Text 15 basic concepts in the analysis of structures

A structure is built to perform a certain function. To perform this function satisfactory, it must have sufficient strength and rigidity. Economy and good appearance are further objectives of major importance in structural design.

Stress analysis serves as an important guide in so proportioning the members of a structure that the required strength, rigidity and economy will be attained. However rigorous a stress analysis may be, the stresses which will actually occur cannot be predicted with absolute certainty. As actually build, a structure and its loading will always differ somewhat, and may differ appreciably, from the hypothetical structure which serves as a basis for stress analysis. Recognition of this fact, together with considerations of economy in time and design expense, often leads the designer to make assumption known to be correct, and approximations known to introduce errors. Only knowledge of the basic principles of stress analysis can serve as a safe basis for departure from methods more rigorously correct. The assumptions underlying the basic theory and the limitations imposed in the development of basic theorems must be fully understood and constantly kept in mind. If approximate methods arc to be introduced, they must be carefully studied in order to ascertain that they may be safely and properly applied to a given problem.

Most of the materials used in building structures follow Hooke’s law: Within a certain range dependent upon the material considered, stress and strain are directly proportional to each other. If stresses do not exceed a certain value termed tins elastic limit for the material considered, the strains will vanish if the stress is removed. Materials behaving in this manner are called elastic. Steel, wrought iron, and wood elastic, while it is permissible to consider reinforced concrete as elastic, too, provided the stresses are not too great.

When structure which are composed of elastic members and which rest elastic supports are subjected to the action of forces or to imposed deformations such as the changing of the length of a bar, there are corresponding changing of shape. The movements of points on the structure during such a change are called deflections. Distortions may or may not be accompanied by stresses in the members of structure.
