Seismically Resistant Design – Past, Present, Future

摘要

Seismic exposure has extended over many centuries, but serious, thoughtful seismic design has occurred over the past 100 years in California, since the 1906 San Francisco Earthquake. In the past 70 years substantial change and progress have taken place, not only in California, but over the entire United States, so that we can now utilize concepts and systems that previously we could only dream about. This paper will outline the past, present, and projected future of seismic design.
