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.

2 dead load suspended ground floor with no partitions above 0 25 kn m. These spans were calculated using our floor joist calculation engine. The example diagram below from the summary section shows a two span continuous beam with a linear distributed patch load and point load. 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.
