After the earthquake disaster in Türkiye, 11 provinces were damaged. Although thousands of buildings were destroyed, the surviving buildings attracted people's attention.

It has been determined that the "carbon fiber" method is applied to some aseismic buildings.

It has been announced that the carbon fiber reinforcement system will be implemented in Istanbul, which is vulnerable to earthquake.

Ekrem, Mayor of Istanbul İ mamo ğ Lu drew attention to the earthquake preparation and talked about the carbon fiber system.

İ mamo ğ Lu said: "25 years have been wasted in urban reconstruction. Even if it continues at this speed, it can only be completed in 100 years. That is why we urgently switch to carbon fiber protection system to avoid losing the buildings that our people will surely collapse in the possible earthquake in Istanbul."

Imamoglu said that the reinforcement fee would be paid by the municipal government. In this way, we will reduce the risk of death.

The Turks accelerated their research on "carbon fiber". What is carbon fiber and what is its function? What is carbon polymer reinforcement? What is the price of carbon fiber?

However,

There is no so-called "I wrapped carbon fiber, and the building provides enough security". This is a structural and seismic engineering work. First, you should check the building and determine which application and how much.

We must be very careful. We should look for companies with structural and seismic engineers in the team and find them. These companies have reference materials, just as they decide which doctor to see. If carbon fiber is used indiscriminately, it may even damage buildings. We must obtain professional engineering services, just as patients should listen to doctors. This is like a doctor prescribing a prescription, first checking, determining the treatment method, and then applying the medicine to the case. Professional companies working in the field of construction and earthquake can do this.

Next, we will introduce the detection and identification, reinforcement design and reinforcement construction of the structural reinforcement project.

1. Structural safety inspection and appraisal

Structural safety detection and identification is the first step of structural reinforcement, and also one of the important bases for structural reinforcement and reconstruction. Whether the concrete structure needs reinforcement should be confirmed through structural reliability identification.

2. Structural reinforcement design

The reinforcement design is the most complex part of the structural reinforcement. The reinforcement effect of the structure is not only closely related to the adopted method, but also closely related to the state of the original structure. Although strengthening the local part of the structure can improve the mechanical performance of the part, it does not mean that the whole structure will be safer. The safety after reinforcement also depends on whether the original structural scheme and layout are reasonable, and whether the structural measures are appropriate. On the other hand, when carrying out the structural reinforcement design, attention should be paid to the structural connection and cooperative work, and the construction feasibility should be considered in the design, and the construction precautions and construction sequence should be put forward. Therefore, when carrying out reinforcement design, professional personnel are required to control and comprehensively consider the structure as a whole, and have higher requirements for the professional quality of designers.

3. Structural reinforcement construction

Compared with the construction of new structures, the construction of structural reinforcement is obviously easier. Many new methods in structural reinforcement do not need large machinery and wet operation, so the construction efficiency is much higher. However, simplicity does not mean that the requirements can be reduced. There are still many points to be paid attention to in structural reinforcement, for example, incomplete surface treatment of base material will cause complete failure of reinforcement. The construction must be carried out in strict accordance with the specifications to ensure the quality and effect of the reinforcement project. From the above structural reinforcement process, we can see that the complexity of structural reinforcement depends on the size of the strengthened structure. When the structure is strengthened as a whole, the uncertainties faced will increase exponentially. It requires the personnel involved to have strong structural theory and rich engineering experience to ensure the smooth progress of structural reinforcement, which is also one of the reasons why structural reinforcement will be considered complex.
