How to calculate the load-bearing capacity of a steel structure platform? 1. Clarify the load parameters: First determine the total load, including static load (cargo, platform weight) and dynamic load (additional force from forklift/personnel operations, usually 1.2-1.5 times the static load), and calculate the unit area load according to the actual storage plan (such as 500kg/㎡). 2. Selection of core component specifications: Select the steel (I-beam/channel steel) model based on the unit load, refer to the mechanical parameters of the steel (such as the bending strength of Q235 steel), and calculate the bending and shear resistance of the component through formulas (for example, the beam needs to meet the bending moment ≤ section bending modulus × allowable stress). 3. Calculation of support and connection: Calculate the load-bearing capacity of the columns (total load ÷ number of columns, with a safety factor), check the strength of bolts/welds, and ensure that the load-bearing capacity of the connection points is not lower than that of the components themselves. 4. Verify overall stability: Based on the platform span and floor height, verify the structural resistance to lateral displacement and overturning through mechanical software or standard formulas, avoid local overload or overall instability, and ultimately ensure that the design load-bearing capacity is ≥ 1.2 times the actual total load safety factor.
