Seismic drift demand and capacity of non-seismically designed concrete buildings in Hong Kong

Abstract

This paper reviews the seismic engineering research conducted in Hong Kong with special emphasis on the prediction of the seismic drift demand and capacity of existing buildings which have not been designed and detailed to address potential seismic hazards. The paper begins with a comprehensive summary of the local construction and detailing practice of concrete structures, followed by a summary of the drift ratio capacity, ductility capacity, stiffness variation and non-linear damping properties of the non-seismically designed reinforced concrete components. Seismic design response spectra for rock sites developed from Chinese Code GB50011-2001 are compared with the uniform hazard response ..
