Disclaimer: porch for personal use (owner-builder)
I am trying to design a proposed aluminum porch, bearing on a proposed cmu knee wall (3 courses high 7.625"x3). I have the "reinforced masonry engineering handbook," and have found no examples as what I am trying to do here. Trying to make the determining factor if 3 courses fully grouted is sufficient for all the loads encountered, or do I need to make a design footer, reinforce the kneewall, use dowels, connected to existing house, etc. This is Florida, so wind loads only. The roof is composite panels that weigh 2 lb/ft^2. Additionally, the roof design requires a slope and that leaves a gap at the interior corner section as it does not align with the fascia for one of the sides of the house. I have not measured the existing slab depth yet, but it appears to be at least 6". I have seen wind design load pressures of 8 psf for screening and around 30 psf for other surfaces for 120 mph wind, excluding the roof uplift.

Anything to help me out, design sources, etc, would be appreciated.
