  seismic spectrum
Each building model has been subjected to a set of site-specific seismic spectrum compatible ground motion records, and the response has been determined using the proposed method and the general method for MDOF systems.
      
In considering the seismic spectrum, one of the methods to incorporate irregularity of fault motion statistically is to introduce the concept of coherency of fracture.
      
In a classic paper,Aki (1967) investigated the scaling law of seismic spectrum on the basis of a statistical model in which an exponentially decaying function is fitted to the autocorrelation function of the dislocation velocity.
      
We show that an analytical function of dislocation velocity gives the same autocorrelation function and the same seismic spectrum as those ofAki's model.
      
In conclusion, it is important to check the seismic spectrum to ensure that the assumed source model does not deviate too far from the desired one.

Does any relation between microtremors and ground motion induced by the earthquake exist? And what is the relation like? There are different answers by different researches The Songpan earthquake in 1976 suppolied, the chance to discuss this problem. From the investigation of we come to the following conclusions: (1)Both the acceleration and the maximum amplitude of Fourier spectrum of gr, ound surface motion induced dy earth quake increase with the earthquake magnitude increasing; and both the amplitude of microtremors and its Fourier spectra increase with the altitude of observation site and the thickness of alluvial stratum increasing. (2) The amplitude of microtremors and the surface motion induced by different series of earthquake in the same site appears to have certain direction. (3)The characteristics of the Fourier spectra of the same series of earthquake are exactly alike. (4)The old style wooden house of one storey does not affect the spectrum of microtremors, but the site condition obviously affects the Fourier spectrum of the microtremors of the wooden house.

地面脉动与地震地面运动之间有没有关系?是什么关系?众说不一。1976年松潘地震记录提供了探讨这一问题的条件。我们对台址进行了各种工作之后,得出的结论是:(1)地震地面运动加速度和富氏谱峰值随震级而增大;脉动幅值及谱幅值随测点高程及地表沉积层厚度而加大。(2)同一地区脉动和不同序列地震记录的幅值及谱幅值的最大值,均有一定方向性。(3)同一序列地震谱曲线特征极为相似。(4)一层穿斗木架房屋结构对地面脉动频谱特性没有影响;而后者在前者的谱曲线上有明显反应。结论:从1976年松潘地震文县台址的资料分析来看,地面脉动频谱特性在地震地面加速度谱形态或特征方面关系不明显。

In this paper the mode shapes and seismic response of a jack-up drilling rig are analysed. The structure of the jack-up is idealized as an assemblage composed of 3-D beam elements. The legs in the assemblage are considered as beams by means of the equivalent legs. The seismic spectrum curve in Reference [1] is used for calculating the seismic response. First, the lowest 5 eigenfrequencies and modes of the jack-up are solved, then the maximum displacement and stress responses are calculated by the spectrum analysis...

In this paper the mode shapes and seismic response of a jack-up drilling rig are analysed. The structure of the jack-up is idealized as an assemblage composed of 3-D beam elements. The legs in the assemblage are considered as beams by means of the equivalent legs. The seismic spectrum curve in Reference [1] is used for calculating the seismic response. First, the lowest 5 eigenfrequencies and modes of the jack-up are solved, then the maximum displacement and stress responses are calculated by the spectrum analysis method based on mode superposition method, and finally the results for both types of supports, in the water depth of 30m and 50m aregiven and compared.
