Abstract. In recent years, with the improvement of science and technology level in China,
construction technology in the construction industry is constantly improving.In the traditional
civil engineering construction, the construction is through the concrete frame structure. Facing
the rapid pace of urbanization construction, various new steel structures are applied to modern
construction. Although steel structure technology has many advantages, there are still many
shortcomings in the application, need improving. This paper discusses the steel structure
technology in civil engineering construction.
1.Introduction
At present, China's infrastructure construction has achieved rapid development, especially in the
process of urbanization. All kinds of high-rise buildings continue to rise, making a great contribution
to the national economy and people's livelihood. The entire "life cycle" of the structure can be divided
into three stages: construction, use and aging. As can be seen from the figure 1, the average risk rate of
the construction stage and the aging stage is higher. However, on the whole, the construction
technology involved in the construction process of engineering construction in China is still in the
stage of development to some extent. Compared with foreign developed countries, There's still some
lag, especially in the application and promotion process of steel structure technology, that is
particularly significant. Steel structure technology plays an important role in high - rise buildings
especially super - high - rise buildings[1].

2.Steel structure characteristics
2.1Good performance
The steel structure is composed of manganese, iron and other elements, so it has diversified
characteristics, with good bearing capacity, hardness and shock resistance[2]. Compared with other
materials, it has good toughness and ductility. With the continuous development of science and
technology, the steel structure production level has a great demand. At present, the combination of
steel structure categories, the production of steel to meet the engineering categories, such as heat
resistant steel, high strength steel, stainless steel layer. This not only improves the construction quality
and efficiencybut also reflects the advantages of steel structure[3].
2.2be flexible
The plasticity of steel structure shows that its prestress is large and plastic deformation can occur to
some extent after exceeding the yield point to prevent structural fracture. This is a characteristic that
other materials do not have in the application process. In the process of using steel structure, it is
necessary to analyze the elongation and section shrinkage of a steel structure under the action of stress,
to determine its specific plasticity. The reason for its strong plasticity is that there are more carbon
elements in the steel structure, which can effectively improve the toughness of the steel[4]. In the
process of utilizing the steel structure, there is no need to worry about the stress exceeding the
tolerable range of the material. Technicians can adjust the shape of a steel structure according to the
design requirements, which can not only improve the construction quality of civil engineeringbut also
ensure its beauty.
2.3High environmental performance
High environmental performance is another prerequisite for utilizing steel structure technology in civil
engineering construction. The environmental performance of concrete buildings is relatively low. For
example, some used concrete buildings cannot be used again and can only be disposed of as
construction waste. Besides, due to the lack of garbage treatment technology, concrete waste cannot be
disposed of reasonably and can only be disposed of in uninhabited areas. However, the materials and
materials needed for steel structure technology can be used twice, effectively avoiding the generation
of construction waste and providing an effective basic guarantee for the ecological environment.
3.Application of steel structure in civil engineering
3.1 Reasonable selection of materials
In the process of selecting construction materials for steel structure, construction personnel needs to
investigate the actual situation of the steel market and analyze the application of profiles, plates, tubes
and metal products. For civil engineering construction, construction personnel needs to use low alloy
steel and carbon steel materials as the main steel to ensure their role in construction. In the case of
civil engineering construction in the past, although the hardness and strength of carbon steel are
relatively large, its plasticity is relatively poor in the application of carbon steel, which cannot
guarantee the improvement of construction quality. The steel structure cylinder used in civil
engineering construction is mainly an i-shaped section and a box-shaped section. For some projects
with special requirements, the section can be treated to make it a composite section. In the process of
choosing steel, the contents of these aspects need to be taken into comprehensive consideration.
Besisdes, the research of the welding process needs to be done to clarify the parameters of steel
structure and improve the application of steel structure technology.
3.2 Hoisting technology
In civil engineering construction based on a steel structure, hoisting, as a key step, determines the
construction quality of construction projects. The scientific use of hoisting technology can give full

