Hi there,
I am analyzing a conveyor structure in sap2000 and its maximum height is 10m.
Every thing such as stresses displacements and ... are normal and structure is stable, but,
For modal analysis, I set maximum number of steps equal to 300, but even with this number of modes, in the Modal Participating Mass Ratios table, maximum vale of SumUx and SumUy is 0.77.
Can you help me with this problem?
