The development direction of steel structure mainly includes the following aspects
The research, development and application of high-strength steel products use high-strength and high-quality steel or other light metals, which is conducive to the production of high-efficiency steel structures and the construction of super-long-span structures, super-high-rise buildings and high-rise structures with fewer materials.
The application of new structural system, space structure or suspension structure system with high strength steel and new structural form is an important factor to improve the benefit of steel structure, so the innovation and application of structural form should be strengthened. The new structural types include thin-walled steel structure, suspension structure, suspension structure, grid structure and prestressing steel structure. These structural types should be applied in light-weight buildings, long-span roof structures and high-rise buildings.
The development of steel products and the application of new steel components are important directions for the development of steel structures. These new products include H-section steel, profiled steel sheet, color galvanized steel sheet, etc. Steel and concrete composite members are economical and reasonable composite structures, which should be widely used. At present, profiled steel sheet and concrete composite slab, steel-concrete composite beam, concrete filled steel tube column and other forms are being popularized and applied.
The application of new computing and testing techniques and advanced computing and testing techniques is of great significance to the correct and rational structural design and the determination of the actual working state of the structure. It is also an important means to study the calculation methods and structural theory of the improved structure, so it should be strengthened.
