Introduction to Structures¶
- It is a set of elements designed to withstand efforts without breaking or deforming.
There are many structures in nature, from the trunk that supports a tree, to our skeleton. All of them support efforts to overcome gravity and in the case of skeletons they also allow movement.
In the technical field, the construction of structures to make houses, boats or vessels is as old as civilization itself. Today the structures can be very complex and allow the construction of buildings, automobiles, airplanes, bridges, high tension towers, dams and a host of devices without which the current world, as we know it, would not exist.
Types of structures¶
Structures can be classified in various ways depending on their origin or their elements.
Depending on its origin:
Structure of a building.
Depending on your elements:
Formed by a large mass of material with hardly any gaps.
Water dam. Pyramid. walls.
Formed by arches and vaults.
Church roof. Roman bridge. Aqueduct. Rome Pantheon.
Formed by bars joined together in triangles.
Construction crane. Eiffel Tower. High voltage tower.
Formed by vertical and horizontal elements.
Building structure. Chairs and tables.
Made up of cables that support loads.
Cableway. Cable-stayed bridge or suspension bridge. Construction crane.
Formed by a sheet or thin wall.
Bowl. Turtle shell. Motorcycle helmet.
Depending on your movement:
They can move or are articulated. They support loads while allowing movement.
Hinged door. Sliding door. Drawbridge. Wheel chair. Crane.
They do not move nor can they be moved.
Bridge. Building. High voltage tower.
List five natural and five man-made structures.
