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.
The cross-section of the column is uniform throughout its length. The direct stress is very small as compared to the bending stress (the material is compressed only within the elastic range of strains). The length of the column is very large as compared to the cross-sectional dimensions of the column. The column fails only by buckling.
Therefore, a 152x152x23UC would be a column section (UC = universal column) of approximately 152 mm (6.0 in) depth, 152 mm width and weighing 23 kg/m (46 lb/yd) of length. [ 10 ] In Australia , these steel sections are commonly referred to as Universal Beams (UB) or Columns (UC).
By expressing a distance in c.t.c., one can measure distances between columns with different diameters without confusion. This concept applies to other architectural features that may have variable diameters/widths and spacings, such as pillars or ceiling beams and baffles.
A beam is a structural element that primarily resists loads applied laterally across the beam's axis (an element designed to carry a load pushing parallel to its axis would be a strut or column). Its mode of deflection is primarily by bending , as loads produce reaction forces at the beam's support points and internal bending moments , shear ...
The beams are continuously formed, so the length of the beam is limited only to the maximum length that can be handled and transported. Typical widths are 3 + 1 ⁄ 2, 5 + 1 ⁄ 4 or 7 inches (89, 133 or 178 mm); typical depths are 9 + 1 ⁄ 2, 11 + 7 ⁄ 8, 14, 16 and 18 inches (240, 300, 360, 410 and 460 mm). Typically the beams are made to a ...
The effective length is calculated from the actual length of the member considering the rotational and relative translational boundary conditions at the ends. Slenderness captures the influence on buckling of all the geometric aspects of the column, namely its length, area, and second moment of area .
Lateral Queen – a pair of braced posts between a tie beam and collar beam. Prince – A strut associated with a king post truss. princess – A strut associated with a queen strut but shorter. [25] Crown – A post on a tie beam or collar beam carrying a crown plate. [26] Crown strut: A piece similar to a crown post but not carrying a plate. [27]
