Columns are stiffened mainly to improve their resistance to bending moments and are often used in conjunction with Moment Connections. Careful selection of the columns and beams will often negate the need for strengthening of the connections, however, there will always be cases where it’s deemed necessary. The method of strengthening is determined by the […]

Columns are essentially compression members, but they may be required to resist lateral forces caused by wind and seismic activity. Additionally, they may be required to resist bending, especially in suspension structures where they act as ‘towers’ or ‘masts’ providing support for tension members. Bending may also be the result of eccentricity of the end-reaction

0The Column Base-Plate is welded tp the base of the column and in turn, fastened to the foundation by means of specially designed Anchor Bolts. They have to deal with a variety of load conditions including, Compression, Shear and Rotational Moments. All column bases will have to deal with a combination of these loads to a greater or

Crane-Columns are a subject unto themselves, they differ from the more conventional column in that they must resist substantial dynamic forces generated by the movement of the crane. These loads include the mass of the crane-gantry itself together with its maximum load carrying capacity, additionally these loads must be factored for the impact of the
Multi-Storey structures generally require that the columns be ‘spliced’ in order to extend their length for the full height of the structure. Splices may be either bolted or welded and its always assumed that welded splices are ‘shop-welded’ while bolted splices are ‘site-bolted’. It is possible to call for a site-welded splice, but making such
