Floor laod capacity. 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. Knowing the load rating of the platform and the column spacing of the platform are two critical metrics. 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. Maximum floor joist span for no.

Floor capacity depends on the thickness of the concrete as well as the compression rate of the soil underneath the slab. This is also an acceptable method for figuring out the load bearing capacity for small home projects like a driveway or a garage slab. Floor load capacity is the total maximum weight a floor is engineered to support over a given area. Floors must be capable of bearing both dead and live loads.

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. Used but they typically defined the load cases or combination stress or strength limits and deflection limits. It is measured in terms of pounds per square inch.

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. 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. You can however calculate the load capacity of concrete in a quick and general way.

2 grade of douglas fir are indicated below. 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. It is expressed as pounds per square foot.

1 psf lb f ft 2 47 88 n m 2. Dead load weight of structure and fixed loads 10 lbs ft 2. Load types loads used in design load equations are given letters by type. Dead loads are the weight of the building materials the floor is holding up.

This will tell you if you if there may be a problem in the project plan that needs the expensive attention of an engineer. Span calculator for wood joists and rafters also available for the android os.
