According to the structural load specification GB 50009-2012, the standard value of roof live load is 2.0KN/m^? and 0.5KN/m^? ; floor live load standard value of 2.5KN/m^?
Live load is in the design of the base period, its value changes with time, and the change value and the average value of the load can not be ignored compared. Usually, it is the use or occupancy loads caused by people, materials, and transportation, and the naturally occurring natural loads.

Load combinations
Load combinationLimit state design of load carrying capacity or limit state of normal use according to the standard combination of design, variable loads should be used in accordance with the provisions of the combination of standard or combination of values as a representative value. Variable load combination value, should be variable load standard value multiplied by the load combination value coefficient.
Normal use limit state by frequency encounter combination design, should be used frequency encounter value, quasi-permanent value as the representative value of variable load; quasi-permanent combination design, quasi-permanent value should be used as the representative value of variable load. The frequency value of variable load shall be taken as the standard value of variable load multiplied by the coefficient of frequency value of load. Variable load quasi-permanent value shall be taken as the standard value of variable load multiplied by the coefficient of load quasi-permanent value.
