Numerical Analysis of the Degradation Characteristics of Bearing Capacity of a Corroded Reinforced Concrete Beam

Table 9

Comparison of parameter lower rate and corrosion rate.

Corrosion rate of cross section	Reduction percentage of yield load (%)	Reduction percentage of yield displacement (%)	Reduction percentage of ultimate load (%)
0%	0	0	0
5%	9.3	5.0	7.1
10%	21.2	10.0	23.0
15%	34.8	17.5	41.9

Note: reduction percentage = (no corrosion index − corrosion index)/no corrosion index × 100%.
