Views on the durability of steel structures

Research status at home and abroad:

Steel has many advantages such as high strength, small size, convenient manufacturing and installation, etc., and it is more and more widely used in building structures. However, due to the influence of natural environmental factors and the corrosion of harmful external media, the steel is prone to corrosion, which in turn causes the effective section of the component to be reduced and the bearing capacity is reduced. In addition, under repeated loads, fatigue damage will occur due to crack propagation and damage accumulation. Therefore, the durability of fabricated steel structures is a matter of great concern to the engineering community.

The current research on the durability of steel structures mainly focuses on:

1. The protective film destroys durability;

2. Atmospheric corrosion damage durability of the base metal section;

3. The durability of bearing capacity under the combined action of atmosphere and stress;

4. Four aspects including fatigue cumulative damage durability

Is the durability design of steel structures important?

1. With the increase of steel output and the maturity of steel structure design theory, the number and scale of steel structure projects in my country have increased year by year. However, the durability of steel structures is poor, and many large steel structures are exposed to corrosive environments such as marine atmosphere and industrial atmosphere for a long time. Projects such as bridges, television towers, high-voltage transmission towers, large reservoir gates, and offshore oil production facilities all have corrosion problems.

2. The anti-corrosion problem of steel structure has also received more and more attention in construction engineering. As a steel structure engineering design and construction personnel, if you want to improve the durability of building steel structures, you must have a considerable understanding of anti-corrosion. Therefore, how to improve the durability and quality of the steel structure in actual construction is very critical according to the information of comprehensive housing on the Internet.

Through the above, we have made a detailed explanation on the question of whether the durability design of steel structure is important. I believe everyone should see it clearly. By the way, we pay special attention to the characteristics of steel structure, so that we can be better. Use it.
