On the 8th of this month, an earthquake of magnitude 7.0 occurred in Jiuzhaigou County, Aba Prefecture, Sichuan Province. It has been for two weeks from the earthquake. The relief work is carried out in an orderly manner. The top priority is the restoration and reinforcement of the buildings. At present, the existing buildings in the Aba area have experienced different large and small aftershocks. The buildings themselves have been seriously damaged and even there are many cracks. So Mankate that is the Nanjing building reinforcement expert proposed that the purpose of doing the seismic reinforcement for the existing building was to let the existing building achieve the basic requirements of seismic reinforcement. That is, when the earthquake happens, the building structure can not collapse and hurt people. Let's take a look at how the seismic reinforcement expert says.
After the earthquake, the identification department will conduct a seismic identification for the building. And then according to the results, they do seismic reinforcement design for the buildings. Generally speaking, the traditional seismic reinforcement methods include increasing cross-section reinforcement, steel reinforcement and winding steel wire reinforcement. But today Mankate will talk to you about carbon fiber cloth reinforcement.
Carbon fiber cloth reinforcement method is a new method of reinforcement in recent years. But it is much important in the seismic reinforcement. In the building the real load-bearing is the pillars. So when reinforcing, we will use carbon fiber cloth ring beam reinforcement method for the pillars. We impose a ring constraint to the concrete column in order to improve the axes bearing capacity of concrete and ductility of the concrete column to achieve the purpose of seismic reinforcement. But we must keep to the following principles:
1)After conducting the building seismic identification, we should determine the suitable reinforcement method for the buildings. Don’t construct directly just by experience. After all, human life is the most precious;
2)The rationality of the load transmission. We should try our best to maintain the rational transmission of power of the original structure, eliminate or reduce the defects of the transmission of power of the original structure;
3)Because the buildings themselves are seriously damaged. During the construction, we must be sure not to cause the second damage to the structures of buildings. So now, carbon fiber cloth reinforcement is the strengthening method of the least loss for the buildings. It is recommended being widely used in the disaster area.
Above is the seismic reinforcement method that Mankate experts share. If you are interested in the Mankate carbon fiber cloth reinforcement, please call 400-894-5118.
