Dilatation between existing building and new extension?
Dilatation between existing building and new extension?
(OP)
Hi, Im pretty unexperienced engineer as far as reconstructions go so for some of you this question may seem stupid...
Im dealing with an extension of existing building. Extension is masonry structure with wooden roof.
Floor dimensions are cca 5 m x 3 m. Im wondering if I should make dilatation between new and existing building. Im kinda concern that without dilatation there will be some cracking between new and existing masonry wall because of soil deflections under new walls.
What do you guys usually do in situations like this?
As far as roof above extension goes... it has to be connected to existing building, but I think that timber is flexible so thats not a problem?

how about if we have existing stone walls and we anchor new walls into stone?

Otherwise, are you tying the roof together but leaving the walls separate? So when the addition sways under a wind load you're transferring load at the roof but not the base?
I don't have much experience with wood, but my first thought is to tie them together from top to bottom, and fix any cracks that may occur in the existing masonry.
