The plastic moment capacity is defined as 500kNm for piles but it is exceeded considerably without the forming of plastic hinge in dynamic analysis.
The definition of plastic moment capacity:
The moment values at X axis and 500kNm limits by red marks:
Time step is 1.083e-4. I thought that it might happen only at the time step passing instant. However, the moment values are getting increased even after the time steps at which the closest bending moments to the plastic moment capacity is passed. You can see it from the following “Time step – Moment” table.
What can be the reason? Is there any way to take at least 519 value (the value coming right after 500)?
519 is OK but 581 is too much. It is 16% greater than the value chosen.
Could you help me please?
