Calculate concrete slab load capacity.

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. This is a terrific concrete slab calculator for estimating how many cubic yards to order to complete your concrete slabs concrete floors concrete walls and concrete footings. This free concrete calculator estimates the amount of concrete necessary for a project and can account for different shapes and amounts of concrete. How to calculate the load bearing of concrete step 1.

Search is the most efficient way to navigate the engineering toolbox. Calculate self weight of the concrete slabs. Calculate the super imposed loads dead weight of storage tank and liquid in the same on the concrete slabs. Look in your project plans for any notes on additional rebar or wire mesh that has been added to your concrete.

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. Just remember to add some extra concrete to your total order because running short is not an option. 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. Look at the general instructions at the front of your project plans.

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.
