Isolation Joint
Isolation Joint
(OP)
Falks,
Recently I visited a very long building in which structural engineer has allowed some isolation joints. Said joints had been perished due to unknown reason. I am looking for a suitable joint details for this. If someone could help me with this, it would be really appreciated.

Sorry if this is confusing. That cracked beam is a long cantilevered beam. This is the isolation joint they had used.

So what we are looking at in the photo is the end of a cantilever beam where some plaster? finish was placed to bridge over the joint and due to natural movement in the building the exterior finish cracked...which would be expected right?
Can you clarify what you are asking relative to a "suitable joint detail"?
Are you wondering how to rebuild the joint on the top surface?
RE: Isolation Joint
Yes, I'm thinking of rebuilding the joint on the top surface. There should be a better way than just plaster???
Many thanks,

RE: Isolation Joint
One concept is to use an expansive neoprene joint filler. There are also expansion joint assemblies that you can buy that sit in slots cut into either side of the joint in the top surface of the concrete.
Try this site: http://www.c-sgroup.com/expansion-joint-covers
Also see the attached for a compression seal type joint.
