RAM CONCEPT - Actual stress and Demand stress
Hi everyone, I got a question regarding the stress in RAM Concept.
Is the Demand stress = actual stress - capacity stress (section capacity) or Demand stress = Actual stress.
Notes: Actual stress is stress in section due to loadings and PT action…
How Strain is converted into Displacement (Purpose is to find the initial value)
Hi all,
This may be the basic question but need to know that.
Question => Strain is the change in the dimension over the initial one , so it is provided as the percentage or fraction. In Plaxis stress will be derived from the induced strain and the…
Corner stresses and utilization ratio
Hi,
I have a question regarding utilization ratio and corner stresses in the model.

Multilinear Stress-Strain Curve
Excuse Me, I'd like to ask a question
For Collapse Analysis, when we define material properties for Multilinear Stress-Strain Curve, is it true strain or engineering strain that we should consider?
Thanks in Advance.
Von mises stress how it can be calculated and compared with staad pro values
Hello dears,
I used recently STAAD Pro for analyzing a steel plate, anyway as we know the result of Von mises stress to be compared with Fy of the steel plate,
Von mises stress = 0.707 sqrt((smax-smin)^2+smax^2+smin^2) the result given is less than…
