Why do tall buildings have a steel skeleton?

What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why do tall buildings have a steel skeleton?

The Big Idea

A skyscraper has a skeleton, just like you! But it is made of steel. Let's see why steel is so important.

The Frame

Step one: The Frame. A skyscraper's strength comes from a frame of steel columns and beams. It works like a skeleton.

Carrying Weight

Step two: Carrying Weight. The frame carries the weight of the floors, walls, and people down to the foundation. Every piece has a job.

Bending

Step three: Bending. Steel is strong and can bend a little without breaking, which helps in wind. The walls hang from the frame, so they can be thin and light.

A Closer Look

Let's take a closer look! Columns stand up tall. Beams go across. Bolts hold them together. The foundation holds it all.

Quick Facts

Quick facts! Steel beams are often fastened with huge bolts or welded together. Steel bends a little in wind. A building's frame is like the bones inside you. Triangle braces make frames stronger.

Think Like a Scientist

Now, think like a scientist! Make a tower out of straws and tape. Make a second tower with diagonal braces. Gently push the top of each one. Which tower stands better? Why do you think braces help?

Outro

Tall buildings have a steel skeleton of columns and beams that carries the weight down to the foundation. Steel is strong and bends a little in wind, so the walls can be thin and light.
