• Development of Steel Construction. These pages provide a brief history of the evolution of the use of steel as a material for buildings in seismic regions. (Currently being written). 
• Steel Buildings in Past Earthquakes.The 1994 Northridge and 1995 Kobe Earthquakes provide the most recent information, but numerous steel structures have been subjected to past earthquakes. 
• Factors Influencing the Behavior of Steel Structures
• SAC Phase 1 Studies 
• Reference Library 

SAC Phase 1 Studies - The Phase I Studies were combined into volumes and published as Technical Reports, which are now available from ATC by referencing the report numbers.  Below are the Technical Reports with the included Phase I Studies.  The summaries for each Study are available by following the links.
