RE: Concrete or Masonry Infill

[Subject Prev][Subject Next][Thread Prev][Thread Next]



Do you know if it’s fairly easy for a contractor to accomplish this? I’ve heard quite a bit of complaining when I suggested it so I assumed that it was prohibitively difficult.

The way you’ve thought of is the way I’d do it.

I’d like to solicit opinions on approaches for infilling openings in reinforced concrete or masonry shear walls such that the existing wall and infill will act as one unit. To develop the capacities of the reinforcement with epoxy seems to be a commonly used method but how does this develop the load into the existing reinforcement? If the new rebar is not fully lap spliced with the existing rebar can the new section of wall be considered as being effective?


The only way I’ve been able to think of doing it is to dowel the new bars into the existing wall far enough to develop a lap splice with the existing bars. That requires an awfully deep hole, however, and seems prohibitively difficult to construct. Any suggestions are appreciated.
