Traditionally, the study of reinforced concrete design begins directly with a chapter on materials, followed by chapters dealing with design. In this book, a departure is made from that convention. It is desirable for the student to have first an overview of the world of reinforced concrete structures, before plunging into the finer details of the subject. Accordingly, this chapter gives a general introduction to reinforced concrete and its applications. It also explains the role of structural design in reinforced concrete construction, and outlines the various structural systems that are commonly adopted in buildings.

That concrete is a common structural material is, no doubt, well known. But, how common it is, and how much a part of our daily lives it plays, is perhaps not well known — or rather, not often realised. Structural concrete is used extensively in the construction of various kinds of buildings, stadia, auditoria, pavements, bridges, piers, breakwaters, berthing structures, dams, waterways, pipes, water tanks, swimming pools, cooling towers, bunkers and silos, chimneys, communication towers, tunnels, etc.

It is the most commonly used construction material, consumed at a rate of approximately one ton for every living human being. “Man consumes no material except water in such tremendous quantities” (Ref. 1.1). Pictures of some typical examples of reinforced concrete structures are shown in Figs 1.1−1.5. Perhaps, some day in the future, the reader may be called upon to design similar (if not, more exciting) structures! The student will do well to bear this goal in mind.

Concrete may be defined [Ref. 1.2] as any solid mass made by the use of a cementing medium; the ingredients generally comprise sand, gravel, cement and water. That the mixing together of such disparate and discrete materials can result in a solid mass (of any desired shape), with well-defined properties, is a wonder in itself. Concrete has been in use as a building material for more than a hundred and fifty years. Its success and popularity may be largely attributed to (1) durability under hostile environments (including resistance to water), (2) ease with which it can be cast into a variety of shapes and sizes, and (3) its relative economy and easy availability.

The main strength of concrete lies in its compression-bearing ability, which surpasses that of traditional materials like brick and stone masonry. Advances in concrete technology, during the past four decades in particular, have now made it possible to produce a wide range of concrete grades, varying in mass density (1200−2500 kg/m3 ) and compressive strength (10 −100 MPa). Concrete may be remarkably strong in compression, but it is equally remarkably weak in tension! [Fig. 1.6(a)].

Its tensile ‘strength’ is approximately one-tenth of its compressive ‘strength’. Hence, the use of plain concrete as a structural material is limited to situations where significant tensile stresses and strains do not develop, as in hollow (or solid) block wall construction, small pedestals and ‘mass concrete’ applications (in dams, etc.).
