Expansion Joints for Exposed Structural Steel
Expansion Joints for Exposed Structural Steel
(OP)
Does anyone know of a technical document and/or spec. that outlines & discusses expansion joints for exposed structural steel?
I've already read thread594-20505 from this site, however, this thread discusses BUILDING expansion joints and makes no reference to long, non-building steel structures in direct exposure to the sun and the temprature changes.
For example,
I am designing a structural steel pipe trestle that will be on the roof of an automotive plant. The trestle has overall dimensions as high as 900ft. Expansion joints will be needed and I am seeking supportive technical/spec documentation simular to the one mentioned in thread594-20505 but in regards to exp. joints for whether exposed steel.
Any help would be most appreciated.

For shelf angles, I don't like to go beyond 20' or 30' realizing that temperatures can span from -40C to +30C.
Was involved with a project near Bancroft, Ont where they had 900' without control joints. My memo recommended against the manner of support... no control joints and a diagonal brace to grade at the one end. Last I heard, they were talking to lawyers.

If you are really worried, you may be able to measure temperature effects with your analysis package (including additional stresses in supporting members)
