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 ...
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]
The rebar cages can also be installed inside printed concrete formworks in non-structural members, and the holes are filled with grout. This method of post-installed reinforcement has proven to be cost-effective; however, it requires attention to the interface between steel and the printed concrete. [12]
It is made of reinforced concrete clad in a mosaic of thousands of triangular soapstone tiles. [4] Many different types of structures and components of structures can be built using reinforced concrete elements including slabs, walls, beams, columns, foundations, frames and more. Reinforced concrete can be classified as precast or cast-in-place ...
The Wood–Armer method is a structural analysis method based on finite element analysis used to design the reinforcement for concrete slabs. [1] This method provides simple equations to design a concrete slab based on the output from a finite element analysis software.
The modified compression field theory (MCFT) is a general model for the load-deformation behaviour of two-dimensional cracked reinforced concrete subjected to shear. It models concrete considering concrete stresses in principal directions summed with reinforcing stresses assumed to be only axial.
The electrical resistivity of the concrete cover layer decreases due to: [7] Increasing concrete water content; Increasing concrete porosity; Increasing temperature; Increasing chloride content; Decreasing carbonatation depth; When the electrical resistivity of the concrete is low, the rate of corrosion increases.
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– Test methods for fibres in concrete; ASTM A820-16 – Standard Specification for Fiber-Reinforced Concrete (superseded)
