　　With the continuous improvement of the shelf market requirements for shelves, the recent shelf manufacturing Co., Ltd. designed a "steel shelf" below is its design principle:

　　First, the load-bearing components of the shelf structure should be designed according to the bearing capacity limit state and the normal use limit state, and the non-load-bearing components should be set according to the structural requirements.

　　Second, the safety level of the shelf structure is generally recommended as three levels, and the safety level of the shelf structure with special requirements can be determined separately according to the specific circumstances.

　　3. The limit state design method based on probability theory is adopted in this specification, and the fractional coefficient design expression is used for calculation.

　　4. When designing the shelf structure according to the limit state of bearing capacity, the load design value and strength design value should be used; When designing the shelf structure according to the normal use limit state, the standard load value and allowable deformation should be calculated.

　　(5) Except as otherwise provided in this Code, the standard load value, the value of the load component factor and the value of the load combination factor used in the calculation of the shelf structure members and connections, as well as the load effect combination, shall comply with the provisions of the "Building Structure Load Code" (GBJ9-87); The internal force and deformation of the structure can be determined by the method of structural mechanics. The section selection should be in accordance with the specification for the Design of Steel Structures (GBJ 17-88) or (and) the Technical Specification for Cold-formed Thin-wall Steel Structures (GBJ 18-87).
