Shell structure buckling analysis
Shell structure buckling analysis
(OP)
Hello,
I would like to perform a buckling analysis of a thin concrete doubly curved shell structure (architectural / structural). I am writing my own code and as a shell element I am using a combination of a plane stress triangle (for membrane forces) and DKT triangle (for plate part of the stiffness matrix). Linear analysis works well, but for buckling analysis I am missing a geometric stiffness matrix for DKT element.
Do you know some good reference where I can find more about how to construct geometric stiffness matrix for DKT elemets ?
Thank you !
