How to calculate the load of the grid steel structure? The main loads of the grid steel structure are divided into three types: active load, permanent load and variable load. Generally, the load is the self-weight including the reticulated structure, and the roof is maintained. The weight of the structure, the load on the suspension equipment and the load on the horse. For the storage bins, there are four main types of variable loads, namely roof load, snow load, wind load and ash load. How is the load of the grid steel structure calculated? Let us Let's learn it.
First, the ash load of the grid steel structure is a kind of load that must be considered in the construction and metallurgy industry. This is uniform throughout the country, about 0.5KN/m2 or LOKN/m2. However, if it is in the power plant or coal industry, the production environment of the grid steel structure of the coal storage plant inside is better, and the ash load can be ignored. At the same time, the snow load or the excessive load in the roof load should be considered together with the ash load.
Second, the snow load is also an important load of the grid steel structure. The snow load is a sensitive load for the structure of a large span. In many countries, the accident of the grid steel structure collapsed in heavy snow days occurred in a cold area with snow. It is necessary to consider the snow load, and should also consider the uniform distribution, uneven distribution and semi-uniform distribution of the roof.
Third, there are three main reasons that affect the distribution of snow load on the roof. The wind factor, roof shape and roof slope factor are generally controlled. The snow load that is unevenly distributed in the grid steel structure generally has a control effect. Loads generally need to be considered simultaneously with the ash load.
The above is the information on how the load of the grid steel structure is calculated.
