For example historically uk office buildings have been designed and marketed with live loadings of 3 5 4 0 kn m2 however this may be an over provision.
Floor loading calculation uk.
Find the column for your dead load and spacing and the row for your timber size to find the permissible clear span in metres.
This span table is to the format and methodology given in bs 5268 7 1.
Click on a span to generate a full calculation you can adjust the exact span.
However you should consider the weight of the raised floor in the floor loading formula.
A typical wood frame floor covered with carpet or vinyl flooring has a dead load of about 8 pounds per square foot.
However if the attic is intended for storage the attic live load or some portion should also be considered for the design of other elements in the load path.
Once the loading and geometry have been specified the calculator automatically uses the clearcalcs finite element analysis engine to determine the moments shear forces and.
If there s wall board covered ceiling suspended from the underside of that floor the dead load increases to about 10 pounds per square foot.
Load types loads used in design load equations are given letters by type.
2 5 kn m2 for floors above ground floor and 3 0 kn m2 at or below ground floor over may be more appropriate with 7 5 kn m2 over 5 of the floor area to allow for future flexibility.
For example if you have joists spaced 40 cm 16 inches on centre with a span of 4 2 metres 14 feet the load would be 462 kg 1 019 lb per joist.
We do not consider this in the calculation of occupancy.
Floor loading calculations help you make better racking decisions.
Suitable for uk building regulation approval.
In the calculations we assume 95 of the floor area is loaded to the value your provide in the uk it is standard practice to apply a higher floor load of around 7 5kn m2 over the remaining 5 of floor area.

And if you don t calculate correctly you ll have an expensive repair on your hands.
2 dead load suspended ground floor with no partitions above 0 25 kn m.
The example diagram below from the summary section shows a two span continuous beam with a linear distributed patch load and point load.
Used but they typically defined the load cases or combination stress or strength limits and deflection limits.
A floor loading assessment is the evaluation of the concrete subfloor not the raised floor.
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.
The dead load on a floor is determined by the materials used in the floor s construction.
Calculations to bs 5268 2 2002.
These spans were calculated using our floor joist calculation engine.
