***** Professor,
Dept. ofof Architecture andSeismic performance of flexure-dominant reinforced concrete walls with deformed bars at crack control joints as
crack inducers is experimentally and numerically investigated. Deformed-bar-crack-inducers have been proposed foruse in structural walls in mid-to-high-rise housing complexes.
A couple of half-scale two-story RC wall test specimens were constructed on a stiff base foundation. They had
boundary columns at both sides with a stiff girder at the top for loading. The wall in each story was 1100 mm high,2200 mm long, and 100 mm thick. The thickness was reduced to 80 mm at the crack control joints, two of which werelocated at the boundary between wall and columns, and one of which was at the mid-span. The test parameter was
the diameter of the crack-inducing bars; type D6 for test specimen FWP63R07 and type D16 for FWP63R20. The
nominal compressive strength of concrete in design was 30 MPa and longitudinal reinforcements of the beams andcolumns were type SD345. The other reinforcing bars were type SD295A. To design the walls not to fail in shear, theultimate shear strength of the walls was 1.91 times greater than the ultimate flexural capacity without considering
the reduction in the wall thickness at the crack control joints. While the two boundary columns were subjected to1080 kN as the axial load, the lateral loading was applied at the mid-span of the top beam.
By using the finite element analysis program DIANA9.6, a detailed numerical study on the structural response of
the walls such as load-drift angle relationship, stress-strain distribution of the crack-inducing bars, stress
distribution of the deformed bars, and the vertical displacements of the boundary columns’ bases was carried out as
well.
The following conclusions can be drawn from the experimental and numerical works of this study.
 (1) The crack-control joints at the boundary columns’ faces did not contribute to the overall collapse mechanism.
(2) At drift angel by 0.5% the two test specimens exhibited identical load-deflection relationships. No influence ofshrinkage cracks and bar diameters were found.
(3) The test specimen with type D6 crack-inducing bar reached its ultimate strength at R=1.5% while the other test
specimen with larger crack-inducing bar diameter (type D16) exhibited its ultimate strength at R=1.0%. It seems
that the difference in crack-inducing bar diameter could contribute to such a discrepancy.
(4) It was found that the crack-inducing bar diameter had no influence on the vertical sliding displacement of thecrack-control joints.
(5) It was found the conventional equations can be applied for evaluating the initial stiffness, flexural cracking
strength, and the bending ultimate strength of the wall test specimens when neglecting the wall cross-section
reductions at the crack-control joints.
(6) The predicted ultimate flexural strength of the two test specimens was approximately 20% smaller than the test
results.
(7) The developed finite element model in this study could simulate the lateral load-deflection of the test specimens
until almost the ultimate capacities, the vertical displacement of the walls’ bases before reaching the tensile
rupture of their longitudinal reinforcements, and the strain distribution of the crack-inducing bars at R=0.25%.
By verifying the test and FE results, a series of parametric studies investigating the influence of crack-inducing
bar diameter, number of crack control joint, wall reinforcement ratio, and concrete strength is under development.
