NON-LINEAR ANALYSIS OF EFFECT OF CONFINEMENT REGIONS ON MOMENT CURVATURE BEHAVIOR OF SHEAR WALL (THEORETICAL STUDY)

Computer program which investigates the effectiveness of confinement regions of shear walls was developed.Specimens which have unique web reinforcement and different confinement regions were analyzed by using this computer program. Data needed for theoratical computations were obtained by tensile testing of steel rods and by concrete specimen tests. Mander Method was applied to reflect confined concrete behavior. Strain hardening behavior of steel was included in computations. Effect of stirrup spacing and hook reinforcement was introduced together and seperately to understand the moment-curvature response of specimens.
