Historic Earthquake Damage for Buildings and Damage Estimated by the Rapid Seismic Analysis Procedure: A Comparison

摘要

As part of the Navy's earthquake hazard reduction program, selected structures at various Navy activities were analyzed by the rapid seismic analysis (RSA) procedure to determine their seismic adequacy. Those buildings found to be inadequate were then analyzed in detail to determine the degree of strengthening required to reduce the potential damage and the estimated cost. The RSA-estimated damages for steel, concrete, masonry, wood, and brick buildings were compared with historic earthquake damage data. Results indicate reasonably good agreement between the RSA-estimated damage and historic earthquake damage data. Keywords: Damage function, Earthquake damage, Maximum ground acceleration, and Replacement cost.
