bending stiffness

(OP)
Hi everybody,

Im using an all purpose FEM software package. I would like to know how to estimate a bending stiffness of a beam which has a very complex cross section and  several cuts along the main beam axis. I made the sketch, extrudet it, done the cuts and meshed as well. I know of course the E-modulus of the material too. I tried to apply a uniform deformating force at one end obtained deflection but i don't know how to evalate the result stiffness. thanks for any clues,

best regards,

jungus
