What are standard load values and design load values? What is the relationship between the two? Which calculation methods are used for this structure?

Load standard value: the basic representative value of load, which is the characteristic value (such as average value, median value or quantile value) of the statistical distribution of maximum load in the design reference period.

Load design value: the product of load representative value and load subentry coefficient.

Relationship: the design value of load is equal to the standard value of load multiplied by the partial coefficient of load.

Used for: load specification to find standard value.

The actual design calculation usually uses the design value.

Application of load:

1, industrial buildings

In the process of production, use, maintenance and installation of industrial building floor, the load is generated by the weight of equipment, transportation tools, raw materials and finished products and the weight of operators. Heavy objects such as industrial equipment are usually local loads or concentrated loads and should be determined according to actual data. However, in order to facilitate the design, it can generally be replaced by equivalent uniformly distributed live loads that have the same effect on structural members.

2. Civil buildings

Loads generated by people, objects, furniture, equipment, etc. During the use of civil buildings. Common houses, offices, hotels, hospitals, schools, auditoriums, theaters, gymnasiums, exhibition halls, shops, station halls, waiting rooms, stacks, bathrooms, balconies and other civil buildings, the live load value is stipulated by the national load code.

3. Roof cover method

In the process of roof construction, use and maintenance, the loads generated by people, tools and correct stacking. For rainy areas, the roof live load also includes the water accumulation load caused by possible water accumulation on the roof.

Roof area ash load refers to the roof load specified in consideration of the safety of the roof structure of a factory building with a large amount of ash discharged in production. Such as foundry workshop, steelmaking workshop, sintering workshop, blast furnace, cement plant and its adjacent buildings, the gray load of housing area should be considered. The standard value of the load can be specified according to the characteristics of the ash source, the distance between the building and the ash source, the shape of the roof and the ash cleaning system.
