-> float Parameters
- ct Double (Optional)
- Optional, default 0.05. Coefficient for estimation of fundamental period from EC8 4.6: T1=ct*H^(3/4)
- direction Byte (Optional)
- Optional, default 0 (no specific direction). Direction of the seismic action to get proper period
Return Value
DoubleThe first period of the model
