Shake-Table Tests of Large-Scale Shear Wall and Infilled Frame Models.

Three different types of wall construction scale models were tested dynamically to ultimate failure by subjecting each of them to a sequence of simulated earthquakes of progressively increasing magnitudes on a 5 m×5 m shaking table in order to evaluate and compare their seismic performance. The three models tested are: a reinforced concrete shear wall structure; a masonry infilled reinforced concrete frame structure; and a concrete infilled steel frame structure, all having the same dimensions and designed to represent typical wall constructions. From the shake table and small amplitude vibration tests, the seismic behavior, damage characteristics, structural degradations and dynamic shear strengths, etc., of the models are studied and compared.
