Structural Strengthening for Bridges

Although there are many ways to strengthen the bridge and improve the bearing capacity of the bridge, the basic principles are all the same, and all of them follow the basic principle of mechanics. From the angle of external factors and internal conditions of bridge structure to strengthening for improving the bearing capacity.

Main reasons of cracking in the concrete members

According to the investigation data, the cause of structure cracking in engineering practice is about 80% of the cracks caused by "deformation" or cracks caused by "deformation" as the main factor, and about 20% of the cracks caused by the "load" factors.

The characteristics of structural strengthening

Structural strengthening is to reinforce the original stressed structure, so as to meet the new requirements and safety, and save costs and reduce investment.

How to bonding CFRP on columns for seismic strengthening?

The use of externally bonded CFRP reinforcement method can significantly improve the seismic performance of columns, so that columns can have better inelastic deformation before the above failure occurs.

A solution for load increase

At present, there are many common reinforcement methods, such as enlarging section method, wrapping steel reinforcement method, sticking steel plate reinforcement method, carbon fiber retrofitting method and so on.

Improve aseismic performance of the brick concrete structure

The aseismic performance of the brick concrete structure is generally poor, its cross wall space is too large, it is not satisfied with the requirements of the standard, the bearing capacity is insufficient, the width of the house is not satisfied, the length of the window wall is not enough, and so on.

Strengthening for Reinforced Concrete Frame Structure

Frame structure is a common structural form of construction. With the increase of service life or the influence of external factors, the strength of the whole structure may be reduced, and it is urgently needed to be strengthened.

Rehabilitation and strengthening of buildings structures

The strengthening of buildings structures can be seen from two levels: 1. maintenance reinforcement due to damaged. 2. strengthen the building to achieve a certain degree of anti destructive ability, such as seismic retrofitting.

Reinforcement and repairing of bridge with steel plate

Sticking steel plate reinforcement can seal the cracks and defects of the bonding parts, restrain the deformation of concrete, and effectively improve the stiffness and crack resistance of the strengthened components.

Bridge strengthening with prestressed CFRP plate

The prestressed CFRP plate reinforcement technology reduces the normal peel force between carbon fiber and concrete components, improves the bond stress distribution, and effectively inhibits bond failure.
