wood slab braced

[Anonymous]

Hi,

please have a look on this file and tell me why ~70% of the wind load goes on nodes 72 and 86 instead of going down directly  throug the wood braces on nodes 74 and 76?

KLH145 is a kind of big plywood, 145mm thick, screwed on the beam 12 and 13. Maybe the rigidity of this connection is to high, but I don't know how reduce it.

thanks for your help

Rigidity of your slab corresponds to rigidity of 2mm steel plate.
Maybe connection between slab and beams should not be treated as fully fixed. Try to define linear releases with Ky on Uy direction
