Structural Requirements for Buildings: Understanding Elements and Materials in Construction

DESCRIPTION

This lecture covers essential structural requirements for buildings, focusing on structural elements and materials used in construction. It explores the nature of structures as load-bearing components, the various materials like steel and concrete, and their essential properties such as tensile and compressive strength. The course also examines real-world examples of innovative structural forms inspired by nature, like the Eden Project and Leaf House. Additionally, it addresses loads acting on structures, stress types, and quality testing of materials. Students will engage in group discussions and case studies for practical insights.

  1. FBE04 BUILDING CONSTRUCTION AND MATERIALS Structural requirements for buildings Wong ChearChing chearching@gmail.com

  2. Lecture outline • Introduction • Structural elements • Building Materials

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

  4. Structures can take different forms

  5. Structural forms – Man-made

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

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

  8. designer Each structural form must have a ..............

  9. 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.

  10. Structural elements in a building

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

  12. Properties of structural materials Tensile strength Compressive strength

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

  14. Tensile strength

  15. Stiffness

  16. Loads Dead loads Live loads

  17. Loads acting on structural elements

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

  19. Applying load generates stress

  20. The structural frame may sway when subjected to wind

  21. Temporary works approval

  22. London's Millennium Bridge Can structures move?

  23. Earthquakes

  24. Summary • Structural elements • Materials • Properties • Behaviour

  25. Suggested references

  26. Quiz

  27. 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).

  28. 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).
