Introduction

A bit about me....

Do you know what a civil engineer is?

What do you need to do that?

• To be good at Maths and Science• To have Maths and Science Qualifications• Either go to university or….• Do a modern apprenticeship• To enjoy problem solving• To want an exciting career!

So, what do I

actually do??

A quick look at bridge engineering…

From the wooden suspension bridge…

…to the vision of architecture and engineering combined

Tension = being stretched

Compression = being squashed

Some engineering principles

In a triangle:

in compressionin compression

The corners are trying to slide apart, so the bottom of the triangle

is in tension

In a truss- •Tension is blue •Compression is red

Materials:

•Some are better in tension than in compression (think about an elastic band)

•Some are the other way around (like stone and concrete)

•You will have to experiment.
