Heel Blocking Requirements and Capacity Analysis

Both the International Residential Code (IRC) and the International Building Code (IBC) require that the top plates of exterior braced wall panels be attached to the rafters or roof trusses above. This report will discuss the code requirements and provide alternate engineered designs and capacities, including heel/bird blocking, partial height blocking and blocking panels.

Overdriven Nails in Structural Sheathings

All building codes provide provisions for the attachment of structural sheathing to wall and roof framing members. In almost every case, the published capacity of the sheathing and fasteners assume the head of the fastener is flush with the surface of the sheathing. This Research Report discusses guidance when fasteners are overdriven.
