Output. Structural Nodes. Displacements. IDA

Post by queren »

I’d appreciate your help.
I’m running an IDA. The increase in the scale factor was set to 0.1, the initial factor 0.1 and the final factor 2.5. The problem I have is when I want to check in the output the displacements of the structural nodes only appear the displacements of the nodes in the increments from 0.1 to 0.9. After scale of 1.0 to 2.5 I can't see the node displacements.
Thanks in advanced

I can think of two possible reasons:
- If you are using an older version of SeismoStruct (v2023 or older), these are 32-bit programs, and are able to read files up to 2 GB. If your output file is larger, the program is not able to read the data after that threshold.
- If you get divergence in the analysis with the scaling equal to 0.90 the program does not continue the analyses any further.

I’m using the 2024 version.
I can see results in the Step Output. The problem is that I cannot see the displacement results in the nodes of the last increments, specifically in the Global Response Parameters > Structural displacements

What do you get? If you select the analyses with factors >0.90 what do you see in the Global Response Parameters > Structural displacements?
