Massive Structure

4.1. Massive structures and lintels The first man-made structures were carved from rock or were built by stacking 3 rocks or other materials. This left little space between them, like in the Mayan or Egyptian pyramids. Short stone or wooden lintels! were also used to make windows and open spaces, for example, in Greek temples.

Vaulted structure

4.2. Vaulted structures With arches and vaults, builders could cover larger spaces and have bigger gaps in the structures. Vaulted structures are formed by arches and vaults using stones that are cut in such a way that the only stress they support is compression - no problem for hard stone. The Romans used round arches to build bridges and aqueducts and they used barrel vaults and domes to cover basilicas and pantheons. Later, pointed arches and ribbed vaults were used in mosques and cathedrals. We still use them today.

Suspended Structures

4.4. Suspended structures This type of structure uses cables, called suspenders which the structure hangs from. When they can be adjusted, they are called tension members. The cables only bear traction stress, but the advantage is that they can adapt their shape to different loads at different times and they are incredibly light. Cables are used to fasten bridges, marquees, antennas and towers. There are many kinds of suspended structures which can cover large spaces like stadiums and pavilions, without the need for columns or pillars.

Triangular Structure

4.3. Triangular structures These structures are made from bars, normally metal or wooden. The use of triangular shapes means they are not easily deformed. This makes them ideal for building bridges (triangular beams), covered with large trusses'5 and vertical structures, like towers and scaffolds'.

Laminated Structure

4.6. Laminated structures These are formed by laminates of metal, plastic or composite material like reinforced concrete. Their curved shape and folds give them their strength. I The curved shape makes the laminates bear the stress of traction and compression on their surface. I The folds and ribs? give rigidity in exact points. So, for example, the rim on a plastic cup prevents the cup from deforming when we drink and the grooves on the side make it stronger when we hold it.
