What is seismic strengthening of buildings? 

The earthquake resistance, that is, when an earthquake occurs, the seismic capacity of buildings is affected by the earthquake. Seismic strengthening of buildings refers to the fact that the original design of the buildings cannot meet the requirements of the seismic code, or the service life of the buildings is too long, and the seismic capacity is reduced, so the buildings need to be strengthened against earthquakes.

Is it necessary to strengthen the buildings against earthquakes?

Every day, we can see where the earthquake occurred, how many earthquakes occurred, how many houses collapsed and so on. Why do some houses collapse when an earthquake occurs, while others are undamaged? There is no doubt that the earthquake level has been reduced, or the buildings are aging and other factors.

What kind of buildings should be reinforced in time?

Some old buildings need to be strengthened against earthquakes, and some countries generally require buildings to conduct earthquake identification and investigation in areas prone to earthquakes. If the seismic identification results show that the seismic capacity is insufficient, seismic reinforcement must be carried out.

What are seismic strengthening measures?

Seismic strengthening measures are measures taken to enhance the strength, improve the ductility, strengthen the integrity and improve the force transmission way to make the existing construction project meet the specified seismic fortification requirements.

What are the commonly used seismic reinforcement technologies?

Anchoring reinforcement method, sticking steel method, carbon fiber strengthening method, enlarging section method, outsourcing steel method, fastening technology, etc. There are a variety of special seismic reinforcement technologies, which is applicable? This requires us to compare various reinforcement measures and select highly feasible seismic technology according to the actual seismic situation of buildings.

How to effectively improve the seismic grade of buildings?

We should not blindly deal with the seismic reinforcement of buildings. First, we should understand the current situation of the building structure and deal with it according to the actual situation. Although the seismic rating of some buildings does not meet the standard, the problem is not too serious and will not affect the normal use of the house temporarily. We cannot underestimate these buildings with insignificant or slight seismic performance. Otherwise, the house will not be able to conduct seismic treatment, and the seismic performance will only become lower and lower, and it is impossible to repair the house before construction.

Before construction: determine the current seismic grade of the house, purchase appropriate seismic building materials, and the seismic reinforcement company will also analyze which reinforcement measures are appropriate during the construction process.

During construction: carry out accurate operation according to the design feasible construction scheme, check and identify whether the quality of the anti-seismic works treated is qualified in real time, and rectify as soon as possible.

After completion: the daily maintenance of the house should not be underestimated, and it is also very important to conduct regular anti-seismic testing during use.
