Estimate of Rotational Components of Seismic Ground Motion

Resumo

A method for the simultaneous calculation of three rotational components using available translational motion accelerograms is examined, allowing a universal analytical relationship to be obtained between Fourier coefficients for rotational and translational motion. The method has been implemented in Eurosoft Odyssey software (published by JSC Eurosoft) and verified by carrying out seismic calculations at the Kurchenko Central Scientific-Research Institute of Structural Engineering.
