Bridge between new and existing building
Bridge between new and existing building
(OP)
Hello guys.
Im designing a new construction (with a terrace on top) next to existing building.
Investor would like to connect new and existing building by concrete slab - bridge.
Im wondering... it may be smart to make a dilatation of some kind between new building and a bridge. If I connect it fully (existing building + bridge + new building) I suspect that lateral load will be transfered from one building to another + new building will have torsional swing form in case of earthquake which Id like to avoid... I also have no data about existing building so id like to avoid that as much as possible.
Im even wondering about making a steel bridge, but it was said it should be concrete... i think it would be better.
Any suggestions?

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

As for steel vs concrete -- lots of considerations at play. Owner's preference rules, of course. You may be able to sway that if constructability, contractor experience, weathering concerns etc can be translated into an overall cost savings.
