METHOD OF SELECTING DESIGN EARTHQUAKE GROUND MOTIONS FOR TALL BUILDINGS

摘要

In most current seismic design procedures, and earthquake hazard of the design earthquake load is usually defined as a 10/100 probability of exceedance in 50 years. However, tall buildings and emergency hazard facilities need to be safe against more sever ground shakings than code-defined design earthquake hazards. Earthquake hazards. Earthquake hazard can be expressed by a 5/100 damped Linear Elastic Design Response Spectrum (LEDRS) obtained from statistical research using spectral responses of selected EarthQuake Ground Motion (EQGM).
