Machine Learning in Civil Engineering - Surrogate Models
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

Machine Learning in Civil Engineering - Sensitivity Analysis
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

A primer on the form and behaviour of gridshell structures
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

Plastic Analysis of Frames – A Complete Guide – Part 2
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

Plastic Analysis and Plastic Collapse – A Complete Guide – Part 1
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

P-Delta Analysis and Geometric Non-linearity
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

The Stress-Strain Curve & Plastic Hinges in Beams (1/2)
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

Yielding, Plastic Deformation and Moment Redistribution in Beams (2/2)
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
