Steel structure engineering: the core force of modern construction, helping the construction of large projects

Steel structure engineering is a structure mainly made of steel, consisting of steel beams, columns, Trusses, and other components made of steel sections and plates.

The components or parts are usually connected by welds, bolts, or rivets, and are one of the main types of building structures. Due to its light weight and easy construction, it is widely used in large factories, bridges, venues, super high-rise buildings and other fields.

Characteristics of steel structure:
1. steel Structures have a relatively light self weight
2. The reliability of steel structure work is relatively high
3. Steel has good resistance to vibration and impact
4. The industrialization level of steel structure manufacturing is relatively high
5. Steel structures can be accurately and quickly assembled
6. Steel structure with large indoor space
7. Easy to make into a sealed structure
8. Steel structures are prone to corrosion
9. Poor fire resistance of steel structure

Advantages of steel structure:

Seismic resistance: The roofs of low rise villas are mostly sloping roofs, so the roof structure is basically a triangular roof truss system made of cold-formed steel components. After sealing the structural panels and gypsum boards, the light steel components form a very strong "plate rib structure system", which has stronger seismic resistance and resistance to horizontal loads, and is suitable for areas with seismic intensity above 8 degrees.
Wind resistance: Steel structure buildings have light weight, high strength, good overall rigidity, and strong deformation resistance. The self weight of a building is only one-fifth of that of a brick and concrete structure, and it can withstand a hurricane of 70 meters per second, effectively protecting life and property.

Durability: The light steel residential structure is entirely composed of cold-formed thin-walled steel components, and the steel frame is made of super anti-corrosion high-strength cold-rolled galvanized sheet, effectively avoiding the influence of steel plate corrosion during construction and use, and increasing the service life of light steel components. The structural lifespan can reach 100 years.
Thermal insulation: The insulation material used is mainly fiberglass cotton, which has good thermal insulation effect. The insulation board used for exterior walls effectively avoids the "cold bridge" phenomenon of the wall and achieves better insulation effect. The thermal resistance value of R15 insulation cotton with a thickness of about 100mm can be equivalent to a brick wall with a thickness of 1m.
Soundproofing: Soundproofing effect is an important indicator for evaluating residential properties. The windows installed in the light steel system are made of insulated glass, which has good sound insulation effect and can achieve sound insulation of over 40 decibels; The wall composed of light steel keel and insulation material gypsum board can achieve a sound insulation effect of up to 60 decibels.
Health: Dry construction reduces the pollution caused by waste to the environment. The steel structure materials of the house can be 100% recycled, and most of the other supporting materials can also be recycled, which is in line with current environmental awareness; All materials are green building materials that meet the requirements of the ecological environment and are beneficial to health.
Comfort: The light steel wall adopts an efficient and energy-saving system, with breathing function and the ability to adjust indoor air dryness and humidity; The roof has ventilation function, which can create a flowing air space above the interior of the roof, ensuring the ventilation and heat dissipation needs inside the roof.
Quick: All construction work is done without being affected by environmental seasons. A building of about 300 square meters can complete the entire process from foundation to decoration in just 5 workers and 30 working days.
Environmental Protection: Materials can be 100% recycled, truly achieving green and pollution-free.
Energy saving: All use high-efficiency energy-saving walls with good insulation, heat insulation, and sound insulation effects, which can reach 50% energy-saving standards.

In the construction of building projects, the use of steel structure engineering for design not only enables the building project to have a larger span space, but also has the advantages of convenient installation and lower cost, making its application in building engineering increasingly widespread. With the further development of urbanization in our country, the number of high-rise buildings will sharply increase, which puts higher demands on the design of steel structure engineering.
In recent years, the application of steel structures in construction engineering has become increasingly widespread and has achieved very good results. However, in practical applications, there are also problems with insufficient stability of steel structure buildings due to inadequate design work in steel structure engineering, which seriously affects the safety of users' lives and property. In order to ensure the construction of steel structure engineering with higher quality, it is necessary to strictly follow the corresponding specifications and standards in the design of steel structure engineering, and do a good job in the corresponding design points, so as to provide users with safer and more reliable steel structure buildings.
