Steel is a very common construction material, which is used throughout the construction industry. steel is used to form a skeleton for the building and/or structure and holds everything in it place. steel is widely used as a building material. it is because of its mechanical properties, ease and speed of construction and design simplicity. it is extremely easy to adjust or to extend to an existing structure constructed of steel by simply welding or bolting new steel pieces to the existing structure. and it will still give the structure the same amount of strength. structural steel has a wide amount of properties which suit different requirements which are weldability, ductility, strength and corrosion resistance. the extra feature of steel is that it will not break either, when met in contact with excessive load(s). steel can be shaped into several forms and sections for the specific construction purpose which are H section, I section, rectangular hollow section, unequal angles, square hollow section and many other forms and shapes. the introduction of steel firstly began around the 1880s, which was first made in quite large quantities which were then used for rail roads, etc.

early steel frame high rises

while these prodigious structures were the centre of attentio, a new and more significant technology was developing: the steel framed high rise building. it began in chicago, a city whose central business district was growing rapidly. the pressure of land values in the early 1880s led owners to demand taller buildings. the architect and engineer William Le Baron Jenney responded to this challange with the ten storey home insurance company building in 1885, which had a nearly all-steel structure. the frame consisted of cast iro...

Costing

A number of factors can be considered to have a key impact on the price of structural steel frames. All the costs include allowances for a concrete core. The rates have been developed from cost models of the different building types and for each of the average weight of the structural frame has been given.
As already highlighted, before using such ‘standard ranges’ it is important to confirm the anticipated frame weight and variables such as the floor-to-floor heights with the design team to determine whether they are above or below the average and to adjust the rate used accordingly. Similarly, all of the other key cost drivers of complexity, site conditions, location, function, logistics, programme and procurement strategy should be considered in turn.
