| The Discussion on Principles of Seismic Zonation of the Next Generation |
| Abstract： Based on the review of seismic zonation in China and the situations of the development of society and economy in China in the future decades as well as the earthquake safety policy of the government, the principles of seismic zonation of the next generation are discussed in this paper. The earthquake ground motion parameters will be used to the seismic zonation as the last once. The first principle is the consideration of anti-collapse of the buildings. We proposed the Maximum Considered Earthquake (MCE) with exceeding probability 2% within 50 years as the basic design level for anti-collapse of the building. The parameter with the value of 1/5—1/6 MCE will be used as the elastic deformation design. The key techniques for compiling the new seismic zonation map of China are also discussed in this paper. |
