Book excerpt: After the Canterbury earthquakes, engineers noticed similar cases of failure in low-rise reinforced concrete structures, where it was observed that only a few large cracks initiated in the structural members, which differs from laboratory results (fine distributed cracks across span). It was speculated that several aspects could have led to this discrepancy in results, the first could be the bond strength between steel reinforcement and concrete, where it was ventured that a high bond strength could prevent the even distribution of strains across the steel which could lead to concentrated strain and thus large cracking; secondly, the loading history that was subjected to these structural members are unknown, as not much detailed information was recorded on whether the later observed major flexural cracks were caused by an accumulation of loadings histories applied over time (first being the Darfield main shock in February, then in June and finally in December; thirdly, is whether the rate of loading (fast seismic vibrations) in most of these lightly reinforced concrete buildings could have contributed to the observed phenomenon. This thesis focuses on investigations into the behavior of reinforced concrete beams under the application of varying high strain-rate cyclic loadings. The specimens used for the experiment consisted of three nominally identical lightly reinforced concrete beams of dimensions 250 mm width and 400 mm depth with a span of 4.6 m long designed according to NZS3101:2006 Concrete Structures Standard. Results obtained indicated that the faster rates of loading does indeed have a tendency to lead to fewer but larger cracks in the lightly reinforced concrete beams near the column face, a possible justification for this could be that the strains induced by the high rate of loading does not have enough time to properly distribute along the longitudinal reinforcements within the beam, thus causing the high concentration of strain at a particular point to cause this type of large flexural cracking.

Book Progressive Collapse Resilience of Concrete Structures Mechanisms Simulations and Experiments

Download or read book Progressive Collapse Resilience of Concrete Structures Mechanisms Simulations and Experiments written by Kai Qian and published by Springer Nature. This book was released on 2023-07-08 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book introduces the comprehensive analysis methodology regarding progressive collapse, and the critical issues may happen in concrete structures. Main topics include: the influential parameters of the development of the main load-resisting mechanisms; the dynamic effects with sudden column removal scenarios; the contribution of non-structural components to improve the resilience of concrete structures; uncertainties in progressive collapse analysis. Based on the empirical research of the author and his team, the book provides valuable knowledge in the field of progressive collapse and bridges the gap between academic research and practice.

Book Effects of Impulsive Loads on Fiber reinforced Concrete Beams

Download or read book Effects of Impulsive Loads on Fiber reinforced Concrete Beams written by James P. Romualdi and published by . This book was released on 1965 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes an investigation of the effect of a destructive impulse load upon fibre reinforced concrete beams. Concrete develops tension cracks as a result of minute flaws that are inherent in its nature. A method of arresting these cracks by placing short lengths of randomly spaced fine wire within the concrete mix is described. The results of the studies indicate that (1) the fibres increase the tensile strength of the concrete by as much as 100 percent for static loading, and (2) the material exhibits considerable post-cracking strength. These two effects increase the ability of the material to absorb energy.
