Dear engineers,
I modeled a building in ETABS, and under wind loading, then I got the result of story response forces like this.
The semi-rigid is assigned, and the slab are flat slab.
I wonder why the overturning moment and story shear force reverse the value from negative to positive value at certain story as I highlighted.
Is there any problem with this? what caused that problem?
Thank you in advances for your ideas.
