AREA REQUIREMENTS

[Francis Vineyard]

". . . for the duration of time indicated by the required fire-resistance rating . . ."

"The code is very clear that fire walls should remain in place for the expected time period. Therefore, structural failure on either side of the wall shall not cause the collapse of the wall" during the minimum time period.

Follow-up question: is it possible to have a 2-hour single-stud fire wall (fka area separation wall) that can still have a floor collapse on one side without damaging the structural integrity of the wall itself?
How would you do the floor/wall junction detail for WP3910 (below)?

You do not use "this detail" at a "building separation"
Nor would you use it for a townhouse wall. (a floor collapse on one side without damaging the structural integrity of the wall itself)
