Reinforced concrete (RC) is a composite material in which concrete's relatively low tensile strength and ductility are counteracted by the inclusion of reinforcement having higher tensile strength and/or ductility. The reinforcement is usually, though not necessarily, steel reinforcing bars (rebar) and is usually embedded passively in the concrete before the concrete sets. Reinforcing schemes are generally designed to resist tensile stresses in particular regions of the concrete that might cause unacceptable cracking and/or structural failure. Modern reinforced concrete can contain varied reinforcing materials made of steel, polymers or alternate composite material in conjunction with rebar or not. Reinforced concrete may also be permanently stressed (in compression), so as to improve the behaviour of the final structure under working loads. In the United States, the most common methods of doing this are known as pre-tensioning and post-tensioning.
For a strong, ductile and durable construction the reinforcement needs to have the following properties at least:
This video provides an explanation and overview for the design process for a singly reinforced concrete beam.
This is a part of the Reinforced Concrete video series. It introduces reinforced concrete. There is some background noise in the video due to strong wind from a cyclone passing through when I was recording it.
Jamy explains how the transition took place from the time of smooth rebars to Hérisson® rebar couplers: with unrivalled qualities of resistance, the rebar couplers ensure reinforced concrete with maximum safety. Concrete and steel have never been so intimately unified! http://armaturis.com
World-leading reinforced concrete expert Professor Tim Ibell introduces viewers to reinforced concrete. This is the second in the Bare Essentials of Concrete series: the key things people who are studying construction or who are working in construction need to understand about concrete. Professor Ibell is Associate Dean at the Faculty of Engineering and Design at the University of Bath. In this video he describes the underlying reasons why we reinforce concrete, how concrete and steel work together and the main principles that engineers apply to produce reinforced concrete structures. Learning outcomes The compression and tension effects of loading a concrete beam. How steel counters the weakness of concrete in tension. A new material call reinforced concrete.

Reinforced Concrete Building Design - Sketch Up Animation. (Reinforcements Details) (Sun 08.02.15) by Al Jameel.
Corrosion of reinforcing steel is the predominant cause of failure in reinforced concrete structures leading to financial losses, safety risks and environmental impact. The understanding of the mechanisms and kinetics of the degradation processes of concrete allows us to improve the design of structures to enhance durability and extend service-life. Iron ore is mined from earth where it exists as oxides. It is refined in furnaces at high temperatures to make steel. Then it is protected and fabricated into different types of structures. However, throughout its life, steel is not stable and has the potential to oxidize and return to its original nature. When embedded in concrete, steel is passivated by concrete’s high alkalinity making it resistant to corrosion. However, the ingress ...
This video demonstrates a four-point bending test on an over-reinforced concrete beam. Learning Outcomes. Viewers will gain an improved understanding of: - Brittle failure in reinforced concrete. - How the quantity of reinforcement in a beam can affect the failure mode. The beam demonstrates brittle behaviour as it is loaded to failure. The video demonstrates how providing too much steel reinforcement in the tension zone of a beam will cause it to fail in a sudden brittle manner as the concrete fails in compression.

Read your free e-book: http://copydl.space/mebk/50/en/B01G6498X8/book The history of vintage structural concrete systems, in general, is much less documented than the history of architecture. This lack of documentation can be traced to some degree to the general lack of interest by the public toward the hidden structuralcomponents of a building that are typically enclosed by interior architectural finishes,facades, or other building envelope systems. In addition, as new materials, technologies, and methods of construction and engineering analysis became available over time and were readily embraced by the construction industry and design engineers (especially if there were economies involved with the newer systems), previously used systems were quickly discarded and forgotten.this publicat...

Read your free e-book: http://copydl.space/mebk/50/en/B0172Q0R3Y/book Construction of slabs in areas with weak soil conditions has commonly used pile-supported slab structural design so that the adverse effects of soil-structure interaction in terms of differential settlement, or long-term serviceability problems are avoided. In this application, the construction of slabs on closely spaced pile caps (typical span-depth ratios between 8 and 30) is referred to as elevated ground slabs (egss). These slabs may be subjected to moderately high loading, such as concentrated point loading of up to 44 kip (150 kn) and uniformly distributed loadings of 1000 lb/ft2 (50 kn/m2). The dynamic loadings may be due to moving loads such as forklifts, travel lifts, and other material handling equipment. Fiber...
