Geometric Non linear Structures
Geometric Non linear Structures
(OP)
Hi Forum Members,
I am designing a large span portal and after applying loads the portal is deflecting a lot. Is there any guidelines in any International code or standard, which says about a limit (Deflection) beyond which it becomes non linear behavior. I am bit confuse on this concept and large deflections and rotations will also give rise to wind dynamic loading.
Please suggest

In this way, the drifts are limited. Moreover, the story indeces are calculated as a ratio between first and second order moments. Structural codes consider linear behaviour if the story index falls within the limits they define.
