Structural elements
Beams, columns, slabs, walls and foundations each carry specific load types.
In depth
Beams carry bending and shear, columns carry compression and bending, slabs span between supports, walls carry gravity and lateral load, footings spread load into ground, and bracing or shear walls resist lateral forces. Each element is idealised for analysis.
Key points
- One-way vs two-way slabs
- Shear walls and cores
- Connections matter
ExampleA typical building frame consists of columns, beams and slabs.
What is Structural elements?
Beams, columns, slabs, walls and foundations each carry specific load types.
Why is it important to understand structural elements?
Each structural element has a specific role, so knowing what it carries tells you how to detail and check it.
What is the difference between a beam and a column?
A beam mainly resists bending and transfers load sideways, while a column mainly resists axial compression and carries load down.
Which elements are usually in compression?
Columns, walls and piers are the common compression members, while cables and ties resist tension.
How is Structural elements used in practice?
Typical applications include identifying which members resist bending in a floor system, choosing a column size for a multi-storey car park and deciding where a wall must carry load and where it only divides rooms.
What should I learn before Structural elements?
Study "Load paths" first (topic 3 of 112 in Civil & Structural). It covers the groundwork this topic builds on.
What are the key points of Structural elements?
One-way vs two-way slabs. Shear walls and cores. Connections matter.
Can you give an example of Structural elements?
A typical building frame consists of columns, beams and slabs.
What comes after Structural elements?
The next topic is "Types of structures", which builds directly on this one.
How difficult is Structural elements?
It is classed as Beginner in Civil & Structural (topic 4 of 112). It is an entry-level topic. It relies only on basic school mathematics and the ideas introduced earlier in this discipline.
