Study on the Regularity of the Influence of Wind Pressure on the Properties of Concrete Carbonation

The distribution of surface pressure of columns in concrete bridge with the effect of wind load has been simulated by Ansys software. Carbonation model of concrete in windy environment has been established by analyzing the relationship between the wind pressure, carbonization time and carbonation depth. Furthermore, by Taking air pressure of concrete surface into the carbonation model, there is a good consistency between the test value and the measured value of the actual place. At last, the design method of the durability of concrete structures under wind loads, which is based on concrete durability limit state, has been putted forward to determine the expression of the breakdown coefficient.
