I'm working with S-Frame and I have a dead load and a moving load for a bridge crane. See photos attached. The deflection I'm getting makes no sense. It's showing discontinuous deflection. See photos.
Hi there,
Thank you for getting in touch. I see you created a separate technical support case for this issue, and shared that you were able to resolve this after rebuilding the model.
I am wondering if this model may have had duplicate joints, or member disconnects at some of these discontinuities. One way to confirm if this is the case is to run an unstressed vibration analysis, and observe the mode shapes. This can help validate if your model boundary conditions, and member connectivity is aligned with your intention, in the absence of any external loads that may be added later in the modeling process.
Feel free to reach out if you have any further questions.
