Abstract:

Most existing structures were not designed to today's seismic codes and standards, and in fact in low seismicity regions codes did not require seismic design until recently. Further, older structures were usually constructed with different configurations and structural systems than commonly used for modern seismic resistant structures. The less seismically active regions still employ structural systems and construction methods that are no longer used in the more active regions, and it is difficult to translate the rules and general understanding of seismic performance to these systems. These observations are particularly true in the Eastern and Midwestern regions of the United States, where seismic design criteria have only recently been established.
