The design of heavy-duty shelves should revolve around three core parameters: cargo weight, equipment parameters, and spatial conditions, and ensure structural safety through scientific calculations. Firstly, the single-layer design load-bearing capacity of the shelf should be determined based on the maximum weight of the goods, and a safety factor of 1.5 times should be reserved (if the goods weigh 10000kg and the design load-bearing capacity is ≥ 15000kg) to prevent sudden overweight; Secondly, based on the maximum lifting height and fork spacing of the access equipment, the total height of the shelf and the length of the crossbeam are determined. For example, if the lifting height of a heavy-duty forklift is 8 meters, the total height of the shelf is set to 7.5 meters, with a reserved operating space of 0.5 meters; Furthermore, based on the load-bearing capacity and flatness of the warehouse floor, the support area at the bottom of the columns is calculated. When the ground load-bearing capacity is insufficient, the support base needs to be increased to disperse the pressure. The calculation logic should follow the "Design Standard for Steel Structures" (GB 50017), calculate the bending strength of columns and the shear capacity of beams through mechanical formulas, ensure that the stress of each component is within a safe range, and consider external factors such as earthquakes and wind. In areas with frequent earthquakes, seismic accessories should be added to enhance the overall disaster resistance of the shelves.
