Re: Shearer Home Addition–Vent Openings in Stem Wall
Vista Structural Engineering, LLC,was asked to address an issue with regards to continuous horizontal rebar being
interrupted by vent openings at two locations in a stem wall.At these two locations,the 2x12 rim can span over
the 2'-0"vent openings(see calculations attached), and the floor joists can be attached to the 2x12 rim with
Simpson LUS28 hangers(see detail attached).The horizontal rebar in the stem wall that stops at the vents is
primarily for temperature and shrinkage;therefore,we recommend approval of the discontinuity of the horizontal
rebar at each side of the vents.The rim that spans over the top of the vents provides the structure needed for
support of the imposed design loading.
Our firm appreciates the opportunity to serve you. If you have any questions or if you need anything further,
please feel free to contact us.
Sincerely,
