Steel structures are composed of elements which are rolled to a basic cross-section in a mill, and worked to the desired size and form in a fabricating shop or site. A significant difference between steel and concrete constructions is that the designer has more control over the shape of reinforced cement concrete elements.
For building a steel structure, the designer is normally compelled to use standard rolled sections. Fortunately, the variety of steel sections available is so great that any desired structural effect can be achieved in steel.
Steel, as a building material has been used extensively in various types of structures. Some of the examples of civil engineering works in steel are high-rise building skeletons, industrial buildings, transmission towers, railway bridges, overhead tanks, chimneys, bunkers and silos. We shall now discuss the various aspects of design.
The steel structures and the structural elements are analyzed and designed by elastic method (also termed as allowable-stress method or working stress method), plastic method (also called as ultimate load method or loads and load resistance factor method), and the methods based on experimental investigations.

The structural design in a limited sense also deals with the design of various parts or members of a structure. The structural design is governed with the standard specifications. The hand-books are used as working tools in the structural design. When the structural steel is used as the material for the structure, the structural design is known as design of steel structures.
The elastic method is a conventional method and it is in use since long. The stress-strain relationship for the material is assumed to be linear and the deflections are assumed to be small in this method.
The equilibrium equations between the loads applied to the structures and the internal forces of the members meeting at a joint are formulated on the basis of the given geometry of the structure.
The load-deflection relation for the structure is also considered linear. In the elastic method, a member is selected so that under critical combination of the service loads, the calculated maximum stress, based on the elastic analysis shall not exceed a specified permissible stress. The permissible stress in the material is calculated by dividing the yield stress by factor of safety.
In general building construction, all the steel structures and the structural steel components are designed as per IS : 800-1984 Code of Practice for General Construction in Steel. The provisions of the code are thoroughly followed, intelligently interpreted and carefully applied.
CLASSIFICATION OF STRUCTURES
The structures are characterized by their supporting systems. There are one dimensional, two dimensional and three dimensional supporting systems (i.e. line, surface and three dimensional structures) When a supporting system subject to only one type of stresses, then, it is known as basic system. When system is subjected to simultaneously several types of stresses, then it is known as mixed system.
One dimensional supporting system can also be termed as line supporting structures. The line supporting structure is large in one dimension and small in the other two dimensions. The material remains concentrated along a straight. Curved or angular line. A flexible cable is an example for such a line supporting structure.
Two dimensional supporting systems can also be called as surface structure. The surface structure is large in two dimensions and small in third dimension. The material remains distributed along a surface. The surface may be plane or curved. The curved surface may possess single or double curvature.
A surface structure may also consist of line elements that form a continuous structure. The frame structures are examples of surface structures made of line elements. The frame structures are built, by assemblies of elongated members. The shell structures are rigid curved surface structures. The shell structures are built of sheets or plates. The shell roof coverings for large buildings, air plaits, rail road cars, ship bulls, tanks etc. are the examples of shell structures.
Three dimensional structures are large in three dimensions and these structures may have any shape. The three dimensional structures are also called as space structures. The three dimensional frame structures are also space structures.
The structures may be further classified depending on the materials used as plastic structures, aluminum structures, timber structures, reinforced concrete structures and steel structures. The structural steel is used for the steel structures.
The high strength and ductility are the properties of particular importance for the structural use of the steel. The ductility is the unique property of steel by virtue of which it is able to deform substantially either in tension or compression before failure.
