ELI5: Explain Like I'm 5

Structural engineering

Structural engineering is like building a house. Before you can build a house, you need to know how to make sure it's strong enough to stand up to things like wind and rain and earthquakes. That's the job of a structural engineer. A structural engineer looks at things like the shape of the house and the materials used to make it and decides how it should be built to make sure it's strong. They make sure that the foundation, walls, and roof are well built and that everything is put together properly so it will stay strong and safe.
