4. Introduction
Structural engineering involves planning, analysis, design, and construction of structures.
Analysis is the process of constructing a mathematical model for the real structure and seeking the numerical solution of the idealized problem.
Certain items in analysis depend on the results of the design.
The main function of a structure is to withstand certain actions that must be transmitted safely to the supports of the structure.
All structures resting on the earth consist of two parts: a superstructure, and an infra-structure (or foundation).

6. Introduction
Structural elements are classified, according to their geometrical features into: massive elements (3-D elements); plates and shells (2-D elements); and beam elements (1-D elements).

7. Introduction
According to their mechanical behaviour, structural forms are classified into: the uniform stress form; and varying stress form.

8. Introduction
Structures may be classified as skeletal structures, and continuum structures.
A skeletal (plane and space) structure is a structure composed of many elements connected together at their ends.
