Would an A-35 be suitable for the rafter>top-plate connection shown here? Would I need one on both sides of a rafter, or just on one side? Existing structure (grey) is 12'x 18', 6" CMU block w/rebar, located in Central California (seismic zone). Essentially putting a new "hat" on the building which will be a small sleeping loft, want to make sure everything is to code, particularly hardware connections. General advice as to fastener/connection details is also greatly appreciated. (i.e. Would simply toe-nailing into the top plate be suitable? Are framing-angles even necessary for transferring horizontal loads/preventing shear in this instance?) Thanks All!
