On 6 July, an earthquake occurred at 16:30 local time in the island of Leite, causing at least one person to die.
According to previously reported that the earthquake led to a collapse of the building in Kananga, many people were buried in the ruins. The Mayor of the city revealed that workers have rescued six people, but at least five people buried under the ruins. In addition found a victims.
Before the earthquake, we should do a good job of housing seismic reinforcement .For unqualified buildings,it’s nessary to strengthening and retrofiting .The following is the the seismic strengthening methods and components of seismic strengthening methods.
1.CFRP reinforcement method
Paste CFRP reinforcement method is to use high strength and high elastic modulus fiber composite material (carbon fiber cloth or carbon fiber board), with special configuration of the carbon fiber glue paste in bridge concrete component surface, with the strengthening methods of the original components to form the whole common force.
2.Steel reinforcement method
Outside sticking steel plate reinforced method is a kind of using hummer glued steel glue paste in concrete component surface, the steel plate directly to that of the component forming force as a whole, in order to improve the bearing capacity, increase the ductility, the reinforcement method of stiffness and meet the requirements of normal use.
