Probabilistic Assessment of Damage from Same Shock Response Spectra due to Variations in Damping

Table 3

Synthesis of four waveforms with the same SRS.

Frequency (Hz)	100	200	400	650	950
Trial 1: proportional damping to get the same decay
Damping	0.07500	0.03750	0.01875	0.01154	0.00750
Amplitude	10	10	10	10	10
Trial 2: X3 damping of Trial 1 at 650 and 950 Hz
Damping	0.075	0.0375	0.01875	0.03462	0.0225
Amplitude	10	10	10	13.6	13.2
Trial 3: X4 damping of Trial 1 at 650 and 950 Hz
Damping	0.075	0.0375	0.01875	0.04616	0.03
Amplitude	10	10	10	15.4	14.7
Trial 4: X2 damping of Trial 1 at 100 and 200 Hz
Damping	0.15	0.075	0.01875	0.01154	0.0075
Amplitude	14	14	10	10	10
