thank you for the help, I have Split the top and bottom headers and I was wondering do I just need to select just one face from each split when adding the joint? nI have also ran the program and it has fainly given me a result. the deflection is much larger than expected. I was wondering is there a given stiffness with the joints or do I need to apply one? I am also being told the boundry box is too small and that I should turn on Large deflections in more than one warning.nThanks againnn
