摘要：

The rotational component of seismic strong-motion is attracting attention since it is becoming evident that it may contribute considerably to the overall response of structures to earthquake motions. This paper presents an improved method for calculating the time histories of torsional and rocking components of ground motion corresponding to a set of three recorded orthogonal translational components. The mathematical model is based on a detailed representation of soil impedance and contributions of body waves. The dependence of the angle of wave incidence on the frequency of wave is properly given in the calculation of rotational components with consideration of critical incident angles. Numerical results of the torsion and rocking obtained from a set of three recorded translational components are also presented. (C) 2004 Elsevier B.V. All rights reserved.
