Determination of "connection rigidity percentage"
Determination of "connection rigidity percentage"
(OP)
Hi dear members
For a steel horizontal frame( H shape),I want to analyze the forces & momentums.
But I do not know how we can determine the percentage of connections rigidity.in the other words let's think we connect the middle beam(in H frame)to the sides beams by some bolts in their webs.As you know,this connection is not completely rigid ,but it can bears some momentum too.
How we can analyze it?We must design it as a rigid connection or not?
Respects.

RE: Determination of "connection rigidity percentage"
If you absolutely have to, provide slip critical bolts and do a quick check in the green book using the "C" charts for eccentrically loaded bolt groups in section 4. This will give you a moment capacity, but not a "stiffness". The stiffness has more to do with moment-rotation than moment capacity. Using a simple shear connection, you generally don't get more than 20% end moment.
