great, thanks alot !

didn't know that the roof sheathing can act as a horizontal diaphragms... I thought that, in the U.K. for example, the brick wall is assume to be fix to the ground. and than there is a static scheme for the roof.

ok,then structures of this kind (in the video) must have a horizontal diaphragms ? https://www.youtube.com/watch?v=BtsZk0UR2EI&t=512s

well obviously you're common proofs that you're not a structural engineer

thanks for the recommendation! the shape of the mechanism you have described is exactly what I was thinking. but i think that it works as a three dimensional structures and that's what's keeps the stability. I think you are right about the Unequal loading due to wind. but what about all the...

am just looking for a book on the subject of compression ring. i dont have any plans. and as i said, the shape of the roof is trapezoid.

its trapezoid. its not a shell the ring is made of beams.

anydone ....?

actually there is no couple action on the basement wall, the slab on the ground floor don't have shear capacity to create that action ( its not stiff enough like outrigger).

Hey am looking for a guide/book/something to read on the stability of ring action. mainly of trapezoid shape roof. somthing like this thanks !

dosent the force need to be lifted at the face of the suppor (in the part of the beam that is wider then the wall) like this

yes, its a transfer beam. and yes the dashed outline is the heavey load. there is a slab east and west. the width of the beam is 150 cn and the height is 200 cm. the shear stress is ok but how can i know that in the vicinity of the suppor,the entire width of the beam will be utilize. my...

Hey everyone I have this case where the beam is wider then the support. Normally due to heavy concentrated load on the beam ( transformation beam) there is the potential of shear compression failure. In order to prevent this type of failure- increasing in the width of the beam will increase...
