Seismic Performance of a Corroded Reinforce Concrete Frame Structure Using Pushover Method

Table 8

Bending strength of corroded beam hinge (M3) under different degrees of corrosion.

Corrosion rate (%)	Beam ①		Beam ②
	+M (kN·m)	−M (kN·m)	+M (kN·m)	−M (kN·m)
0.0	129.9	198.8	151.3	162.8
5.0	118.1	180.7	137.5	148.0
10.0	103.4	158.2	120.4	129.5
18.0	74.0	113.3	86.2	92.8

+M represents the bending strength of the bottom longitudinal reinforcement; −M represents the bending strength of the upper longitudinal reinforcement.
