SIMULATION OF NONSTATIONARY STRONG GROUND MOTIONS CONSIDERING PHASE PROPERTIES AND FAULT MODELS
|
抄録（英）：
A method to simulate nonstationary strong ground motions is presented. At first, the relationships between the nonstationary nature of an arbitrary random-like function of finite duration and the phases obtained from Fourier analysis of the function are summarized. It is shown that, by changing the nature of the phases, the desired nonstationarity of frequency contents can easily be introduced into the function. Furthermore, based on phase characteristics and utilizing a fault model, seismic wave motions with definite nonstationarity are synthesized.
