Abstract:Traditional coherence functions ignore the time-varying characteristics of ground motions, influencing the accuracy of simulating multipoint nonstationary ground motions. An effective process is proposed for building the time–frequency lagged coherence expression to describe the spatial variation in both the time and frequency domains. First, the advantage of wavelet packet transform (WPT) in recognizing the time–frequency characteristics of signals is leveraged. The WPT is used to analyze the time–frequency c… Show more
