The development status and prospect of steel structure building are briefly described

At present, steel structure buildings have been widely used in civil buildings and plant construction, and steel structure has shown a particularly important attitude in the construction field. Because the steel structure itself has the characteristics of convenient construction and stable performance, it is widely used in the construction industry, and is loved by users, with good application value and development prospects. In the current technical environment, exploring steel structure buildings, so that steel structure buildings can show their own role in economic construction, has become the focus of the construction industry. This paper analyzes the development status of steel structure building, thus discussing the development status of steel structure building, in order to discuss the prospect of steel structure building, and accelerate the rapid development of steel structure building.
1. Development status of steel structure buildings
1.1 Steel development status
The development of steel has become an important part of the development of steel structure buildings, in order to meet the needs of the construction market, finished steel will gradually move towards the direction of complete varieties and standardization of materials. The building steel structure has shown a rapid development momentum in terms of the quantity, variety and quality of steel, which provides an important environment for the development of steel structure buildings. The output of shaped steel and coated steel plates in other steel structures has increased significantly, and the quality of products has also been significantly improved, and corresponding new steel sections such as large fire-resistant, weather-resistant steel and ultra-thin hot-rolled H-shaped steel have been gradually used in the project, paving the way for the future of steel structure buildings.
1.2 Development status of steel structure design and construction methods
The specifications of steel structure design are continuously improved, which also provides an effective guarantee for the designers of China’s steel structure industry to improve their professional literacy, and various forms of steel structure design software suitable for the use of computer technology have been gradually developed. In recent years, great progress has been made in the construction technology of steel structure, such as lifting and sliding technology with large span, microcomputer hydraulic overall lifting technology with intelligent system, software simulation and simulation technology used in the construction and installation of steel structure, etc., problems existing in the construction plan can also be detected in advance and modified in time, eliminating the procedure of site trial assembly. It has achieved twice the result with half the effort.
The green steel structure building itself has a huge carrying capacity, which not only refers to the project itself, but also includes the carrying capacity of the ecological level, with light weight, rapid construction, good quality, low cost and other advantages, so as to meet the green building in saving land, saving water, saving electricity, saving consumables, saving energy environmental standards. In addition, it can save resources and low-carbon environmental protection in the entire use process of the building, complete the optimal allocation and recycling of resources, and become not only to ensure that resources will not be exhausted, but also to present a new type of building development situation of ecological protection. The steel structure building uses the industrialized, modern and standardized production form, which belongs to the resource-saving good building form, and can form the recycling type of building industrialization industrial system.
2. Application prospect of steel structure building

At present, although a large number of steel structures have emerged, but on the whole, steel structure buildings are still in the development period, and there are still many aspects that need to be developed. Steel structure buildings have good development prospects, mainly in:

2.1 The characteristics of the steel structure itself can better meet the needs of building development

The steel structure has the characteristics of light weight and high strength, so the steel structure can be applied to some buildings with large spans and heavy loads. This is because brick and concrete buildings do not have these advantages, so the use of steel structure in the construction can effectively reduce the construction time, minimize the construction cost, and improve the economic benefits of construction enterprises. The steel structure building has good earthquake resistance, which is because the stress amplitude of the steel structure has good toughness and elasticity, and will not break due to sudden increase in weight. For some earthquake-prone places such as Southeast Asia and Japan, steel structure has become the primary choice for construction, which has been highly recognized by local people, and has repeatedly reflected the minimum damage of steel structure buildings in earthquakes. Because the steel structure building in the rapid development stage, the current steel structure building has been in the standardized construction period, the quality of the steel structure is more stable, the construction technical requirements are low, and the labor intensity is also low, the construction personnel only need to strictly install bolts and welding during the construction can be completed, and the construction cycle is shortened at a larger level.

2.2 The rapidly developing economy has strong demand for steel structure buildings
Due to the rapid development of the economy, the rapid development of the real estate industry has been promoted, and more and more people want to buy commercial housing, which has significantly increased the speed of real estate construction. Large buildings not only require higher engineering quality, but also put forward higher standards for the utilization of building space, but traditional construction methods are more difficult to meet these standards.
Whether as a brick-concrete structure or a concrete structure, due to the construction time is too long, the structural span is limited, etc., it is usually difficult to meet the requirements of short construction period and large span, and the steel structure can just meet this standard. In view of the construction situation, almost all large venues are using the steel structure building system, some larger plants are also commonly used for the construction of steel structure, this height of the steel structure required, will be continued in a long period thereafter, so the steel structure also has a very good development prospects.
3 Conclusion
All in all, the current building more and more began to use large-span steel structure, large-span steel structure creation technology is also more mature, and due to the research and development of new materials and the use of new technology, large-span steel structure for economic, stability and even advanced aspects have long-term development, but there are still many design and technical problems to be solved. There are still many construction techniques that need to be explored in construction. It is hoped that through the analysis of the development status and prospect of steel structure building, it will guide the development direction of the construction industry.
