Hi,
I am modelling with fiber sections a single bay , single storey 3D frame in OpenSees and Sap2000. In both programs I am using same fiber sections and mass. The periods I am getting are
T1 = 1.53 in OpenSees and T1 = 1.30 in Sap2000. Does anyone have any idea why there is such difference?
Thanks.
period in OpenSees doesn't match that of Sap2000

Re: period in OpenSees doesn't match that of Sap2000
It may be due to the element types and number of integration points that you are using in OpenSees and Sap2000
