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.
Load types loads used in design load equations are given letters by type.
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.

The dead load on a floor is determined by the materials used in the floor s construction.
Find the column for your dead load and spacing and the row for your timber size to find the permissible clear span in metres.
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.
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.

Used but they typically defined the load cases or combination stress or strength limits and deflection limits.
We do not consider this in the calculation of occupancy.
Suitable for uk building regulation approval.
Floor loading calculations help you make better racking decisions.
A floor loading assessment is the evaluation of the concrete subfloor not the raised floor.
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.
