Steel is the most common material used as reinforcement, but other materials such as fiber-reinforced polymer (FRP) are also used.See all results for this questionWhat is reinforcing steel?Most people are familiar with reinforcing steel, commonly called "rebar". It is used in bridges, buildings, skyscrapers, homes, warehouses, and foundations to increase the strength of a concrete structure. Rebar is used in concrete to provide additional strength, as concrete is weak in tension, while steel is strong in both tension and compression.See all results for this question

May 18, 2015 · In particular, steel-reinforced concrete dominates the AEC sector, where its combined resistance of tensile and compressive forces enables the construction of tall and long-span structures. Despite its near-ubiquitous use, however, steel-reinforced concrete has a fundamental drawback: Given the corrosive tendencies of ferrous metals, it is at locating reinforcing steelconcrete construction magazineSTRUCTURE magazine | Steel Rebar Coatings for Concrete locating reinforcing steelconcrete construction magazineThe use of zinc as a coating to protect steel in concrete structures dates back to about 1900. In the following decades, especially after WWII, zinc was regularly used as a coating material for bridge and highway construction in the northern states of the U.S. and in Canada. Zinc coating protects steel rebar in two ways. First, it serves as a physical barrier between the steel bar and the corrosive environment. Second, it corrodes preferentially and provides sacrificial cathodic protection to the steel. Zinc can be aSee more on structuremag.orgSTRUCTURE magazine | Recommended Details for The location of the top reinforcement in the slab must be clearly indicated on the structural drawings where column-line beams are present. Because the minimum cover to the slab reinforcing bars is usually smaller than that of the beam reinforcing bars, the slab bars are typically placed above the top bars in the beam and in the same plane as locating reinforcing steelconcrete construction magazine
This system has been developed for use in building floor construction, specifically for typical rectangular or square column bay areas of around 1,000 square feet. One of the most economical and widely used floor framing systems is the third-point loading of two in-fill beams on girders which span between columns (Figure 1). Conventional composite steel-concrete floor framing consists of rather deep steel beams and girders which provide the most cost-effective design in terms of tonnage of structural steel uSee more on structuremag.orgRepair of Damaged Steel-Concrete Composite Girders Using locating reinforcing steelconcrete construction magazineNov 04, 2003 · Damaged steel-concrete composite girders can be repaired and retrofitted by epoxy bonding carbon fiber-reinforced polymer (CFRP) laminates to the critical areas of tension flanges.
