ESTIMATION OF YIELDING DRIFT FOR REINFORCED CONCRETE BEAM

Abstract

A method was proposed to estimate the yielding drift of a beam in a reinforced concrete frame. The drift consists of four components. These are (1) flexural deformation ; (2) shear deformation ; (3) additional deformation due to bar slip from a joint, and (4) additional deformation due to strain shift along a beam bar. The calculation method of each drift component was proposed. The calculated drift components by the proposed method and by other authors' methods were compared with experimental ones. The drift by the proposed method agreed well with test results.
