This book was released on 1976 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: Results of a study of the response of impulse loaded reinforced concrete beams are presented. The objectives were to develop basic data of the blast-structural response phenomenon for the evaluation of structural survivability, and to compare these data with results of digital computer program, IMPBC, a simulation of the blast-structure interaction. The study included the definition of failure and a method for assessing damage due to blast loading. The reinforced concrete beams were full-sized representations of members found in buildings. There were twelve impulse tests, of which seven were performed on identical beams for which the material properties and steel percentage were typical of average construction practice. The remaining five were of beams having high strength concrete (two tests), high strength steel (one test), and greater steel percentage (two tests). Impulse loading was obtained from the detonation of 214-pound spherical pentolite charges suspended above the beams. The high strength concrete beams exhibited the greatest resistance to damage from impulse loading. These members experienced little distress while the members with increased steel area and greater moment capacity suffered the greater damage. This was predicted by the damage criterion presented in this report.

This book was released on 1968 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first phase of a study into the shear and bond capacity of high-strength reinforced concrete beams under static and dynamic load is reported. A static load test program involving midspan loads on two flexure and 11 shear beams with a 6-inch by 12-inch cross section and nine anchorage bond specimens containing numbers 8, 11, or 14S bars was conducted. Duplicate flexure specimens, shear specimens, and numbers 8 and 11 bar bond specimens were subjected to dynamic loading from a falling mass that struck each beam through an impulse-controlling cushion of vermiculite concrete. The concrete strength in the test beams varied from 6000 to 9100 psi. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: An investigation was made of the hinging mechanism in under-reinforced concrete beams subjected to static or dynamic loads. Two test series on simply supported beams with a 6-foot span length were conducted. In one series, 11 beams were subjected to two concentrated loads symmetrically placed 18 inches apart; the primary variable was the magnitude of the step load pulse (1.0 to 1.4 times the static yield load). In the other series, 15 beams were subjected to a concentrated load at midspan; the primary variables were the type of load (static or dynamic), the amount of tension reinforcement (p=0.9,1.3, and 2.0, p1/p=0.67), and the size of the transverse reinforcement (1/8- and 1/4-inch round bars and No. 3 deformed bars). Hinge development was similar in the statically and dynamically loaded beams and resulted from the formation and propagation of a yielded zone or zones in the tension reinforcement. Strain hardening of the tension reinforcement increased the static resistance above the yield value; the increase ranged from 5 to 60 percent. Although decreasing the amount of tension reinforcement increased the deflection of certain stages, the ultimate rotation capacity was not significantly affected. In addition, the size of the transverse reinforcement had a negligible effect on the ultimate rotation capacity. (Author).

This book was released on 1971 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: Behavioral equations were developed for reinforced concrete deep beams, especially in the realm of shear capacity. A series of static and dynamic beam tests was performed to aid in the development of this objective. Static shear behavior equations for deep beams were derived on the lower boundary of reinforced concrete deep beam data represented by research from this report and other research comprising 73 tests. Equations for a total static shear capacity are given which conservatively predict shear capacities of the beam tests considered. (Author).

This book was released on 2012-01-28 with total page 567 pages. Available in PDF, EPUB and Kindle. Book excerpt: High Performance Fiber Reinforced Cement Composites (HPFRCC) represent a class of cement composites whose stress-strain response in tension undergoes strain hardening behaviour accompanied by multiple cracking, leading to a high strain prior to failure. The primary objective of this International Workshop was to provide a compendium of up-to-date information on the most recent developments and research advances in the field of High Performance Fiber Reinforced Cement Composites. Approximately 65 contributions from leading world experts are assembled in these proceedings and provide an authoritative perspective on the subject. Special topics include fresh and hardening state properties; self-compacting mixtures; mechanical behavior under compressive, tensile, and shear loading; structural applications; impact, earthquake and fire resistance; durability issues; ultra-high performance fiber reinforced concrete; and textile reinforced concrete. Target readers: graduate students, researchers, fiber producers, design engineers, material scientists.

This book was released on 2013 with total page 184 pages. Available in PDF, EPUB and Kindle. 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.
