Murray's Acceptability Criterion Analysis Procedure 1. Estimate the total amount of damping available.
Murray's Acceptability Criterion Analysis Procedure 1. Estimate the total amount of damping available.
Lower limit for thin slab of lightweight concrete; upper limit for thick slab of normal weight concrete.
Lower limit for hung ceiling; upper limit for sheetrock on furring attached to beams.
- Mechanical Systems: 1-10%
Depends on amount and attachment.
If attached to the floor system and not spaced more than every five floor beams.
If damping > 8-10%, beam is O.K. If not continue with the procedure.
