Press Machine
(OP)
Hi everyone,
Please see attached image, is it an uplift or downward reaction at points A & B? It looks so easy that a simple equilibrium of forces can solve it but i'm confused. I'm thinking of a push-pull interaction at the base, am i right?
Thanks for the help.

Did you mean i need to design my foundation based on the weight of press machine only? Have you done some kind of analysis like this before or do you know any related article regarding the design of press machine foundation?
Thanks
RE: Press Machine
You might get some incidental rotation at that point.
Design for seismic, for wind, for eccentric loads being loaded onto the platform, etc.
RE: Press Machine
Ok i think i'm getting closer. So do you mean i can anchor this press machine even on a normal ground slab as long as it can take the weight of the machine only? And do you know any article or worked example regarding this topic that i can look into as reference kit? Thanks for the help.

The problem with sloppy work is that the supply FAR EXCEEDS the demand
RE: Press Machine
Maybe a way to visualize this would be to stand on a scale and determine your weight. Then squat all the way down and raise back up. Watch your weight through the process. The number on the scale (assuming slow fluid movement) should not change significantly.

thanks again guys, 😊
RE: Press Machine
If you cut and removed the horizontal lower beam from the press frame that supports the test piece such that the test piece now rests directly on the floor, then you would need a "strong floor" to resist the testing actions, along with suitably designed tension connections between the strong floor and the vertical legs of the revised press frame.

Yup i agree with that but i'm afraid i will not be able to calculate that or derive that horizontal shear. This is actually my first time to design foundation carrying machine and first thing i need to know is the loading (not to include dynamic or lateral thrust). I got all the technical specifications of the press machine and initially came up with foundation design (size & reinforcement) purely based on self weight only. Another thing that i'm thinking about is how can i explain to our client that the foundation is intended to support the weight of press machine only (draw an FBD and explain to them?).
But i do strongly believe that all of the above comments are correct (100%) but the question i'm ahead of is " How can i prove to our client (mostly non-technical guys) that it is like that? So any "Research works/worked examples/" might be of great help for them.
Cheers
