Okay kiddo, do you know what a building is? Yes? Great! A long, long time ago, people used to build with things like wood and stone. They didn't know much about how to make buildings strong, so sometimes they would fall down or break.
Then, people started to realize that they needed to learn more about making buildings sturdy and safe. This is called structural engineering. They started using math and science to figure out how to design buildings that wouldn't fall down or break.
As time went on, people got better and better at structural engineering. They came up with new materials to build with, like steel and concrete. They also figured out new ways to design buildings, like using arches and domes.
Structural engineering has played a big role in many important buildings throughout history. For example, the Romans used structural engineering to build things like aqueducts and colosseums. Later on, the Eiffel Tower in France was built using advanced structural engineering.
Today, structural engineering is a very important field. People use it to design all kinds of buildings and structures, from skyscrapers to bridges to stadiums. By learning and improving on the methods of the past, structural engineers have made our buildings stronger and safer than ever before.
