Overview

Analysis of ground motions using stationary wavelet transform shows 40% lower mean square error, supporting performance-based design in seismic analysis.

Key Points

  • Near-fault ground motions show significant velocity pulses and rupture directivity patterns, impacting structural safety.
  • Results indicate a 40% reduction in mean square error, significantly improving the accuracy of earthquake simulations.
  • Analysis based on over 900 records using methods like stationary wavelet transform enhances seismic input reliability.
  • This work supports performance-based design strategies for long-period structures exposed to seismic risks.
