Verification with Sap2000
Posted: Fri Jul 29, 2022 7:46 am
Hi all and hope ur well,
I am comparing a simple portal frame in sap2000 with the corresponding in OS and I am getting several slight differences in modal analysis.
When I am running in sap2000 a response spectrum analysis with 5% accidental eccentricity and compare with the ASDEA algorithm the results in torsion differ a lot. When I take out the 5% eccentricity from sap2000 results become similar. Is there any chance we could get the algorithm to give the option of including the 5% eccentricity as per code EN1998-1 ยง4.3.2.
