Basic principles of light steel structure design for industrial buildings

Light steel structures are increasingly used in industrial buildings for their low cost, high strength and quick installation. The design of such structures should take into account several factors, such as the size of the structure, the loads it will carry, the geometry of the structure, and the type of materials used.

The size of the structure should be determined by the use of the building and the available space. The size of the structure will determine the required strength and stiffness of the components in the structure. The loads that the structure will be subjected to must be determined to ensure that the structure can safely withstand these loads. This includes the weight of the building, wind loads, snow loads, and any other external loads. The geometry of the structure should be determined based on the use of the building. This includes the size, shape and orientation of the structure. The geometry will determine the type of connections that must be used in the structure.

The type of materials used in the structure should also be considered. Lightweight steel structures are usually made of lightweight steel that is strong and durable. However, depending on the use of the building, other materials such as aluminum and wood can also be used in light steel structures.

1、Principle of applicability

The nodes should be selected with applicability, which can be simulated with the help of computer equipment to check whether the design scheme meets the industrial building standards, and then judge the specific frame structure, and if problems are found, optimization is needed to ensure that the subsequent put into use can be safe and stable. At the same time, the design also needs to consider the needs of the industrial building during use, including equipment placement and personnel activities, and the need to consider the lighting performance, etc. After determining the form of the structure needs to be designed to check, if found that some areas of serious stress need to increase the strength of the material, combined with the actual reinforcement treatment, such as the structure is difficult to meet the needs of the need to change the form of the structural frame. Industrial buildings with large indoor space, light steel building frame should be reserved for enough vents and set ventilators at key locations; when considering indoor light intensity, heat insulation building materials can be used, analyze the antioxidant capacity of the materials applied subsequently, reduce the accumulation of heat during use and avoid the unsuitable situation.

2、Safety principle

In the design, according to the characteristics of industrial buildings, analyze the fire resistance level as well as the seismic level, multi(single)-story light steel structures all need to be designed for fire resistance and seismic resistance. The coating performance index must meet the “Technical Specification for the Application of Steel Structure Fireproof Coating”; while the seismic resistance needs to meet the “Code for Seismic Design of Buildings”. Light steel structure of industrial buildings through the larger scale, in addition to the internal office area will also be facilities office, warehouse, etc., the external will be set up auxiliary room, then the empty joints to take sealing measures, materials need to be combined with the actual choice, including insulation board, fire board, sealant, etc., to ensure the overall quality of industrial buildings.

3、Economic principles

In the design of industrial building light steel structure, also need to consider the economic principle, according to the characteristics of production and the requirements of the implementation of the enterprise, after the comparison of the program to arrive at the optimal program, which includes the project site, planning location, building materials, monomer size, building shape, etc., with the building, electricity, water, process, HVAC, try to use standard size products, in the premise of meeting the code requirements as far as possible to save money consumption. The design of the structure should also consider the cost of materials and the labor required to build the structure. By considering these factors, the design of light steel structures for industrial buildings can be optimized for cost, strength and construction speed.

4、Aesthetic principles

Industrial building projects also need to consider aesthetics in the design, requiring adequate and complete internal space, combined with the total height of the floor and the bearing capacity of the base, and the structural column distance can generally be set within the range of 8~9m. Industrial building shape is simple, uniform specifications, according to its own characteristics can be used less part of the decoration and internal decoration, exterior wall panels can choose fluorocarbon coating, high (low) wave pressure type color steel plate, small color steel, etc., combined with the actual consideration of light and shadow effect changes, so that the overall appearance effect is further improved.
