Study on the Deterioration Properties of Corroded Steel Based on Weibull Distribution

Article Preview

Abstract:

The change of steel mechanical properties is because of steel corrosion seriously. An important factor of evaluating the performance of active steel structure is the degradation of steel mechanics performance. Corroded steel mechanics performance degradation accords with four parameters Weibull distribution through analysis the rapid steel corrosion experiment data. The each Weibull distribution parameters of the degradation of the steel corrosion rate, yield strength and ultimate strength are solved through Matlab programming. Weibull distribution simulation results and experimental data agree well. These models can predict the degradation of steel mechanics performance and can help people to evaluate the corrosion steel structure bearing performance to reinforce the steel structure.
