Abstract

This paper presents the results of earthquake simulation tests on a 1:15 scale 25-story RC flat-plate core-wall building model satisfying the detailing requirement of the special shear wall system. The following conclusions are drawn based on the test results: (1) The fundamental period of the test model simulates well that of the prototype obtained using the elastic mode analysis at the design phase, and the base shear coefficient of the test model shows much larger values than that estimated in accordance with KBC2009, or IBC2006. (2) In the test, the vertical distribution of acceleration under the shake table excitations reveals the effect of the higher modes with the free vibration after the termination of shake table excitations being governed by the first mode. (3) The maximum inter-story drift ratio of the test model, 0.43%, under the design earthquake in Korea was much smaller than the design limit, 1.5%. And, (4) the modes of cracks appear to be the combination of flexure and shear in the slab around the peripheral columns and in the coupling beam.
