Hi All,
I was called by a potential client about a project. There is an old building that is being remodeled, the roof structure replaced of which the trusses will be supported by a ~10' tall HCMU Wall, keep in mind the building has been in this condition for some time now. The client discovered that the wall cells are all ungrouted, no rebar was installed within the cells or extending from the strip footing into the cells. The permitting department wants an engineering review done on the wall and if needed a repair proposed.
Thinking out loud, the wall will likely pencil out axially once grout is added but fail in flexure. At a minimum we will need to grout the cells to allow proper fastening of the Sill Plate for attaching the trusses. Simply grouting the cells may not be enough, for the overturning moment where the cells attach to the footing, are their external fasteners that can be used to attach the concrete wall to the strip footing? I'll have more info on the project next week, what are your guys thoughts on how you would approach this?
TIA
