    It consists of a steel strand which is similar to the strand used in post-tensioned concrete. Beam – is a structural element that primarily resists loads applied laterally to the beam's axis. Its mode of deflection is primarily by bending. The loads applied to the beam result in reaction forces at the beam's support points.

    In the illustration of the column formwork above, the 'column clamps' are closer together at the bottom. Note that the column is braced with steel adjustable 'formwork props' and uses 20 mm 'through bolts' to further support the long side of the column. Some models of "permanent formwork" also can serve as extra reinforcement of the structure.

    en.wikipedia.org/wiki/Lally_column

    A Lally column is a round or square thin-walled structural steel column filled with concrete, [1] and oriented vertically to provide support to beams or timbers stretching over long spans. Lally columns are an engineered component and as such must be installed exactly as the design engineer specified.

  8. Column - Wikipedia

    en.wikipedia.org/wiki/Column

    A steel column is extended by welding or bolting splice plates on the flanges and webs or walls of the columns to provide a few inches or feet of load transfer from the upper to the lower column section. A timber column is usually extended by the use of a steel tube or wrapped-around sheet-metal plate bolted onto the two connecting timber sections.

  9. I-beam - Wikipedia

    en.wikipedia.org/wiki/I-beam

    The dimension of a wide-flange I-beam. In the United States, steel I-beams are commonly specified using the depth and weight of the beam. For example, a "W10x22" beam is approximately 10 in (254 mm) in depth with a nominal height of the I-beam from the outer face of one flange to the outer face of the other flange, and weighs 22 lb/ft (33 kg/m).
