The thermal transmittance for the area around the shelf angle is 1.162 W/[m.sup.2] K (0.205 Btu/hr*[ft.sup.2]*[degrees]F) for the effective lengths [L.sub.1] = 205 mm (8.1 inch), [L.sub.2] = 618.5 mm (24.4 inch) and [U.sub.0] = 0.287 W/[m.sup.2]K (0.0562 Btu/hr*[ft.sup.2]*[degrees]F).
For this brick veneer assembly, [U.sub.0] = 0.287 W/[m.sup.2]K (0.0562 Btu/hr*[ft.sup.2]*[degrees]F) and the linear transmittance ([PSI]) of a slab with a shelf angle is 0.5439 W/ m K (0.314 Btu/ hr*ft*[degrees]F).

Figure 2 reviews the concept of the shelf angle support typically used in the construction of residential brick walls.
The root cause is a construction defect resulting in the failure of the shelf angle iron and not settling of the foundation.
There is structural metal work that includes shelf angle
and lintel replacement.
([section])Lots of folks call them "shelf angles
," but I prefer the term "relieving angle" because it better describes their function.
Vertical expansion joints and horizontal shelf angles
are generally installed to relieve the stresses caused by these forces in large expanses of masonry; however, these items aren't always properly installed, may require repair, or may not be present at all.
Specific construction activity includes the preparation and installation of a new Tyvek vapor barrier to all backup block, as well as the fabrication and installation of new, structural steel-bolted shelf angles
On the weather side, rainwater and relative humidity can permeate the exterior surface and attack the shelf angles
, steel rebars, anchor brackets, and other structural members within.
