Reinforced Concrete Chimney

Through calculation and analysis on routine examination and neutralization of reinforced concrete chimney, the service life of concrete structure was evaluated only considering neutralization of concrete single factor. The results show that the neutralization of the reinforced concrete chimney was serious than that of other similar projects. The initiation time of reinforcement corrosion were 19.3a, cracking time of concrete cover were 27.35a.

This paper introduced a project of reinforced concrete chimney with a height of 90 meters, which does not stop construction at nearly 200 degree Celsius, increased the height of the chimney with 10 meters. Reasonable structural measures were promoted to ensure the normal pouring of concrete chimneys. Compared with the normal condition, this measure is economical, low investment, feasible, etc. It provides far-reaching significance that increasing the height of the reinforced concrete chimney at the high temperature state.

Physical Laws

In the paper there is presented the algorithm of calculation of normal stresses in reinforced concrete three-flue chimney. The calculation has been made for full cross-section and for cross-section weakened by openings. The governing equations has been derived in an analytical form assuming linear physical laws for concrete and steel and, as for as considered cross-section weakened by openings, taking into account the additional reinforcing steel bars at the openings. In addition coefficients B and C have been determined, which are useful at dimensioning.
