Forces on Structures

Have you ever wondered how buildings cope with the forces that hit them?

We have been learning about natural disasters and looked at how architects use shapes to help create stronger structures. We learned that rectangles are not good shapes for structures and that triangles are used a lot to make a building stronger. We also learned how the arc of a bridge spreads the weight across the bridge making it stronger than a rectangular flat bridge. We tried some experiments with playing cards to see if we could build structures. It was impossible with rectangular structures but some of us managed to make triangular structures.
