Concrete which is subjected to long-duration forces is prone to creep. The density of concrete varies, but is around 2,400 kilograms per cubic metre (150 lb/cu ft). [1] Reinforced concrete is the most common form of concrete. The reinforcement is often steel rebar (mesh, spiral, bars and other forms). Structural fibers of various materials are ...
(2) The thermal expansion coefficients of concrete and steel are so close (1.0 × 10 −5 to 1.5 × 10 −5 for concrete and 1.2 × 10 −5 for steel) that the thermal stress-induced damage to the bond between the two components can be prevented. (3) Concrete can protect the embedded steel from corrosion and high-temperature induced softening.
Marcus's method is a structural analysis used in the design of reinforced concrete slabs.The method was developed by Henri Marcus and described in 1938 in Die Theorie elastischer Gewebe und ihre Anwendung auf die Berechnung biegsamer Platten. [1]
A reinforced concrete column is a structural member designed to carry compressive loads, composed of concrete with an embedded steel frame to provide reinforcement. For design purposes, the columns are separated into two categories: short columns and slender columns.
Bamboo reinforcement, including bamboo wrapped in steel wires has been proposed as reinforcement for traditional concrete elements as early as 2005, [26] with recent studies suggesting possible applications in 3D-printed concrete. This technique has the advantage of producing potentially 50 times less carbon emissions than traditional steel ...
Concrete creep is essentially the sagging of concrete over time. Creep and shrinkage of concrete are two physical properties of concrete.The creep of concrete, which originates from the calcium silicate hydrates (C-S-H) in the hardened Portland cement paste (which is the binder of mineral aggregates), is fundamentally different from the creep of metals and polymers.
An extension of the same idea for seismic retrofitting has been experimentally tested for seismic retrofit of California bridges under a Caltrans research project [12] and for seismic retrofit of non-ductile reinforced concrete frames. [13] Pre-stressing can increase the capacity of structural elements such as beam, column and beam-column joints.
The following are several international standards for fiber-reinforced concrete: [35] BS EN 14889-1:2006 – Fibres for Concrete. Steel Fibres. Definitions, specifications & conformity; BS EN 14845-1:2007 – Test methods for fibres in concrete; ASTM A820-16 – Standard Specification for Fiber-Reinforced Concrete (superseded)
