Are there deflection limits for cantilevers?
Are there deflection limits for cantilevers?
Building codes may have prescriptive limits.
AF&PA's Wood Frame Construction Manual (WFCM) for One- and Two-Family Dwellings prescriptively limits cantilevers based on the following conditions, where L is the length of the simple span, center to center of bearing and d is the depth of the joist:
Loadbearing wall, shearwall or non-shearwall <= d
Non-loadbearing, shearwall or non-shearwall <= L/4
Non-loadbearing shearwall <=4d
