  2. Thermal transmittance - Wikipedia

    en.wikipedia.org/wiki/Thermal_transmittance

    The average thermal insulance of the "bridged" layer depends upon the fraction of the area taken up by the mortar in comparison with the fraction of the area taken up by the light concrete blocks. To calculate thermal transmittance when there are "bridging" mortar joints it is necessary to calculate two quantities, known as R max and R min.

  3. Course (architecture) - Wikipedia

    en.wikipedia.org/wiki/Course_(architecture)

    This is the simplest arrangement of masonry units. If the wall is two wythes thick, one header is used to bind the two wythes together. [3] Header course: This is a course made up of a row of headers. [1] Bond course: This is a course of headers that bond the facing masonry to the backing masonry. [1] Plinth: The bottom course of a wall.

  4. Domain wall (magnetism) - Wikipedia

    en.wikipedia.org/wiki/Domain_wall_(magnetism)

    A domain wall is a gradual reorientation of individual moments across a finite distance. The domain wall thickness depends on the anisotropy of the material, but on average spans across around 100–150 atoms. The energy of a domain wall is simply the difference between the magnetic moments before and after the domain wall was created.

  5. Concrete block - Wikipedia

    en.wikipedia.org/wiki/Concrete_block

    A pallet of "8-inch" concrete blocks An interior wall of painted concrete blocks Concrete masonry blocks A building constructed with concrete masonry blocks. A concrete block, also known as a cinder block in North American English, breeze block in British English, concrete masonry unit (CMU), or by various other terms, is a standard-size rectangular block used in building construction.

    Hong Kong law Chapter 123F, Building (Planning) Regulations, Regulation 23 sect 3 sub-paragraph (a) defined that: Subject to sub-paragraph (b), for the purposes of regulations 19, 20, 21 and 22, the gross floor area of a building shall be the area contained within the external walls of the building measured at each floor level (including any floor below the level of the ground), together with ...

  7. Precast concrete lifting anchor system - Wikipedia

    en.wikipedia.org/wiki/Precast_concrete_lifting...

    For example, some of the anchors shown in figures 4-6, can be placed into thin wall elements as the anchor chair maintains the position relative to the element thickness. As the orientation of the void determines the lift position of the lifting clutch , the wire chair can be secured against the element reinforcement to maintain this ...

  8. Infill wall - Wikipedia

    en.wikipedia.org/wiki/Infill_wall

    The infill wall has the unique static function to bear its own weight. The infill wall is an external vertical opaque type of closure. With respect to other categories of wall, the infill wall differs from the partition that serves to separate two interior spaces, yet also non-load bearing, and from the load bearing wall.

  9. Anderson's theory of faulting - Wikipedia

    en.wikipedia.org/wiki/Anderson's_Theory_of_Faulting

    Dip is defined as the angle of the fault relative to the surface of the earth, which indicates the plane on which slip will occur. Lastly, in any non-vertical fault, the block above the fault is called the hanging wall, while the blockbelow the fault is called the footwall. [4] Normal and reverse dip-slip faults with labeled hanging wall and ...
