diffrent period between etabs and opensees

Post by javadgholamrezaei » Thu Mar 01, 2018 2:43 am

hi all

I have modeled a reinforced concrete frame in Etabs and OpenSees which contains 4 floors and 3 spans.But the period of frame in OpenSees is about 30 percents less than Etabs.In other hand by using the IDA analysis in OpenSees the relative drift of floors results approximately zero.please help me
