How are you doing? I'll be happy to assist you with this.
Do you have any drawings or dimensioned sketches that you can share?
hello, thanks for your reply
I'm just concerned about the lateral stability of the FF walls
You can build CMU directly on steel, but the steel needs to be sized for strength and L/600 deflection
The starter bars for the CMU should be A706 reinforcing steel and be welded to the steel beams.
The walls will also need to be braced by the roof and floor diaphragms.
If you could rate my answer, I would appreciate it. I'll be happy to answer additional questions on the topic.
Many thanks for your reply. What diameter for starter bars and what distance? Can we use light weight concrete blocks? Regards
The thickness grout and rebar size and spacing will need to be determined by someone who is being paid to design the structure.
It will depend on the loading, height, thickness, grouting, wind speed.
and the end restraint conditions.
