HUB / NON-LINEAR ANALYSIS

In this tutorial, we continue to acquaint ourselves with the basics of machine learning by learning how to design specific function approximators called surrogate models. Traditional numerical analysi...more

In this tutorial, we'll dive into the world of machine learning and structural optimisation by focusing on sensitivity analysis as our first topic. We'll start by learning how to define a simple optim...more

In this article, we’ll begin our exploration of gridshell structures. Our overall aim is to build up step-by-step, an appreciation for these elegant structures and their contribution to the built envi...more

In the second part of this series on plastic collapse analysis, we explore how what we learned in part one can be applied the frames. Plastic analysis methods are particularly useful in the analysis o...more

Often in structural analysis, linear-elastic analysis is used, predicting failure when structural members reach their yield stress. This method, while effective, ignores the plasticity that some struc...more

In this tutorial, we'll explore the P-Delta effect; a form of non-linear behaviour that can lead to large magnitude sway deflections in columns. Put simply, P-Delta describes the phenomenon whereby an...more

So why is plastic behaviour so important to understand? It’s probably fair to say that most of our engineering analysis assumes linearly elastic behaviour. But in reality, if we limit our designs to p...more

In this tutorial, we’re going to work out exactly how to determine the plastic moment capacity of a cross-section. We’ll also explore the concept of moment redistribution with an illustrative example....more
