Topic: Change Displacement in each step

Hi, is there any possible way to change the displacement applied to the structure in each step in ATENA GiD? For example, set 0.0001 displacement in step 1-50 and set 0.0003 in step 51-100. Thank you.

Kind regard,
Jia

Re: Change Displacement in each step

Dear Jia,
one solution is to divide the displacement in 2 Intervals (Int 1. with Steps 1-50, Int 2 with Steps 51-100).

Another is to use "Define Loading History" instead of "Generate Multiple Steps" in Interval Data.

Yet another to use a Function for the prescribed displacement definition.

Regards.

Re: Change Displacement in each step

Thank you for your reply. How can I divide the displacement in several intervals in ATENA GiD? When I choose "Interval Data" and choose the "Define Loading History" and "Manual", what is the next step? I change the number at column LocalStepIndex, but when I analyse it in ATENA, there are only four steps. Thank you.

Kind regard,
Jia

Re: Change Displacement in each step

Ad Divide: create a new Interval, choose to copy the Conditions from the existing one, adjust the multipliers and numbers of steps in both Intervals.

Ad Manual Loading History: read the help bubbles, add + define the Step Multipliers. Do not try to make any changes in the first (read only) column.

Regards.
