Re: single angle members

[Subject Prev][Subject Next][Thread Prev][Thread Next]
We use single angles as webs in trusses all the time.  Reference AICS 9th addition pp. 3-53 thru 3-58 and pp. 5-309 thru 5-323 for specifications and examples.

Hope this helps.

I would assume an eccentric loading if the resutant does not pass through
the appropriate point.

I prefer channels.

Watch out for points where moisture can not get away if it is outside.  Once
had to demolish a 120 foot truss 180 feet in air that had solid rust bottom
chords.

the angles are welded to the gusset plates, is there still a concern on
eccentric loading of the angle, or is it assumed the angle is concentrically
loaded and designed accordingly?
