Good Morning,
I hope you are well. I am working on sizing an isolation UMHW pad that will be placed below a beam subjected to a load of 250 kips (as shown in attached PDF). Based on the triangular load distribution principle, I expect the load to be distributed over a certain area. My original plan was to compare the generated bearing stress with the allowable compressive strength of the material. However, I am concerned that this approach does not account for the thickness of the pad. Given the heavy load, I am worried that the pad may get crushed under compression.
My question is:
- Is there any formulation / guidance / standard of practice containing information about sizing the pads?
