Through bolt connection in hollow cmu

[Reno1986]

Hello,

IS there any technical reference about
Through bolt connection in hollow cmu

I have to make a connection in existing wall and I am very concerned about it. Although Hilti provide some load capacity but my loads are higher and will require structural steel rod with bigger dia.
Any thoughts or references are appreciated

There are quite a few threads on here about through bolting in CMU and concrete. If your loads are much higher than what hilti HY270 and screen tubes can do, you might consider grouting cells solid then bolting.
