This article first introduces the basic characteristics of multi story industrial steel structure factories from three aspects, then points out the shortcomings in the structural design of multi story industrial steel structure factories, and finally elaborates on the relevant key issues in the structural design of multi story industrial steel structure factories from multiple perspectives.
1. Basic characteristics of multi story industrial steel structure factory buildings
1.1 Strong load-bearing capacity of industrial plants
Under the development conditions of the new era, China’s industrial plants are also moving towards modernization. Unlike ordinary residential buildings, industrial plants store more large machinery and equipment, raw materials, etc., and these large equipment will cause certain vibration phenomena during operation. This requires industrial plants to have stronger load-bearing and compressive capabilities. Multi story steel structures are required to have better bearing capacity, usually with live loads ranging from 2.5 to 20KN per square meter, which is much higher than the general load of civil buildings. In actual construction, placing relevant machinery and equipment on reserved equipment platform supports can effectively improve construction efficiency and shorten the construction period.
1.2 Short construction period
Multi story industrial steel structure factories not only have strong load-bearing capacity, but also have a relatively short construction period. The equipment in multi story industrial steel structure factories is relatively large, so they require a lot of space and are generally used for production line work; The construction work mainly involves assembling steel structure frames, and there are fewer detailed constructions (such as decoration requirements) compared to general buildings, so the construction period is shorter.
1.3 Large suspension and concentrated load capacity
In industrial production, when operating various large-scale equipment, the vibration is relatively strong, and coupled with the weight of the mechanical equipment itself, the concentrated load also tests the stability and bearing capacity of multi-layer steel structures. In addition, the centralized placement of large equipment also generates some hanging loads, further increasing the difficulty of industrial plant design. For multi story industrial steel structure factories, it is more convenient to suspend concentrated loads and highlights the advantages of such industrial factory design.
2. Shortcomings in the Structural Design of Multi story Industrial Steel Structure Factory Buildings
2.1 The seismic resistance function of multi story industrial steel structure factory buildings needs to be enhanced
In response to the phenomenon of heavy loads on multi story industrial steel structure factories and the comprehensive consideration of preventive measures against natural disasters. The seismic performance of multi story steel structures still needs to be strengthened. When earthquakes occur around many industrial plants, problems such as building collapses, employee injuries, and equipment damage occur together. Especially in earthquake prone areas such as Sichuan, the seismic resistance of industrial plants should be scientifically evaluated to design the overall structure, ensuring that industrial plants can reduce damage caused by earthquakes and improve the safety factor of industrial plant operation.
2.2 Ensure that the structural design of the factory building is sufficiently safe and applicable
When designing multi story industrial steel structure factories, a high safety factor is the first criterion. Pursuing the optimal cost-effectiveness of factory design while ensuring construction safety and usage safety. Generally speaking, for the vast majority of production enterprises, maximizing economic benefits is their production and operation goal, improving production efficiency, and reducing cost inputs.
3. Key points and issues related to the structural design of multi story industrial steel structure factory buildings
3.1 Design to improve the seismic resistance of steel structures
At present, the number and scale of modern industrial plants in China are increasing. Therefore, if a safety accident occurs, it will bring serious threats of casualties and economic losses. Therefore, in the process of designing the steel structure of a multi story industrial steel structure plant, relevant designers and construction personnel must prioritize the safety of the industrial plant, ensuring that the technology for constructing multi story industrial steel structure plants meets the national standards and requirements. Among them, relevant departments should improve the composition of steel structures and their seismic resistance during construction to ensure the actual seismic performance of steel structures. In addition, during the construction process, it is necessary to strictly manage and control the construction materials to ensure that the quality of the materials meets the construction requirements, thereby better improving the overall seismic resistance of the factory building.
3.2 Key points of support system design
In the process of designing multi story industrial steel structure factory buildings, the design of the support system is a very important part of the design process. When designing the factory structure, relevant designers must strengthen their attention to the design of the support system. The design of the supporting system is also related to the safety of industrial plants. If not designed properly, it can also lead to serious safety accidents in industrial plants. When designing the support system, it is important to ensure that every operational step and process is carried out under normal conditions, rather than in an ideal state. Both subjective and objective factors can have a certain degree of impact on the design of multi story industrial steel structure factories. Based on the needs of industrial process flow, the continuity design of the supporting system should be considered in the early stage of the plan to guide the formulation of the building scheme.
3.3 Design points for node construction
In the process of designing multi story industrial steel structure factory buildings, attention should also be paid to the design of node structures. Due to the fact that the positions of nodes are not the same, the forces exerted on nodes at different locations are not the same. Therefore, designers need to have a holistic design concept, starting from the whole and then progressing to the parts, in order to carry out various design processes.
3.4 Calculation Issues in the Design Phase
In the process of designing a multi story industrial steel structure factory, it is also necessary to pay attention to the calculation issues at different stages. For example, the load capacity of industrial plants, the stability level of their structures, and the seismic performance indicators of steel structures all need to be accurately calculated with the help of computers in order to further strengthen the control of structural design.
