What is the weight of the shelf load
The connection between the frame and the beam can be regarded as a semi-rigid coupling, and the thickness of the frame is fixed by the hinged method. Actually hinge node is packaged shelves first node method of steel structure, about welding racking system requirements as part of the first node, shelves of steel structure under any load results in theory, when the deformation of the bar, its geometry shape and position of all the stand-off is changeless, also shelf structure can be simplified as steel or truss structure, it is also a shelf steel structure by using finite element analysis can freedom of the mechanical foundation.
There is a profile that is used to the heart, and that's the way to do it. We need the shelves to find the suzhou exhibition shelf, the one that is always on the shelf.
Our factory are using software to calculate, or there is a formula about the form, the input value can be obtained as a result, in a, these things are going through finite element analysis and calculation and compressive shear experiment, and now is a rough estimate in the industry.
Shallow shelf steel structure is statically indeterminate structure, because part of the structure components exist large deformation, needs to add constraints through the statically indeterminate structure, and through the structure of the simplified method of statically determinate structure internal force calculation problem "lever" for every single group of internal force calculation problem.
Shelves column, beams, supporting components such as the section geometry size of width, sheet thickness (recruitment) is a lot smaller than its length, such as: the section size of pillar of shallow shelf is 30 * 30 ~ 150 mm * 120 mm, the node length between 300 mm to 1200 mm, and the basic proportion in more than 10 times; The length of the support is larger and sometimes 100 times greater, so the components of the shelf structure can be simplified.
