Multistory Buildings

The tallness of a building is relative and can not be defined in absolute terms either in relation to height or the number of stories. But, from a structural engineer's point of view the tall building or multi-storeyed building can be defined as one that, by virtue of its height, is affected by lateral forces due to wind or earthquake or both to an extent that they play an important role in the structural design.

The development of the high-rise building has followed the growth of the city closely. The process of urbanisation, that started with the age of industrialisation, is still in progress in developing countries like India. Industrialisation causes migration of people to urban centres where job opportunities are significant. The land available for buildings to accommodate this migration is becoming scarce, resulting in rapid increase in the cost of land.

Beam-and-Column Construction

This is often called as “skeleton construction”. The floor slabs, partitions, exterior walls etc. are all supported by a framework of steel beams and columns. This type of skeleton structure can be erected easily leading to very tall buildings.

Common types of floor system

The selection of an appropriate flooring in a steel-framed building depends on various factors like the loads to be supported, span length, fire resistance desired, sound and heat transmission, the likely dead weight of the floor, the facilities needed for locating the services, appearance, maintenance required, time required to construct, available depth for the floor etc.

Concrete slabs supported with open-web joists

This is one of the most common types of floor slabs used for steel frame buildings in U.S. Steel forms or decks are usually attached to the joists by welding and concrete slabs are poured on top.

Composite floors with a reinforced concrete slab and steel beams

Composite floors have steel beams bonded with concrete slab in such a way that both of them act as a unit in resisting the total loads. The sizes of steel beams are significantly smaller in composite floors, because the slab acts as an integral part of the beam in compression.
