• Plastic rotation limit value for limited damage (SH) performance levels is calculated automatically according to Equation 5.7 and Equation 5.8 .

θ p (SH) = Allowable plastic rotation limit for Limited Damage performance level [rad]


According to Article 5.8.1.4 of TBDY , it is not allowed to form plastic joints in the carrier system for the Limited Damage (SH) performance level in new buildings . Therefore, for the Limited Damage (SH) performance level of plastic hinges , the plastic rotation limit value θ p (SH) must be zero.

In this case, the structure only makes elastic deformations. However, since the ŞGDT approach is applied, the effective section stiffness should be as specified in 5.4.5.2 TBDY (Effective Section Stiffness of Structural System Elements
