Course
Structural Behaviour
Learning to predict how structures respond before calculating them
A drawing-board course in structural judgement. You predict the movement first, explain the physical reason, reveal the connected response, compare it with your own prediction and retry. Numerical analysis appears as confirmation, never as a substitute for understanding.
Who it is for
- Civil and structural engineering students after introductory statics
- Graduates preparing for technical interviews
- Engineers who build, use or review analysis models
- Mentors teaching structural judgement
What you should already know
- Basic force and moment equilibrium
- Recognition of pins, rollers and fixed supports
- No matrix analysis is required for the rebuilt modules
How it works
Each rebuilt module opens with a taught lesson — the method, worked examples and the rules that must always hold — then a separate set of exercises where the answer stays hidden until you commit a reasoned prediction: predict, explain, reveal, compare, correct, retry.
Every diagram, in the lessons and the exercises, is drawn from a real elastic solve, so the correct answer is genuinely correct and each wrong answer is wrong for a stated structural reason. All eighteen modules are complete.
The syllabus
Eighteen modules in four stages. Each rebuilt module is a taught lesson plus a set of exercises; you can enter wherever suits you.
Foundations of behaviour
4 of 4 rebuilt- 01Open →
Structural behaviour as a visual language
Read supports, movement, reactions and internal-force diagrams as one connected description of a response.
- 02Open →
Equilibrium, reactions and load paths
Trace actions to the ground and predict reaction directions from the movement each restraint prevents.
- 03Open →
Stability, mechanisms and determinacy
Find the movement a counting rule misses and separate redundancy from genuine restraint.
- 04Open →
Stiffness, continuity and compatibility
Use relative stiffness and limiting cases to predict how indeterminate structures share action.
Members and frames
5 of 5 rebuilt- 05Open →
Qualitative behaviour of beams
Connect deflected shape, reactions, shear, moment, curvature and the tension face.
- 06Open →
Continuous beams and support changes
Predict hogging, sagging and reaction redistribution when continuity or support movement changes.
- 07Open →
Qualitative behaviour of frames
Predict sway, joint rotation, member curvature and moment transfer in rigid and braced frames.
- 08Open →
Trusses, arches, cables and structural forms
Read axial-force patterns and recognise when geometry follows the load rather than resisting it by bending.
- 09Open →
Three-dimensional behaviour and grids
Recognise torsion, local-axis action and load sharing hidden by a flat or rendered view.
Deformation and classical methods
4 of 4 rebuilt- 10Open →
Virtual work and deformation
Use a unit action as a spotlight on the regions that contribute to a chosen movement.
- 11Open →
The flexibility method
Release redundants, restore compatibility and superpose to recover the response.
- 12Open →
The stiffness method
Restrain degrees of freedom, assemble member actions and recover the response.
- 13Open →
Moment distribution
Balance and carry over joint moments as a physical stiffness-sharing process.
Collapse, movement and judgement
5 of 5 rebuilt- 14Open →
Plastic behaviour and collapse
Follow first yield, redistribution, plastic hinges and complete mechanisms.
- 15Open →
Slab behaviour and yield-line thinking
Read two-way load paths and plausible collapse patterns without turning this into code design.
- 16Open →
Influence lines and moving loads
Predict how a response at one point changes as load moves across the structure.
- 17Open →
Structural modelling and software checking
Diagnose restraints, releases, axes, diaphragms and misleading plots.
- 18Open →
Integrated structural judgement
Complete studies joining load path, stability, movement, actions and model review.
