The ATC-33b (FEMA 274) report, NEHRP Commentary on the Guidelines for the Seismic Rehabilitation of Buildings, was developed under a contract with the Building Seismic Safety Council, for the Federal Emergency Management Agency (FEMA) under the ATC-33 project (Published 1997, 492 pages). It was initially published as a companion document to the FEMA 273 Guidelines for the Seismic Rehabilitation of Buildings. While FEMA has discontinued the distribution of the FEMA 273 report, the FEMA 274 Commentary is still pertinent to the FEMA 356 Prestandard and Commentary for the Seismic Rehabilitation of Buildings, which was prepared by the American Society of Civil Engineers.
