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.
ASEP was established in 1961 to promote the advancement of Filipino civil engineers in the field of structural engineering. [1] [2] The publication of the National Structural Code of the Philippines (NSCP) and the referral codes of the Philippine National Building Code were published by the organization.
This is due to the fact that the inorganic matrix has shown numerous advantages, compared with the organic counterpart (FRP), including a better response when applied to fragile substrates such as masonry and reinforced concrete, thanks to the greater compatibility of the mortar layer when applied on such substrates.

A clear distinction is made between the ultimate state (US) and the ultimate limit state (ULS). The Ultimate State is a physical situation that involves either excessive deformations leading and approaching collapse of the component under consideration or the structure as a whole, as relevant, or deformations exceeding pre-agreed values.
All concrete structures will crack to some extent, due to shrinkage and tension. 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.
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 ...
Conventionally the term concrete refers only to concrete that is reinforced with iron or steel. However, other materials are often used to reinforce concrete e.g. organic and inorganic fibres, composites in different forms. While compared to its compressive strength, concrete is weak in tension. Thus adding reinforcement increases the strength ...
A concrete spacer with a plastic clip in use Concrete spacers in a precast element Diaphragm wall block on rebar for a Diaphragm wall. A rebar spacer is a short, rod-like device used to secure reinforcing steel bars, or rebar, within cast assemblies for reinforced concrete structures. The rebar spacers are fixed before the concrete is poured ...