play to the value of steel structure in civil engineering. It is also the impact of these factors, before the
construction, must do a good job of engineering analysis, clear engineering structure characteristics,
and then combined with the actual demand, scientific use of hoisting technology, under the condition
of ensuring the construction quality, improve the construction efficiency, let the benefit achieve the
best.
3.3 Apply the paint
After the application of steel structures, surface corrosion usually occurs, mainly due to the chemical
reaction between the steel surface and the air, resulting in corrosion. In this case, the performance of
the steel structure will change, resulting in its failure to support the overall structure and loss of
stability. The construction personnel can daub paint on the surface of steel structure, which needs to
pay attention to the daub technique of paint. Before daubing, it is necessary to do the basic treatment
of the steel structure, clean the metal surface, and carry out the derusting work.After brushing and
grinding the surface of the steel structure repeatedly, it is also necessary to polish it with a sand cloth
and clear the rust powder. Part of civil engineering construction needs to use a larger area of steel,
construction personnel can use a grinder to carry out the work of derusting.
3.4 welding technique
When steel structure technology is used in civil engineering, the material connection seems to be made
by means of welding. As the foundation of improving the application technology of civil engineering
steel structure, it has significant advantages in application to ensure welding quality. Although civil
engineering requires high quality and large quantity, the construction period is short, so there are high
requirements for welding. At present, there are many welding applications: butt welds, butt joints,
fillet welds, t-joints, spot welds and lap joints.In the application, it is necessary to integrate the
practical requirements, and select the appropriate way to improve the welding quality and efficiency,
to ensure construction quality and progress.
4. To improve the application strategy of steel structure construction technology in civil
engineering
4.1 Design reasonably according to site construction conditions
At present, China's civil engineering construction site and environment are relatively complex, and
there are many uncertain factors, which cause practical obstacles to the application of steel structure
technology. Therefore, based on the above situation, the author believes that, first, it is necessary to
carefully analyze the regional environment, climate factors and construction demand of the
construction site according to the actual environment and situation of the construction site, and
accurately grasp and understand the stress degree of the steel structure of the civil engineering. At the
same time, according to the maximum force standard of civil engineering hook machine, its negative
load value is calculated accurately. Secondly, the construction technicians should accurately predict
the possible deformation and subsidence in the civil engineering construction in advance, and then
make a careful comparison with relevant engineering data, to select a technical design scheme of steel
structure suitable for the civil engineering construction.
4.2 To lay the foundation of steel structure technology for civil engineering construction
At present, compared with the developed countries, the development of steel structure technology in
China is a little behind, the effective use of steel structure technology in civil engineering construction,
the need to master the basic technology, and advanced knowledge of steel structure technology. Such
as steel structure welding technology, tower technology, hoisting technology and other steel structure
technology. Do all the preparatory work to ensure that each process can be carried out safely. Welding
is affected by many factors, such as welding temperature, welding speed, etc., all affect the welding is
appropriate, master the welding technology is very important. Crane tower technology is very

important in civil engineering construction, the use of crane tower technology for the steel structure
construction of mechanical equipment to lift heavy objects, in the construction process of construction
personnel should be strictly by following the mechanical provisions of the construction, to ensure the
safety of personnel. Before construction, all projects should be checked clearly, construction personnel
understand the construction process should pay attention to the problem, there are solutions to
emergencies, do all the preparatory work before construction.
4.3 We will put in place a sound regulatory system
In practical work, we must establish a feasible, scientific and reasonable regulatory scheme. First of all,
the relevant system should meet the national laws and regulations, combine the requirements of the
complete regulations, let different departments work together, in the case of each person to perform
their duties, take the initiative to assume responsibility, to ensure the smooth completion of relevant
work. An effective supervision scheme can monitor the construction situation in real-time, prevent
safe construction, and carry out follow-up treatment based on the accident situation, to improve
economic benefits and reduce the accident rate.
5. Conclusion
At present, the development scale of the civil engineering industry in China is gradually expanding.
As an important link to civil engineering construction, steel structure technology is of relative
importance and influence. In the process of using steel structure construction technology to carry out
civil engineering construction, construction personnel needs to improve their ability and level, to
provide the foundation for the application of technology. The construction unit should choose the
material reasonably, let the steel structure give play to its excellent performance, reduce the problem
in the construction.
