  2. Modified compression field theory - Wikipedia

    en.wikipedia.org/wiki/Modified_Compression_Field...

    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 ACI Building Code Requirements put the following restrictions on amount of spiral reinforcement. ACI Code 7.10.4.2: For cast-in-place construction, size of spirals shall not be less than 3/8 in. diameter. ACI Code 7.10.4.3: Clear spacing between spirals shall not exceed 3 in., nor be less than 1in.

  4. Shear wall - Wikipedia

    en.wikipedia.org/wiki/Shear_wall

    A typical timber shear wall consists of braced panels in the wall line, constructed using structural plywood sheathing, specific nailing at the edges, and supporting framing. A shear wall is an element of a structurally engineered system that is designed to resist in- plane lateral forces, typically wind and seismic loads.

    ACI 318 Building Code Requirements for Structural Concrete provides minimum requirements necessary to provide public health and safety for the design and construction of structural concrete buildings. [6] It is issued and maintained by the American Concrete Institute. [7] The latest edition of the code is ACI 318-19.

  6. Wall footing - Wikipedia

    en.wikipedia.org/wiki/Wall_footing

    Wall Footing . A wall footing or strip footing is a continuous strip of concrete that serves to spread the weight of a load-bearing wall across an area of soil. [1] It is a component of a shallow foundation. [1] Wall Footing. Wall footings carrying direct vertical loads might be designed either in plain concrete or in reinforced concrete.

    en.wikipedia.org/wiki/Arching_or_Compressive...

    The derivation of the maximum arching moment of resistance of laterally restrained concrete bridge deck slabs utilised Rankin's [21] idealised elastic-plastic stress-strain criterion for concrete, valid for concrete cylinder strengths up to at least 70N/mm 2, which he had derived on the basis of Hognestad, Hanson and McHenry's [23] ultimate ...

  8. Grade beam - Wikipedia

    en.wikipedia.org/wiki/Grade_beam

    A grade beam or grade beam footing is a component of a building's foundation. It consists of a reinforced concrete beam that transmits the load from a bearing wall into spaced foundations such as pile caps or caissons. [1] It is used in conditions where the surface soil's load-bearing capacity is less than the anticipated design loads.

    The hole should be firestopped to restore the fire-resistance rating of the wall. Instead, it is filled with flammable polyurethane foam . A building code (also building control or building regulations ) is a set of rules that specify the standards for construction objects such as buildings and non-building structures .
