Study on residual carrying capacity of existing reinforced concrete poles

Reinforced concrete poles were exposed atmosphere,affected by entironment and inner stress,would be engendered aging phenomena that cracks and reinforcing steel bar rusting.The aging disease debased mechanical performance of reinforced concrete poles,thus influenced the safe and steady function of electric power system.The article made use of three reinforced concrete poles's test,opened out mechanical mechanism,breakage shape,residual carrying capacity etc.Predominating mechanical performance of reinforced concrete poles possess greatly realistic sense for the safe and steady function of electric power system.
