced masonry shear walls. The investigation also studied the influence of reinforcement ratios of masonry shear walls, the influence of under and excess strength, and the effectiveness of stiffness modification in lieu of strength modification.
