Floor loading calculation uk.
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.
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.
Suitable for uk building regulation approval.
The example diagram below from the summary section shows a two span continuous beam with a linear distributed patch load and point load.
We do not consider this in the calculation of occupancy.
2attic loads may be included in the floor live load but a 10 psf attic load is typically used only to size ceiling joists adequately for access purposes.
These spans were calculated using our floor joist calculation engine.
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.
A typical wood frame floor covered with carpet or vinyl flooring has a dead load of about 8 pounds per square foot.
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.
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.

And if you don t calculate correctly you ll have an expensive repair on your hands.
Used but they typically defined the load cases or combination stress or strength limits and deflection limits.

2 dead load suspended ground floor with no partitions above 0 25 kn m.
Calculations to bs 5268 2 2002.
Floor loading calculations help you make better racking decisions.
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.
A floor loading assessment is the evaluation of the concrete subfloor not the raised floor.
Find the column for your dead load and spacing and the row for your timber size to find the permissible clear span in metres.
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.
Calculate the maximum load in kilograms that one of your floor joists can support.
