What is the skin effect? ​​Generally, the skin effect refers to the strengthening and management of the overall horizontal rigidity of the building by covering materials (roof and wall panels) on the surface of a building by using their own stiffness and strength. It is a ribbed and thin shell structure formed by covering the longitudinal and transverse ribs with metal material sheets. The skin and the rib jointly manage the work. The skin and its own enterprises have great influence on the tensile, compressive and shear damage in the plane. strength, and due to the ribbing, the skin does not buck. The development of the skin structure has a great influence on improving the bearing capacity and stiffness, while the self-weight is very light. The structural design concept of how to reflect the skin effect of the light steel structure and the technical effect of the skin is mainly from the Chinese aircraft and ship company industry. Plates, etc.) are covered to form a layer of skin, and the resulting mechanical teaching effect is called skin effect. The mechanical effect of the skin effect is carried out from three aspects: 1. In the case of only the skeleton; 2. In the case of adding diagonal braces inside the skeleton; 3. In the case of a skeleton and a support, OSB is used for skinning It refers to covering the skeleton with a specific structural board (OSB board, calcium silicate board, etc.) to form a layer of skin, and the resulting mechanical teaching effect is called the skin technology effect. Through the comparison of three different physical models, the mechanical effect of the skin effect under the same conditions with different properties can be experienced. 1: In the case of only skeleton 2: In the case of adding diagonal bracing inside the skeleton 3: In the case of network skeleton and diagonal bracing, OSB board is used for different skins of light steel houses. The skin effect is used to make the light steel The keel frame only covers the OSB board, and the lateral force transmission is used to increase the overall force degree and make the house more solid and stable. The role of skin effect 1) The roof panel in the portal frame is designed for the enterprise to resist the horizontal load from the gable wind-resistant column, transmit its information to the cornice, and then use the wall skin structure effect or The support passes to the foundation. 2) The gable wall in the portal rigid frame can be designed as a gable frame by using the shear skin effect of the wall panel, and there is no support between the columns (except for the large opening area of ​​the wall). 3) Under the influence of the vertical structure gravity, the roof purlins will produce side bending and torsion deformation. The plate connected to the purlin will eliminate this deformation, and the skinning technology effect of the panel can transmit its design shear force. To the connection between the purlin and the roof beam, and then transmit it to the roof construction beam in various countries through the purlin and the roof beam connector. 4) The plane of the upper flange plate of the purlin has sufficient rigidity to form a lateral constraint, which reduces the stable calculation length of the purlin and greatly improves the stable bearing capacity of the purlin. 5) The roof skin makes each plane rigid frame connect into an overall development space organization structure, and reduces the lateral movement of the rigid frame. When the cornice is high, the calculation of the control structure through the lateral displacement of the column top can bring economic benefits.
