One, the value of the standard value of the constant load:
Calculated according to the building practices and the size of the components used to be calculated in accordance with the actual situation; or load, general civil buildings, such as residential, office buildings, such as the value of 2kN/m^2, such as canteens, such as the value of 2.5kN/m^2, see the "Code for Structural Loads of Buildings" GB50009-2001<
Two, the basic provisions of the standard value of building loads:
The structural loads can be divided into the following three categories:
Permanent loads, such as structural self-weight, earth pressure, pre-stress, and so on.
Variable loads, e.g., floor live loads, roof live loads and accumulated dust loads, crane loads, wind loads, snow loads, etc.
Incidental loads, e.g., explosive forces, impact forces, etc.
Note: Self-weight is the load generated by the weight of the material itself (gravity).
Different representative values should be used for different loads in the design of building structures.
Standard values should be used for permanent loads.
Variable loads should be standardized, combined, frequent or quasi-permanent according to the design requirements as a representative value.
Occasional loads should be determined according to the characteristics of the use of the building structure as a representative value.
