I have a client that wants to install a window in an existing block wall. what is the best way to install reinforcing steel around the opening. I have called out for a steel frame around the window and drilled 24" all thread epoxy anchors around where the code asks for extra steel. is there a reference book for this out there or any suggestions.
This is in a 1974 era building -soild grouted and minimal steel -wood roof and 2nd floor - in seismic zone 4 - I am checking that I have enough shear wall.
