- You’ll be able to use Python to implement the Piecewise Exact Method to model any form of general dynamic loading.
Shear and Moment Diagrams – An Ultimate Guide
Shear force and bending moment diagrams tell us about the underlying state of stress in the structure. Determining shear and moment diagrams is an essential skill for any engineer. Unfortunately it’s probably the one structural analysis skill most students struggle with most. So in this post we’ll give you a thorough introduction to shear forces, bending moments and how to draw shear and moment diagrams. By the end of this post you’ll know a lot more about shear forces and moment moments then when you started.
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. By the end of this post you’ll be able to calculate the plastic moment capacity of any cross-section and understand in detail how moment redistribution occurs in a structure and ultimately how collapse can occur as a result of hinge formation.
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 purely elastic behaviour, we’re leaving a lot of structural capacity untapped. Structures very often have more load carrying capacity than a linearly elastic analysis suggests. In this post we’ll explore this reserve capacity.
Structural Analysis and Stability – Asymmetrically Propped Structures (2/2)
In part two of this tutorial series we’ll consider how to analyse the lateral stability of a multi-storey structure with an asymmetrical arrangement of stabilising elements. Asymmetrically propped structures undergo twisting or rotation about the centre of stiffness in addition to direct lateral translation. We will consider how to determine the additional forces induced by this twisting. Finally we’ll compare our hand analysis results to a simple finite element analysis model.
Structural Analysis and Stability – Symmetrical Structures (1/2)
All structures typically experience some form of lateral loading during their design life. Typical sources of lateral loading include forces due to wind blowing against the structure, hydrostatic forces due to groundwater (acting against basement walls for example) or inertia forces due to ground motion (earthquakes). In this, the first of a two-part series on structural stability, we will introduce common lateral stability schemes before diving into some numerical examples in this and the next post.
Column Buckling: Realistic Buckling Behaviour (3/3)
In this final post in this series on Column Buckling, we’ll look at more realistic buckling behaviour you’re likely to observe in reality. In particular we’ll explore the behaviour of columns subject to eccentric axial load and columns with an initial deformation, i.e. columns that don’t start out straight. It’s important to recognise that for a column with these characteristics, we do not observe the strict mathematical behaviour predicted for perfectly loaded perfectly straight columns

Your Tutor
Hi, I’m Seán, the person behind DegreeTutors.com. I’m a senior lecturer in Structural Engineering in a leading UK university and I’m also a chartered engineer and Fellow of the Higher Education Academy. DegreeTutors is a website designed to support students along the road to obtaining their engineering degree.
As a lecturer, I see first hand the difficulty many students have with structural analysis; from the basics of constructing free body diagrams, right up to complex analysis of statically indeterminate structures. The tutorials and courses on DegreeTutors are designed to help you build these skills and develop the intuition for structural behaviour that all good engineers need.
