Hi
I'm using the software ROBOT to make a time history analysis. When I put displacements on the supports the results are OK. My problem is when I change them to accelerations and change the time history analysis method from Newmark to Newmark with acceleration.
I am pretty sure that the results should be similar beacause the displacements that I use have a sine curve variation over time, and the acceleration is the second derivative of the displacement.
Thank you
