The issues of present seismic wavelet frequency caused by different concepts, such as apparent frequency, dominant frequency, peak frequency and centroid frequency, etc., which are defined by different methods, and understanding deviation, definition of seismic wavelet frequency for time and frequency domain are concluded and summarized. On this basis, three kinds of seismic wavelets in common use such as Ricker and Zinc wavelets as well as sine wavelet with exponential attenuation characteristics are analyzed and a conclude is achieved that apparent frequency and dominant frequency are consistent in essence, but peak frequency and centroid frequency as well as apparent frequency or dominant frequency are not completely consistent with different seismic wavelets. For actual seismic data, peak frequency can approximately be used as dominant frequency, but it is not suitable when seismic wavelet is known for it can give out any wrong knowledge and results.

Since the installation of fire safety is not a part of a building structure and the seismic building design code does not include fire water pipings, the design of them in Taiwan does usually not consider the seismic effect. This study first collected and summarized the relevant seismic design codes and fire control standards from U.S., Japan, China and Taiwan to understand the internationally adopted methods for seismic from designs of fire water pipings. This study also gathered engineering cases and photographs of the installation of the shock resistance hangers of fire water pipings in high technology factory buildings. Then, this study presented a proposal for seismic design principles. we hope this can attract attentions from government authorities and the fire safety business sector and to rise concerns of the seismic design of fire safety installation; and therefore set up a clear and practical criterion for the engineers and finally reduce the damage of post earthquake fires.
