| Abstract: | The author of this paper briefly reviewed the history of evaluation of seismic safety for engineering sites, some important technical issues, the tendencies of development, and renewal of the relevant techniques and methods. The consistency of probability levels for different earthquake effects is discussed in this paper. At the same time, other technical problems related to evaluation of seismic safety are analyzed, which includes the selection of seismic probability level, consideration of uncertainty for seismic hazard analysis, modeling of ground motion attenuation laws, parameter matching of synthetic acceleration time history, earthquake response analysis of soil layers, determination of design ground motions. Some ideas and suggestions are proposed for solving these problems. |
