Scaling of design earthquake ground motions for tall buildings based on drift and input energy demands

摘要: Rational scaling of design earthquake ground motions for tall buildings is essential safer, risk-based buildings. This paper provides the structural designers with an insight more rational based on drift and input energy demands. Since a resonant sinusoidal motion can be approximate critical excitation to elastic inelastic structures under constraint acceleration or velocity power, variable period duration used as wave near-field far-field motions. enables one understand clearly relation intensity normalization index (maximum acceleration, maximum velocity, power) response performance (peak interstory drift, total energy). It proved that, when adopted index, exhibits stable property irrespective number stories. further shown power finally concluded that former peak hold practical spectrum-compatible
