Hi,
Could you fix the definition of parameter gamma in HHT integrator ?
I think it should be changed to $alpha.
And alpha has different to the conventional one.
alpha (opensees) = alpha (conventional) + 1
So to get the same results with Newmark-beta method, alpha should be 1 in opensees.
If I'm wrong, please let me know it.
Regards,
HHT Integrator
