Book excerpt: This report describes analytical and experimental studies focused on identifying those situations where the size effect in shear is significant in concrete members. When a series of geometrically similar reinforced concrete members fail in shear, the shear stress at failure sometimes substantially decreases as the size of the member increases. The authors conclude that columns which contain only small amounts of shear reinforcement, are subjected to low axial loads, and have ratios of column height to member thickness greater than about 2.5 are particularly sensitive to the size effect in shear. The report demonstrates that analytical methods based on the modified compression field theory are capable of predicting reasonably well the magnitude of the size effect in shear.

Book excerpt: To investigate the influence of the longitudinal reinforcement ratio as well as the presence of minimum transverse reinforcement on the shear properties of very large reinforced concrete members, a total of four 2-meter deep spans with varying amount of longitudinal and transverse reinforcement were constructed and tested. Consistency of the Modified Compression Field Theory in predicting shear strength of the tested members is observed throughout this research project. A simplified relationship relating the longitudinal reinforcement ratio with the overall member shear strength is then proposed and compared with the experimental observations. Good correlation between the predictions and test observations is observed.

This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Infrastructure commonly built today incorporates very thick reinforced concrete members that serve as critical elements in the load-carrying system of the structure. Certain design codes specify that members such as mat foundations and transfer slabs in high-rise buildings can be designed without shear reinforcement, allowing for more economical constructability. Omission of shear reinforcement results in structures being susceptible to the well-established size effect, and thus prone to brittle shear failures. The research comprised in this thesis focuses on investigating the applicability of international design codes in predicting the shear strength of very thick concrete members. To this end, a specimen representing a 4 m thick slab strip and a 300 mm thick companion strip were constructed and tested to failure. Results from the experimental program support the recommendation to use at least minimum shear reinforcement in large-scale structures to yield safe designs.

This book was released on 1999 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concern about the shear capacity of large, lightly reinforced high-strength concrete beams was the motivation for this investigation. The objectives of this study were to investigate the influence of concrete strength and main longitudinal reinforcement ratio on the shear capacity of large, lightly reinforced concrete members with, and without, transverse reinforcement. In addition, the test results were used to assess the performance of the North American code provisions, ACI 318-95 and CSA A23.3-94 (General Method). The following observations and conclusions resulted from this study: (i) Overall, the General Method yielded much better predictions than the ACI approach. For the 12 tests, the average ratio of the experimental shear failure load to the predicted shear failure load for the ACI Method and the General Method was 0.74 (Coefficient of Variation = 23%) and 0.98 (C.O.V. = 15.3%), respectively. (ii) The five beam specimens constructed with 1% longitudinal reinforcement, without stirrups, and concrete strengths of 20 MPa, 32 MPa, 38 MPa, 65 MPa, and 80 MPa, respectively, had essentially the same ultimate shear capacity. No benefit was realized in the shear capacity, for the higher strength concrete beams. In fact, the beam specimen with the 80 MPa concrete had the lowest shear capacity. (iii) The implementation of high-strength concrete proved to be beneficial only when transverse reinforcement was utilized.

Available in PDF, EPUB and Kindle. Book excerpt: To obtain experimental data about the shear capacity of very large concrete members, four tests involving 2m deep beams, which are believed to be the largest beam-type specimens tested in North America, were conducted. The four sections studied contained various amounts of shear reinforcement. The following conclusions were arrived at from this study. (1) The specimen not containing transverse reinforcement failed at a shear which was only 47% of the failure load predicted by the shear provisions of the current ACI Building Code. (2) Providing a small amount of shear reinforcement greatly enhanced the response of the beams in terms of shear capacity and ductility. For the same total amount of stirrups the shear capacity increased as the spacing of transverse reinforcement decreased. (3) The procedures in the CSA code based on The Modified Compression Field Theory yield generally good estimates of failure for all of the specimens.
