"The primary purpose of this document is to provide a selected compilation of seismic rehabilitation techniques that are practical and effective. The descriptions of techniques include detailing and constructability tips that might not be otherwise available to engineering offices or individual structural engineers who have limited experience in seismic rehabilitation of existing buildings. A secondary purpose is to provide guidance on which techniques are commonly used to mitigate specific seismic deficiencies in various model building types. This document supersedes FEMA 172, NEHRP [National Earthquake Hazards Reduction Program] Handbook of Techniques for the Seismic Rehabilitation of Existing Buildings, which was published in 1992."
