Deformation based damage limits of conventional reinforced concrete coupling beams were analytically investigated considering the Turkish Seismic Building Code 2018 (TSC, 2018). Moment-curvature values of the conventional reinforced concrete beams were calculated with the SAP 2000 programs by taking constant tension and compression reinforcement ratios, transverse reinforcement diameter and spacing’s and changing the net span/depth ratio and concrete compressive strengths. In this study, real material behaviour was taken into account. Inelastic behaviors of reinforced concrete coupling beams are investigated from the moment-curvature relations. The damage limit values given in TSC (2018) were calculated for reinforced concrete coupling beam models using the data obtained from moment-curvature relationships of conventionally reinforced concrete coupling beams models. Strain values are calculated for the collapse prevention (CP), controlled damage (CD) and limited damage (LD) performance levels defined in TSC (2018). Three different damage limits and unit strain values corresponding to these damage limits were examined for conventionally reinforced concrete coupling beams. The performance levels of the concrete and reinforcement steel deformations and plastic rotations were calculated for different performance levels of conventional reinforced concrete coupling beams. Damage limits of plastic rotations of the CP and CD performance levels are defined as functions of yield curvature, maximum curvature, plastic hinge length, shear length, and longitudinal reinforcement diameter. In this study; it has been observed that the concrete compressive strength affect the yield moment (M_y), plastic rotation limits (θ_P^((CD)) and θ_P^((CP)) ) for performance levels of CP and CD of conventional reinforced coupling beams. It is proven that the net span depth to ratio (l_n/h) effect the; plastic rotation limits (θ_P^((CD))and θ_P^((CP))) of the CP and CD performance levels and yield chord rotation (θ_y) for the conventional reinforced concrete coupling beams.
