Online free live maximum floor live load capacity is a great engineering tool to help you calculate floor strength use it now. For 6 to 10 thick slabs on grade with k values between 100 pci and 200 pci the increase in stress i due to a 2nd wheel or post load as a percentage of stress for a single wheel or post load is approximately.

Look at the general instructions at the front of your project plans. Look in your project plans for any notes on additional rebar or wire mesh that has been added to your concrete. How to calculate the load bearing of concrete step 1. Just remember to add some extra concrete to your total order because running short is not an option.

Calculate self weight of the concrete slabs. Increasing the total weight on the floor to 4 480 pounds however results in a live load of 40 psf which is beyond the floor s load capacity. With an evenly distributed live load of 30 psf which the tables show the floor is able to support the total weight on the floor would be about 3 360 pounds. W maximum allowable stationary live load k modulus of subgrade reaction h thickness of slab s allowable extreme fiber stress in tension e modulus of elasticity.
