An algorithm for pulse response of non-slip rigid body is developed using ellipse functions. Then seismic response without numerical integration is computable replacing seismic record as pulse series. The numerical experiment shows good accuracy and strange tendency of overturning becomes clear. To investigate and overcome the complexity, overturning response spectrums are proposed with examples using Koube earthquake record. Then the record is approximated by 4 triangular pulse. The attempt showed good coincidence in overturning tendency and explain some reasons of the complexity.
