The synthesis method of seismic vibrations corresponding to a given family of response spectra

Acceleration time history in the seismic design is required for nonlinear analytical models, for structures that have different at their parts and for structures with a local damping such as piping protected by viscous dampers. A generation algorithm to get required acceleration time history is proposed. The algorithm is based on spectral analysis and multiparametric optimization. Software program that implements the algorithm is verified through numerical examples. Artificial time histories match multiple damping floor response spectra and meet other requirements of the regulatory design guides. Bibliogr. 13. Il. 7. Table 1.
