Factor of Safety on Scaffolding
Factor of Safety on Scaffolding
(OP)
I have a question regarding Factor of Safety on steel scaffolding. The resources I find state FS=4 on the structure. It is unclear whether this is FS=4 on the yield or ultimate stress of the steel. Thanks!

Handbook of rigging: lifting, hoisting, and scaffolding for construction and ... By Joseph A. MacDonald
The factor of safety is the ratio of the ultimate stress to the allowable stress:
FS = Ultimate Stress/Allowable Stress
Where:
•Ultimate Stress: is the maximum stress which a member can withstand before failure (can be tensile or yield strength)
•Allowable Stress: is the maximum stress which a member is designed to handle

Regarding A36, is the compressive yield strength 36 ksi as well as tensile?
RE: Factor of Safety on Scaffolding
per 1926.451(a)(1) each scaffold and scaffold component shall be capable of supporting without failure, its own weight of at least 4 times the maximum intended load aplied or transmitted to it
