FRP strengthened frame structure under seismic loading
Using FRP material can effectively enhance the aseismic capacity of frame structure and obviously improve the deformation and failure caused by earthquake. The improvement of structural strength is closely related to reinforcement methods. The results show that the strength of the frame strengthened by N SM method is increased by about 20% compared with the E B method.

FRP composites in structural reinforcement
At present, the commonly used reinforcement methods in China are mainly FRP composite reinforcement, steel plate bonding, enlarged cross-section and other methods. From the above analysis, FRP composite reinforcement method has obvious advantages, and has good economic benefits, will be widely used in structural engineering.

FRP strengthening or steel plate reinforcement
In structural reinforcement, FRP composite strengthening and steel plate strengthening are two commonly used methods in concrete structures. In the selection of reinforcement schemes, the two methods often appear simultaneously. From the point of view of the mechanism of action, the two reinforcement methods are formed by structural adhesive and concrete base material as a whole, and the two methods are similar in construction technology, often causing certain obstacles to the choice of methods.

Why wrap carbon fiber fabric?
Carbon fiber wrapping, at present the main reason is "carbon fiber heat" or can be said to be "carbon fiber line heat", do not say how the performance of the first, simply coated words, mainly forced high. Secondly, the combination of carbon fiber fabric and resin has a certain strength and hardness, and has a certain significance of protection.

Problems of steel jacketing in concrete reinforcement
External bonding steel plate or steel jacketing reinforcement method is a kind of reinforcement method of wrapping steel around reinforced concrete beams and columns. Steel jacketing reinforcement method can greatly improve the bearing capacity of the original member on the basis of increasing the section size of few members.

Concrete column strengthening method with different stress
In fact, in addition to the different modes of stress, the selection of concrete column reinforcement scheme is related to multiple factors. The scheme selection should also take into account the specific characteristics, technical and economic conditions of the original structure.
