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.

Bridge strengthening-unidirectional carbon fiber fabric
CFRP fabric to bridge reinforcement is mainly embodied in the following aspects: the reinforcement of bending moment and normal section bearing capacity of shear members; the reinforcement of oblique section bearing capacity; the reinforcement of shear section; the reinforcement of compressive members and so on.

Reinforced concrete beams strengthened with CFRP system
There are many researches on the normal section, oblique section bearing capacity, bearing capacity and ductility of the flexural members strengthened by CFRP, and the design and calculation methods can be more mature. However, the above calculation methods are based on the CFRP cloth and concrete bond firmly, CFRP cloth strain reached the allowable strain before peeling failure.

CFRP reinforced concrete structures
Carbon fiber reinforced polymer ( CFRP) sheets reinforcement is a new type of method of structural reinforcement，which be- longs to the method of FRP composite strengthening system. In recent years, CFRP with light weight，high strength and anti － corrosion had been widely used in strengthening the reinforced concrete structure

Active reinforcement-Prestressed FRP laminate
The appearance of prestressed FRP laminate makes the structure reinforcement change from passive reinforcement with lagging force to active reinforcement. With the expansion of the application of prestressed FRP laminate, more and more projects have been affirmed.

Carbon fiber reinforced beam and slab structure
Carbon fiber fabric is suitable for reinforcement and repair of various structural types and parts, such as beams, slabs, columns, roof trusses, piers, bridges, cylinders, shells and other structures. The strength grade of base concrete is not less than C15, and CFRP fabric has been successfully used in various beam and slab reinforcement and maintenance in China.
