Follow Bolted joint comparison to Eurocode - 2
Peter, I read, read, read about bolts, the bolt's enginerring stress. But the problem is the same, I could not see the plasticity occurring in the graph Moment X Rotation.
1 First point, I do not agree when the people specify tightening a fastener to its yield point. Because I see it as a problem, whcih tease the yiled point in the other components, as column and end plate, before that it shall occure.
2 Second point, comparing with eurocode, it is similar, but I would like to see the point which change the stiffness, or in the graph the inclination, the plot shall not be linear.
3 Third point, I think taht it occures because the bolt pretension is so high, but it is the minimun normative loads. So the yield shall not ocure.
4 Fourth and last point. I think that the problem is in the egineering stress in the bolts.
Is attached: the graph moment rotation results, the engineering stress table, the lecture which I took the engineering stress, and the model. And finnaly the mathcad that I did, to comparte the graph moment X rotation.
If anybody could help me, I would be greatful.
