Abstract
Ambient and earthquake response records obtained in several southern California high-rise buildings are analyzed. Building translational and torsional natural periods are estimated and compared. Ambient response is found to be an important indicator of earthquake response. Torsional building response resulting from ambient and earthquake excitation was found to be significant. A design spectrum is developed representing a standardized torsional ground motion of El Centro 1940 Earthquake Intensity.Keywords
