Masonry construction safety bracing: Typical inadequate and unsafe bracing of concrete block walls against wind, on interior of this building: (1) Single nail connections between 2x10 plank members cannot transfer anticipated loads. (2) Stake in soil (#6 rebar here) cannot support anticipated wind load. (3) Lack of connection between vertical plank and masonry prevents transfer of anticipated wind load to bracing system.
