The steel structure design must follow the seven principles

Steel structure design
1, the construction of steel gutter ditch design should first meet the production process, building functions and types of requirements, and on this basis to be reasonable structure, safe and reliable, economical and economical. To this end, the structural designer should be fully aware of the production process and the construction function and art requirements in order to and process and construction staff to agree on the most reasonable program.
2, steel structure design, steel construction from the actual construction, taking into account the material supply and construction conditions, the rational selection of materials to meet the structure in the transport, installation and use of the process of strength and stability and stiffness requirements, but also to meet Fire prevention standards, attention to the structure of the anti-corrosion requirements. In the technical and economic indicators, should be for the conservation of materials, improve the production of labor productivity, reduce transportation costs and reduce the installation workload to shorten the construction period and other major factors, through multi-program comparison, according to specific conditions to seize the main contradiction to form Comprehensive economic indicators of the best program.
3, in the selection and determine the structural form and component cross-section, it should also improve the comprehensive squeeze benefits, not due to the gains and losses of a certain component of the overall economic indicators, such as:
1) The upper structure should be considered in conjunction with the foundation construction costs;
2) the roof of the building roof and the wall structure of the cost of a unified consideration;
3) There is a high degree of cross-section of the column and the construction area of ​​the plant.

4, in the possible conditions, and gradually to the structural shape, component and connection joints in the direction of standardization.
5, follow the principle of centralized use of materials, that is, the appropriate expansion of the column from the load-bearing structure of large-scale, reduce the number of components, the steel used to bear the main street structure.
6, in ensuring the safety and reliability of the structure under the premise of the implementation of the principle of functional merger, that is, a component can simultaneously assume a variety of functions, such as both from the load and the role of enclosure structure or both load-bearing components and stability of the grid Wait.
7, in the selection of steel should consider the structure of the working conditions, (such as force, temperature and surrounding media environment, etc.) material supply and processing of various factors. On all types of steel should be fully developed their role, so that each have their own. Make the best use of it. In a single component, two different steel grades are allowed. In the use of new materials, the focus is to promote the use of high-performance steel.
