Introduction

Welcome to our final week. Last week we piled on the stress in more ways than one. This week we are going to do it quickly; in other words, we will discuss how dynamic or time-varying loads influence the behaviour of structures. And, the tools designers use to optimise structures to be resilient and to survive extreme or unexpected events. We will touch on unknown unknowns and emergent behaviour; before concluding the design exercise and finishing with a quiz and few farewell comments.
