Lintel Lateral Bracing
Lintel Lateral Bracing
(OP)
The question of lintel lateral bracing has come up. Some engineers are designing steel lintels assuming the block provides lateral bracing for the lintel (either top flange lateral bracing or torsional bracing) and some engineers assume fully unbraced along the span. We even have some guys who are taking the unbraced length as half of the lintel span.
I am looking for a formal paper or write-up or documentation that disucsses this topic as I need to come up with presentation material to back up an engineering opinion. Can anyone please help.

Brick veneer is tied back to the metal wall, but it also has varying stiffnesses depending on the span of the opening and the way in which the stud wall (whether metal or wood) is framed.
RE: Lintel Lateral Bracing
If you're coming up with a huge wide flange beam for a large lintel span, you may try using a tube, as unbraced length won't have much of an effect.

Here is another document - althought not specifically about structural steel lintels it has some similar concerns. In particular see Paragraph 8-6

RE: Lintel Lateral Bracing
The brick depends on the lintel to hold it up and the lintel then depends on the brick to keep it from failing?? Sounds like the analogy of two drunks leaning against each other....who is holding up whom?
RE: Lintel Lateral Bracing
The document mentioned in "SlideRuleEra"'s first post outlines an "opinion" as to the lateral bracing requirments. There is no supporting calculations or research information. I am still at square one with this topic. Some engineers design steel linteals at UNBRACED, some engineers design as fully brace, and others use their own magic/theory to determine unbraced length
Since Steel linteals are not a new invention I would suspect that someone out there has some form of technical document or research paper that discusses the lateral bracing capablity on the linteal from the block while ignoring how close the linteal is to the roof or floor framing.
Any help would be well appreciated.
