The main reinforcement methods of civil buildings?

There are a variety of ways to reinforce building, but mainly from two aspects, one is retrofitting to the damaged and the other is up to a certain resistance to abuse such as seismic retrofitting

First, the foundation reinforcement:

(1) Reinforcement of foundation by grouting: It is applicable to reinforce foundation on the basis of uneven settlement due to stress, frost heaving or other reasons.

(2) To increase the basis of the bottom area: It is applicable to reinforce existing buildings when the foundation bearing capacity or foundation area size does not meet the design requirements.

(3) Anchor Static Pressure Pile: It is suitable for foundation soil consolidation and rectification and consolidation of silt, muddy soil, cohesive soil, silt and artificial soil.

(4) Root reinforcement: It is suitable for foundation soil consolidation and rectification and consolidation of silt, muddy soil, cohesive soil, silt and artificial soil.

Second, the column strengthening:

(1) Reinforcement of concrete enclosure: It is suitable for reinforcement when the cross-section flexural capacity and shear capacity are not enough.

(2) Epoxy bonded steel plate: applies to the serious lack of capacity when the cross-section, and does not allow to increase the cross-section reinforcement.

Third, the wall reinforcement:

(1) Mortar surface reinforcement: suitable for carrying capacity of similar static reinforcement and seismic reinforcement.

(2) Reinforced mesh mortar surface reinforcement: suitable for static reinforcement and high strength seismic reinforcement.

(3) Reinforcement of reinforced concrete wall: apply to a larger increase of static reinforcement and seismic reinforcement.

Fourth, the beam strengthening:

(1) Steel jacketing, epoxy bonded steel plate reinforcement.

(2) The use of carbon fiber fabric, carbon fiber reinforced polymer laminate(CFRP laminate/strip/plate).

(3) The use of increased cross-section reinforcement.

Fifth, the slab reinforcement:

(1) Steel jacketing, epoxy bonded steel plate reinforcement.

(2) The use of carbon fiber fabric, carbon fiber reinforced polymer laminate(CFRP laminate/strip/plate).

Six, the balcony strengthening:
