Joints in continuous T beam foundation ?
Joints in continuous T beam foundation ?
(OP)
Dear Friends,
I am checking drawings for a continuous concrete inverted T beam foundation. These are two paralell beams, separeted allmost 4,60m.
Over these beams is running a Reclaimer machine. The lenght of the beams is 500 m.
Do you believe that is necessary a joint construction?. I think that could be necessary, because some differential settlement than can occur. I revised the bibliography I have , but I could not find nothing. Normally the joints contruction are applicable to super structures ( above the ground),.
I will like to read your opinions,
Thanks,

RE: Joints in continuous T beam foundation ?
Joints in super structures are generally to prevent 'uncontrolled' cracking, which is not important in a footing.
If the footing is going to experience such differential settlement that it can't cope, then it is probably not the right solution.
I've never put a shrinkage or movement joint in a footing.. however I've never done a footing 500m long!

Yes, I also is the first time to face with a long beam ( 500 m), I also never puted a separation joint in a foundation ( unless in seismic case).
Thanks for your opinion,
