There are six main types of structures: frame, shell, arch, mix-and-match, mass, and suspension. Frame structures are composed of long elements joined at the ends. Shell structures have a thin outer layer surrounding an empty or filled volume. Arches can be semicircular and were commonly made of stone in Roman times. Mix-and-match structures combine different structural elements. Mass structures are thick and made of clumped materials. Suspension structures hold beams from tall columns using cables.

10. These structures are composed of long elements joined to each other at the ends.

12. That volume can be empty space or can be filled with something that has no structural relevance.

14. In Roman times,they were made of stone.

15. Romans invented it.

18. The structure is normally thick.

19. They can be made by piling up materials into a shape or design.

21. The distance between one column and the next is calld the span.

24. Is some cases the beam can be laid on the column (Held by gravity.)

27. Examples : Nuts and bolts,clamps,friction...
