Essential Knowledge Text No.9 Stress and strain

This is an introduction to the most important aspects of triangulated structures. Triangulated structures are widely used and can provide stiffness with very little structural material. Being formed from many interconnecting parts, a knowledge of several aspects of modelling, analysis and design is needed to be able to understand their structural behaviour.

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.

A summary of the ground engineering knowledge required of all structural engineers. Only core concepts are introduced, supported by the most important theoretical background.
