Seismic behavior of tall building structures by friction damper

Large-magnitude long-distance earthquakes generated from Sumatra have significant potential engineering implications in Singapore and Malaysia Peninsula due to accentuation by resonance in buildings. Historical seismicity data of the region covering the past 100 years shows numerous occasions when l...
