Committee Action:
Question 1: The draft 2007 FBC, Section 1609.4.3 Exposure C requires a 20% increase in roof sheathing uplift and roof to wall uplift loads, in certain wind exposures.
Is it the intent of 1609.4.3 to increase the entire continuous uplift path by 20%?
Answer: Yes. In order to provide for a continuous load path transfer to the foundation as required by Section 1604.9 of the 2007 FBC, building, the 20% increase in roof sheathing uplift and roof-to-wall uplift loads must apply to the entire load uplift path.
Question 2: If “Yes” to question 1, is it the intent to increase the load capacity of roof trusses by 20%?
