| Summary |
"In this study an attempt was made to examine experimentally the shear flow zone in reinforced concrete members subjected to pure torsion. The strain distribution through the shear flow zone was measured using a special concrete-embeddable strain gage units that were especially developed for this purpose. The performance and the reliability of the embeddable units were assessed experimentally prior to their application. The units were used to measure the shear flow zone in four full-size beams. It was found that the actual shear zone is smaller than the prediction of the ACI 318-95. The strain distribution through this zone was rather parabolic [sic] which indicated that reinforcement can affect the strain distribution. A rational definition of the shear flow centerline was introduced. Furthermore, discripancy with tests results were discussed. The ACI 318-95 formula for predicting the cracking torque was assessed and found to underestimate the cracking torque, a more accurate approach was proposed. Finally, an attempt was made to investigate the softening of diagonals concrete under torsion"--Abstract, leaf iii. |
