Abstract
An analytical model, calibrated with the results of shake-table tests on a 1:15 scale 25-storey RC flat-plate core-wall building model, is used to predict the demand of ductility at the critical elements. Under the maximum considered earthquakes in Korea, the maximum chord rotation of coupling beams and slabs reaches 0.01 rad with the maximum roof drift being 0.5%. The maximum curvature of the wall at the base is only 16% of the ultimate curvature, 0.041 rad/m, corresponding to the minimum plastic rotation 0.0064 rad, implemented by ACI 318 for the special-wall boundary. These results indicate that the seismic requirements for ductility in ACI 318 can be greatly alleviated for high-rise buildings in a moderate-seismicity region such as South Korea.
