Floors must be capable of bearing both dead and live loads.
Floor laod capacity.

In other words it refers to the capacity of an access floor system to continue to perform its intended function when supporting a specific amount of weight.
Knowing the load rating of the platform and the column spacing of the platform are two critical metrics.
Load capacity refers to the maximum demand stress or load that may be placed on a given raised floor system under normal or otherwise specified conditions for an extended period of time.

Dead load psf span calculator for wood joists and rafters available for the iphone.
It is expressed as pounds per square foot.
Dead load weight of structure and fixed loads 10 lbs ft 2.
For example a floor joist at 16 spacing s that can carry 53 pounds per linear foot would translate into a 318 pound single point load at its center.
Dead loads are the weight of the building materials the floor is holding up.
2 grade of douglas fir are indicated below.
This is also an acceptable method for figuring out the load bearing capacity for small home projects like a driveway or a garage slab.
Floors are engineered to carry a maximum static load and a maximum dynamic load that can t be exceeded without the risk of compromise to the structure.
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.
Floor load capacity is the total maximum weight a floor is engineered to support over a given area.
Used but they typically defined the load cases or combination stress or strength limits and deflection limits.
Maximum floor joist span for no.
A uniform load rating on a beam can easily be translated into what an equivalent maximum point load can be.
The interior columns of the platform will always bear the most weight since they support most of the.

Floor load capacity is a measure of the amount of weight a floor can hold while also preserving its structural integrity.
D dead load l live load l r live roof load w wind load s snow load e earthquake load r rainwater load or ice water load.
Live load is weight of furniture wind snow and more.
Floor capacity depends on the thickness of the concrete as well as the compression rate of the soil underneath the slab.
This will tell you if you if there may be a problem in the project plan that needs the expensive attention of an engineer.
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.
