KL/r > 200 for compression member
KL/r > 200 for compression member
(OP)
I have a V-brace that is an LL3x2x4x3 & receive the slenderness ratio error for compression. What values for r is Risa using? For this particular size I calculate 15'8" max length to satisfy the KL/r >200, but Risa is telling me its 14'-8". Also if I define the member using Euler buckling will risa use kl/r > 300?
Thanks!
Thanks!





RE: KL/r > 200 for compression member
When the member is defined as a tension only member (Euler members are a form of tension only members) then the program will look at L/r>300.
Both of these checks can be turned off, if desired, by going to Tools - Preferences - Solution and Results. Then Checking the box which says, "Allow KL/r>200, L/r>300 for LRFD, CAN steel design?"
