What environmental factors need to be considered when calculating the load-bearing capacity of steel structure platforms? 1. Temperature and humidity conditions: High temperature environments (such as workshops and boiler rooms) can reduce the strength of steel, and high-temperature resistant steel should be selected and the allowable stress adjusted; High humidity/damp environments (such as warehouses and underground spaces) can easily cause steel corrosion. When calculating, it is necessary to consider the loss of sections caused by corrosion, or to offset the impact through anti-corrosion treatment (galvanizing, painting) to avoid a decrease in load-bearing capacity. 2. Corrosive environment: Chemical and food processing scenarios may contain acidic and alkaline gases/liquids, which can accelerate steel corrosion. Therefore, corrosion-resistant steel (such as stainless steel) should be selected, or a larger safety factor should be reserved in the calculation to compensate for the structural strength loss caused by corrosion. 3. Vibration and impact: If there are forklift operations or equipment running on the upper level of the platform, vibration loads should be considered (usually 1.2-1.5 times the static load); Frequent loading and unloading of goods can cause impact, so it is necessary to strengthen the connection of components (such as using reinforced welds) during calculation to avoid local stress concentration leading to fracture. 4. Geological and ground conditions: Soft or uneven ground settlement can affect the stability of column support. When calculating, it is necessary to first evaluate the ground bearing capacity, and if necessary, improve the foundation bearing capacity through concrete reinforcement, adding embedded parts, etc., to prevent the platform from tilting due to ground deformation.
