A cooling tower has been used for more than 20 years

and there is a certain degree of aging and damage.The appearance of the tower

the degree of carbonation of concrete

the degree of corrosion of steel bar

and the degree of inclination are detected.Using finite element method

the internal force and deformation of the cooling tower are calculated

when the wind load

temperature load and gravity load work respectively and simultaneously.The overall stability and local stability analysis

the crack development under the combined loads are carried out.The results show that the rigidity

strength

safety coefficient

overall stability and local stability coefficient of the cooling tower can meet the requirements of the specification.In addition to some area of the tower

the crack width of the other of the body is satisfied with the maximum crack width.According to the results of the test and finite element calculation

the strengthening measures of the cooling tower are as follows:sticking carbon fiber cloth

anti-carbonation treatment of concrete surface

derusting and antirust measures

etc.
