A structure is the load-carrying part of all natural and man-made forms.

Structures can take different forms

Structural forms – Man-made

Another example of a building inspired by nature Leaf House, Rio de Janeiro, Brazil

Structural forms in nature Eden project, Cornwall A structure inspired by nature

Each structural form must have a designer. . .

The structure is the load-carrying part of a building, which ensures that the building stand safely under its own weight and under the worst conditions of externally applied force.

Structural elements in a building

What are materials used in the construction of structures? Steel Concrete Composite material

Properties of structural materials Tensile strength Compressive strength

How to test the quality of concrete arriving on-site? Compressive strength Workability

Tensile strength

Stiffness

Loads Dead loads Live loads

Loads acting on structural elements

The loads applied create stresses in the structural elements Tensile stress Compressive stress Shear stress

Applying load generates stress

The structural frame may sway when subjected to wind

Temporary works approval

London's Millennium Bridge Can structures move?

Tutorial questions Submission by email Part A • What is the purpose of a structure, and what the three main types of structural ‘stress’ that a building could encounter along with the types of loads that a building will need to accommodate (using examples where appropriate). • How can you test the quality of concrete arriving on-site? • Find a case study for a project design that is inspired by nature. Then, provide a brief description of the project – highlighting the key features of the building along with any energy and resource conservation measures (500 words).

Part B Write a reflective piece on how you worked as a team, e. g. did you nominate a leader? Did the group communicate effectively or some just sat quickly while others dominated? Did you have a consensus on the answer of each question? Then, you need to reflect on how you could improve working as a part of a group the next time you participate in a group activity (500 words).
