Steel Joist Properties (SJ#) in year 1933

[Subject Prev][Subject Next][Thread Prev][Thread Next]
A existing building constructed in 1933. 

The roof and floors are 3" thick concrete over  steel
joists @ 2'-0" o/c. On plan, only SJ#81, SJ#82,
SJ#103, SJ#123 & SJ#125 were called out without any
joists' properties.

Can any one tell/fax me what are those joists and
their properties, allowable loads verse span, etc.

Thanks in advance.
