Essential Knowledge Text No.3 Historical development of structural form

Despite the many advantages of computer-aided analysis methods, structural engineers need to understand basic structural theory and its development. This understanding both ensures that we realise the limitations in our analytical abilities and enables us to validate computer output effectively.

Structural dynamics is the study of how structures respond to loads that vary rapidly with time. This introduction to the subject, focusing on linear elastic structures, explains how to calculate or estimate the key dynamic properties of simple structures, and outlines the principles used by finite element programs in analysing the dynamics of more complex structures.

This text is an introduction to the most important aspects of flexure in structures. A description of the widespread use of flexural elements and structures is followed by an introduction to the modelling and analysis of beams, slabs and frames. The text then discusses the use of four common structural materials in flexural elements and structures.
