Abstract
The objective of this study is to evaluate the assumption that there is no amplification of ground motion at the top of unreinforced masonry walls.
Strong-motion records at the top and bottom of shear walls for one unreinforced masonry building, and four reinforced concrete buildings were
analyzed. Accelerations at the top of reinforced concrete shear walls typically did not exceed 1.31 times ground accelerations. The unreinforced
masonry building was damaged during the motions analyzed making results unreliable for predicting future motions.
