Design of Wavelet Adjusting Method in Preliminary Seismic Analysis

Aimed at the shortage of requiring a large amount of memory and time in structure dynamic calculation, a method of optimizing seismic analysis was proposed, which based on reducing data points and increasing sample interval. The paper takes a three-story frame structure for example, applying Mode Analysis Method for testing and verifying the effects. The results demonstrate that method of wavelet adjustment for seismic wave is effective and reliable. Under the high accuracy condition, it can achieve the purpose of reducing dynamic computation and cutting down calculative time, consequently improve calculative efficiency. Combining each facet of conditions, flow chart of using wavelet to design seismic wave for optimizing preliminary seismic analysis was given out.
