Hi Sir,
a concentrated load is a virtual concept. In fact, all the loads impact in an small area with a lenght of application. It is a common simplification to consider a point for a concentrated load. And that gives a very high stresses in the area of the impact in the FE analysis. If you apply the load with 5 or 10 centimeters lentgh (what is the reality of the impact of beams or columns), you will se that teh stresses become low.
All the young engineers want to pick up all the behavior with calculation. But they forgot that everytime, it is necessary to reexamine the reality instead of the model. Remember that a calculation model is not the reality. It is a approximation of it.
And what I do is exactly what i explain.
Best regards
