Murray's Acceptability Criterion Analysis Procedure
Murray's Acceptability Criterion Analysis Procedure
1. Estimate the total amount of damping available.
2. Compute the transformed moment of inertia of composite beam, It.
3. Compute the natural frequency of the beam, f.
4. Compute the initial maximum amplitude of the beam, Aot.
5. Account for the stiffness contribution of adjacent beams by estimating the total effective number of beams, Neff.
6. Compute a modified initial maximum amplitude of the beam, accounting for the stiffness of adjacent beams, Ao.
7. Compute the percentage damping required, Dreqd.
8. Compare required damping to available damping.
