Structural Analysis Fundamentals
How structures carry load, and how to work out what is happening inside them.
A guided course that takes you from looking at a structure and seeing a physical object, to being able to model it, find the forces inside it, and judge whether the answer makes sense. It is built around explanation and practice rather than pages of notes: you predict, try, get it wrong, and find out why. Key results are derived from first principles rather than quoted.
Who it is for
- Civil and structural engineering students in their first or second year
- Graduates revising core mechanics
- Engineers preparing for technical interviews
- Engineers coming back to structural analysis after time away
- Engineers from other civil disciplines who want to understand how structures behave
What you should already know
- Comfortable with basic algebra and rearranging a formula
- Trigonometry: sine, cosine and right-angled triangles
- Some calculus helps for the derivations, but each step is explained
- No previous structural analysis is assumed
How it works
Each lesson explains one idea at a time and asks you to predict what will happen before showing you. Worked examples reveal themselves a step at a time, so you can try the next move yourself. Practice questions check the number you typed rather than the words, and give a staged hint before they give the answer.
How long it takes depends on how much you already know. The syllabus runs to 18 modules in four stages, all of them written: 72 lessons with 13 full derivations, 72 worked examples, 24 interactive tools and 303 practice questions. Every number quoted in every lesson is recomputed by the test suite from the same calculation library the interactive tools use.
The syllabus
Four stages. You do not have to start at the beginning — each module lists what it assumes, so you can enter wherever suits you.
Structural foundations
6 of 6 written- 01Open →
Structures, modelling and idealisation
What a structure has to do, the forms engineers use, and how a real structure becomes a model you can analyse.
- 02Open →
Forces, moments and equilibrium
Forces as vectors, turning effects, the three equations of equilibrium, and finding support reactions.
- 03Open →
Internal forces and structural diagrams
What happens inside a member, and how shear force and bending moment vary along it.
Stress, materials and member behaviour
6 of 6 written- 07Open →
Stress and strain
From force to stress, from movement to strain, and the law that links them.
- 08Open →
Engineering materials
What a tensile test actually tells you, how the elastic constants connect, and what happens when load is held for years or repeated for millions of cycles.
- 09Open →
Bending of beams
Why bending stretches one face and squashes the other, and what makes a good section.
- 10Open →
Shear in beams
Deriving τ = VQ/It, why shear stress is zero at the top and bottom faces, and why the web carries the shear.
- 12Open →
Composite beams
Two materials working together: strain compatibility, the modular ratio and the transformed-section method.
Deflection and general stress analysis
3 of 3 written- 13Open →
Beam deflection
How much a beam moves, why that often governs, and how to picture the shape first.
- 14Open →
Complex stress and strain
Stress on any plane through a point, principal stresses, Mohr's circle, strain gauges and when materials yield.
- 15Open →
Virtual work and energy methods
Strain energy, the principle of virtual work, and the unit-load method — one technique that finds the deflection of almost anything.
Advanced structural analysis
3 of 3 written- 16Open →
Statically indeterminate structures
When equilibrium alone is not enough: compatibility, the force method, slope-deflection, moment distribution and the matrix stiffness method.
- 17Open →
Influence lines and moving loads
What happens when the load will not stay still: influence lines, the Müller-Breslau principle, and finding the worst position of a load train.
- 18Open →
Structural instability
Why slender columns fail long before the material runs out of strength.
All eighteen modules are written. The coverage matrix records, section by section, what is covered in full, what is covered more briefly, and the few topics deliberately left out — so you can see the gaps as well as the content.
