Abstract
Corrosion of steel reinforcement bars is a common problem for high-pile wharf in service, with the aim of solving this problem, a method to calculate the actual bearing capacity of corroded beam-slabs is proposed, in which the rate of loss of area and the reduction in strength of steel bars due to corrosion are considered. Taking Zhanjiang Port as an example, the actual bearing capacity of corroded beam slabs is calculated and is compared with that found under normal service conditions. For repair of corroded beam-slabs, a method in which fiber-reinforced polymer (FRP) bars partly replace the steel bars is proposed, and the basic assumptions and method of calculation for this mixed-reinforcement components are discussed.
