Preface
Theory of the engineering structures is a fundamental science. Statements and methods
of this science are widely used in different fields of engineering. Among them
are the civil engineering, ship-building, aircraft, robotics, space structures, as well
as numerous structures of special types and purposes – bridges, towers, etc. In recent
years, even micromechanical devices become objects of structural analysis.
Theory of the engineering structures is alive and is a very vigorous science.
This theory offers an engineer-designer a vast collection of classical methods of
analysis of various types of structures. These methods contain in-depth fundamental
ideas and, at the present time, they are developed with sufficient completeness
and commonness, aligned in a well-composed system of conceptions, procedures,
and algorithms, use modern mathematical techniques and are brought to elegant
simplicity and perfection.
We now live in a computerized world. A role and influence of modern engineering
software for analysis of structures cannot be overestimated. The modern
computer programs allow providing different types of analysis for any sophisticated
structure. As this takes place, what is the role of classical theory of structures
with its in-depth ideas, prominent conceptions, methods, theorems, and principles?
Knowing classical methods of Structural Analysis is necessary for any practical
engineer. An engineer cannot rely only on the results provided by a computer. Computer
is a great help in modeling different situations and speeding up the process
of calculations, but it is the sole responsibility of an engineer to check the results
obtained by a computer. If users of computer engineering software do not have sufficient
knowledge of fundamentals of structural analysis and of understanding of
physical theories and principal properties of structures, then he/she cannot check
obtained numerical results and their correspondence to an adopted design diagram,
as well as explain results obtained by a computer. Computer programs “. . . can make
a good engineer better, but it can make a poor engineer more dangerous” (Cook
R.D, Malkus D.S, Plesha M.E (1989) Concepts and applications of finite element
analysis, 3rd edn. Wiley, New York). Only the knowledge of fundamental theory
of structures allows to estimate and analyze numerical data obtained from a computer;
predict the behavior of a structure as a result of changing a design diagram
and parameters; design a structure which satisfies certain requirements; perform
