Time History Proportional Damp Data

Interpolated Damping Data Options for Time History Load Cases

Inputs

Name	ID	Description	Type
Damping Type	T	Proportional Damping Type: (0=DAMP_BY_DIRECT_SPEC 1=DAMP_BY_PERIOD 2=DAMP_BY_FREQ)	Integer
Damp a	Da	The mass proportional damping coefficient. This item applies only when DampType = Direct Spec	Number
Damp b	Db	The stiffness proportional damping coefficient. This item applies only when DampType = Direct Spec.	Number
Damp f1	Df1	This is the period or the frequency (depending on the value of the DampType item) for point 1. This item applies only when DampType = Damp by Period/Freq	Number
Damp f2	Df2	This is the period or the frequency (depending on the value of the DampType item) for point 2. This item applies only when DampType = Damp by Period/Freq	Number
Damp d1	Dd1	This is the damping at point 1 (0 <= Dampd1 < 1). This item applies only when DampType = Damp by Period/Freq	Number
Damp d2	Dd2	This is the damping at point 2 (0 <= Dampd2 < 1). This item applies only when DampType = Damp by Period/Freq	Number
