Seismic Code

Vessel Characteristics

Period of Vibration Calculation

The fundamental period of vibration T (above) is calculated using the Rayleigh method of approximation:

T = 2 * PI * Sqr( {Sum(Wi * yi2 )} / {g * Sum(Wi * yi )} ), where

Wi is the weight of the ith lumped mass, and

yi is its deflection when the system is treated as a cantilever beam.

To obtain V, take the greater of V(32-2) and V(32-3).

Then take the lesser of this and V(32-1), and divide by 1.4, giving 7,198.27 lb (3,265.08 kg)
