Civil Engineering

Civil engineers play an important role in all our lives.  They are the ones who design and construct structures that all people use, like bridges, dams and public buildings.  They have to consider the materials for their structures, where they are located (with the help of geotechnical engineers, of course!) and how various forces will interact with their structures (like cars crossing it, possible earthquakes, or the overall load on top of it!

3.  Bridge Types and Parts!

1/30/2014

 
As civil engineers, second graders are specifically focusing on one structure this branch of engineering focuses on, and that structure is a bridge.  Bridges come in many shapes and styles.  

There are three distinct bridge types:  beam, arch, and suspension.  Beam bridges are the weakest and are good for spanning short distances.  Suspension bridges provide the most support over long distances, yet are they are more expensive to build.  Each bridge has special parts that help keep the bridge's shape and structure.  Second graders are becoming bridge experts!

    What structures did you see today in Chicago?  Were they public buildings?  Bridges?  Archways?
