Abstract
To ensure the consistency of building collapse risk within the country, a risk-targeted seismic zoning map is proposed. The risk integral method calculates the target risk by the convolution of the seismic hazard curve and the structural vulnerability curve. Currently, the use of risk-targeted seismic zoning maps has been widely used in practice in the United States, and related studies have been conducted in France, Romania, Canada, Indonesia, Europe and China. This article introduces the basic principles of using the risk integral method to determine the risk-targeted ground motion parameters and reviews the recent progress of research and application of this technique in China and abroad. In addition, we discuss the future development of risk-targeted seismic zoning maps and some of the problems may face.
