Dear ALL,

In rafter supported roof, there is a compression ring present, like shown in the attachment. Can anyone help me with the calculation for this compression. Which criteria, or any reference can be used for this.

Regards,
Inam

There are some load cases for circular rings in Roark's Formulas for Stress and Strain that might be of use.
