Bending stiffness of cracked reinforced concrete sections defined by Turkish Earthquake Code Section 7 and bending stiffness to be used at the beginnig of push-over analysis, increased the importance of a realistic determination of bending stiffness before collapse. In this study for considering behaviour of reinforced concrete sections under various stress phases, the factors effecting rigidity are revisited. Deflections obtained by using these bending rigidities compared with the published results obtained in various laboratory tests. Some proposals are made depending on the resuls of this work.
