Abstract: Recent changes to the requirements for roof-to-wall connections in the 2009 International Residential Code (IRC) for high wind and seismic areas, and for roofs with high heel trusses, include additional detailing requirements for fastening, blocking, and knee walls. These new requirements, however, have not been optimized from the performance standpoint to account for the contribution of system effects from components such as roof sheathing and hurricane ties/clips. The new additional requirements also lead to added cost and time of construction - an issue that is particularly important to the construction industry because of the rising use of high heeled roof trusses to meet increasing energy efficiency standards.
