  2. Joining technology - Wikipedia

    en.wikipedia.org/wiki/Joining_technology

    The joining technology is used in any type of mechanical joint which is the arrangement formed by two or more elements: typically, two physical parts and a joining element. The mechanical joining systems make possible to form a set of several pieces using the individual parts and the corresponding joining elements.

  3. Edge jointing - Wikipedia

    en.wikipedia.org/wiki/Edge_jointing

    When two such edges are brought together and clamped, the sprung edges create greater tension at the ends of the join, which assists in creating a seamless joint. When using a hand plane to perform this operation, two boards are often clamped face to face in the vice and both jointed at once, creating two edges that are mirror images of one ...

  4. Expansion joint - Wikipedia

    en.wikipedia.org/wiki/Expansion_joint

    A expansion joint, or movement joint, is an assembly designed to hold parts together while safely absorbing temperature-induced expansion and contraction of building materials. They are commonly found between sections of buildings , bridges , sidewalks , railway tracks , piping systems , ships , and other structures.

  5. Scarf joint - Wikipedia

    en.wikipedia.org/wiki/Scarf_joint

    The two equations that give a maximum axial force are F=σ/sin(α)^2 and F=σ/sin(2α), where α is the angle from the horizontal to the joint. Both should be evaluated for a given problem, and the smaller F of the two is the magnitude of the maximum allowable axial force. The first equation accounts for failure in tension.

  6. Zeppelin bend - Wikipedia

    en.wikipedia.org/wiki/Zeppelin_bend

    The zeppelin is therefore tied with two loose ends (i.e. no existing tension) ending with a simple knot on each, but woven to each other in a pattern specific to zeppelin. Butterfly bend, Hunter's bend, and Ashley's bend also weave one simple knot on either end but use their own different patterns.

  7. Tilt up - Wikipedia

    en.wikipedia.org/wiki/Tilt_up

    Tilt-up, tilt-slab or tilt-wall is a type of building and a construction technique using concrete. Though it is a cost-effective technique with a shorter completion time, [ 1 ] poor performance in earthquakes has mandated significant seismic retrofit requirements in older buildings.

  8. Arching or compressive membrane action in reinforced concrete ...

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

    Since the 1950s there have been several attempts to develop theories for arching action in both one and two-way slabs. [5] [6] [7] One of the principal approaches to membrane action was that due to Park [8] which has been used as a basis for many studies into arching action in slabs. Park's approach was based on rigid plastic slab strip theory ...

  9. Neighbor joining - Wikipedia

    en.wikipedia.org/wiki/Neighbor_joining

    We then proceed to update the initial distance matrix into a new distance matrix (see below), reduced in size by one row and one column because of the joining of with into their neighbor . Using equation ( 3 ) above, we compute the distance from u {\displaystyle u} to each of the other nodes besides a {\displaystyle a} and b {\displaystyle b} .
