How to strengthen the steel structure bridge?

With the development of the construction industry, steel structure as one of the new building materials has been gradually applied to our life. Foshan steel structure can be used in buildings such as factories, large buildings, schools, villas and so on. Steel structure is also very good for the use of bridges. Steel structure bridges can be divided into many kinds of structural bridges, including slant legged rigid frame bridges, rigid frame bridges, T rigid frame bridges and continuous rigid frame bridges. The reinforcement methods of steel structure bridges are as follows:
1. the strengthening technology of bonded steel plate is used to reinforce the structure, and the load bearing capacity of the original structure is always strengthened by the combination of components and bonded steel plates.
2. the method of enlarging the section area can increase the bearing capacity and rigidity of the bridge.
3., the structural system can be changed to reinforce, reduce the internal force of key sections and increase the bearing capacity of the whole bridge.
4. or external force can be exerted by adding proper amount of external prestressing reinforcement to the main girder.
There are a lot of reinforcement methods for Foshan steel structure bridges. Different reinforcement methods are adopted for different structures. When strengthening, the most suitable method should be chosen to reinforce.
