While defining section damages , internal forces or deformations found by applying any of TBDY Section 15.5 linear calculation methods and Section 15.6 nonlinear calculation methods and earthquake calculation methods are compared with numerical values corresponding to section damage limits in 15.3.1and 15.3.2 . In this case, the Limit Damage (SH), Controlled Damage (KH) and Pre- Collapse Damage (LO) limit values of the plastic hinges are calculated and compared with the plastic rotation value. This process is done separately for all earthquake loading cases and the section damage zone is determined for the most unfavorable case.
