Kpa of concrete
WebAll unfixed items in a building such as people and furniture result in a 'live' load on the structure. Live loads are exerted in the vertical plane. Live loads are variable as they depend on usage and capacity, therefore the AS 1170 table provides allowances which are based on conservative estimates. For example, the live load for a floor in a ...
