Figure 5-11 Comparison Of The Predicted Vs. Actual Post-Yield Stiffness Of The Connection With ±5%
Error Envelope For The Category-1 Connections With Circular Bolt Pattern
The results presented in Figure 5-12 show the predicted ultimate rotation capacity of the connection
versus the actual rotation capacity of the connection at failure. A close examination of these results
reveals that majority of data point fall in between ±5% error envelope, which shows close agreements
between the predicted and calculated values.
