- Abstract
- Papers are presented on geological considerations and techniques for microzonation, earthquake damage prediction and construction of microzoning maps, and site response and interaction. Meanings and uses of earthquake intensity are analyzed and requirements related to earthquake intensity in structural design during various stages of progress in earthquake-resistant structures are explained. The use of ground motion parameters in structural design without reference to earthquake intensity is indicated. Methods for improving maps which depict the earthquake ground-shaking hazard are explored. It is suggested that the frequency-dependent effects of the earthquake fault and the geology be incorporated with propagating seismic waves. The dynamic response characteristics of building structures under earthquake and blast excitations are compared, and a method is suggested for producing an equivalent blast shock with various frequency, amplitude, and duration which will produce the same effect on structural response as an earthquake of the same intensity.
