Global Topics Report on the Prestandard and Commentary for the Seismic Rehabilitation of Buildings.
Federal Emergency Management Agency, Washington, DC., November 2000, 468 p.
Among the FEMA documents covering the topic of making existing buildings more resistant to the effects of earthquakes, this volume occupies a unique position: it is the only one that fulfills a historical need. When the decision was made to convert the performance-based Guidelines for the Seismic Rehabilitation of Buildings, FEMA 273, into a prestandard containing mandatory language (FEMA 356), there was considerable concern among design professionals that some of the major characteristics and salient features of the original document (or indeed its very fabric) would be adversely affected in the conversion process. This volume was purposely conceived to allay such concern by providing a transparent and permanent record of the changes that were made and the reasons for such changes, as well as the major challenges encountered in the conversion process and how they were resolved. It is hoped that this volume will also serve as a useful tool in facilitating the further conversion of the prestandard into an ANSI-approved standard by the American Society of Civil Engineers.
