High Frequency noise in dynamic analysis

Post by Prafullamalla » Tue Mar 10, 2020 10:52 pm

For a couple of months, I was working on dynamic analysis of shear wall building with bolted connection. Now, I find high frequency noise in the model. The model result is in good agreement with the shake table if I take damping ratio as high as 40%. Is it possible to remove high frequency noise in other way taking damping just about 5%. here is the result with 40% damping.
