Jambs/Lintels
(OP)
Folks,
I am wondering how you approach designing the framing around an opening in masonry construction. I live in hurricane country and getting masonry to work for 10' heights becomes difficult when the openings are big.
How do you assume the load distribution around the opening? Do you assume the glazing on the opening to have a two-way behavior and distribute the loads to the framing elements (namely the jamb/header beam) based on a yield line of sorts? Or do you use a tributary width to design the lintel/tie beam and then design the jamb/wind column for a point load from the lintel?

I am also in hurricane country and masonry design gets a little ridiculous, so I will look at it every way possible to get a sensible design. The old south florida concrete tie beam/column method has preformed and I can't get the numbers to work for the unreinforced portion of the masonry, so being liberal with my analysis for reinforced masonry can not be too bad.

To me the tough question is as ash060 said how much masonry can you count on to resist the resulting loads. Maybe h/3 at the most seems about right to me unless that starts to look wrong. You get to a point where you have to put in either a masonry pilaster or a concrete column.
