foundation design for a 1000 ton press, what is the load?
hi guys,
i ran into this foundation design for a 1,000 ton press. i am just curious what is the design load i should use:
i understand 1,000 ton is the press capacity. however, should i design the ftg for a live load of 2,000 kips???
check out our whitepaper library.
the 1,000 tons will be an internal load and will not be transferred to the footing. one caveat is if the load is applied very quickly and there are inertial loads. other than that, the foundation should be designed for the weight of the machine plus what's being pressed.
if you "heard" it on the internet, it's guilty until proven innocent. - dcs
get the operating weight from the manufacturer. no need to second guess what the machine is doing.
thanks guys.
i got this "equipment dead load of 100 kips plus 50% impact" specification. so i only need to consider 150 kips dead load in design? no more live load?

get a copy of aci publication 351.3r-04 "foundations for dynamic loads". also be sure to get all the information the manufacturer can give you including any special design parameters, as others have suggested.
do you have any photos or diagrams of the press? normally, that's a machine with upper and lower beds, and that force is exerted between them, not between the machine and the foundation.
one example here:
