My copy is a hard copy. I noticed you want a downloadable one. I believe I saw some on the web for sale, just do a search for FM5-34. Thanks for the response
My 1965 version of FM 5-34 has Table 49, Properties of Steel Beams. One column shows a "Max Span Length" followed by the column "Max Bracing Space". What exactly does this Max Bracing Space" refer to?
