  1. Welcome to Design Studies 1A STRUCTURES

  2. who am I ? Mike Rosenman where am I ? Room 279 contact ? Ph: 9351 5933 Fax: 9351 3031 Email: mike@arch.usyd.edu.au http://www.arch.usyd.edu.au/~mike 2/21

  3. web http://www.arch.usyd.edu.au/~mike • BDes Year 1 - Design Studies - Structures • Course Material 3/21

  4. texts Cowan H. J., Gunaratnam D. and Wilson F. (1995). Structural Systems, Dept of Arch and Design Science, University of Sydney Building Principle Notes (on web) 4/21

  5. course objectives • introduce concepts of structure • in architecture • introduce some simple building • structural systems • introduce the structural use of • materials 5/21

  6. course outcomes • an understanding of the forces acting on buildings • and the way structures respond to these forces • an understanding of the physical properties • and behaviour of materials • a familiarity with different simple structural systems • the ability to analyse and design • simple structural systems 6/21

  7. assessment MASTERY TASKS • labs & reports x 3 (1 + 2) FORMATIVE • work sheets x 8 (sem 2) SUMMATIVE • assignment (sem 1) • test (sem 2) 7/21

  8. why learn structures? • not to make you structural engineers • better designers • able to communicate with structural engineers 8/21

  9. what’s it all about ? • preventing gross errors • making intelligent decisions regarding • selection of structural system • selection & sizing of members 9/21

  10. code of Hammurabi 229. If a builder build a house for some one, and does not construct it properly, and the house which he built fall in and kill its owner, then that builder shall be put to death. 230. If it kill the son of the owner the son of that builder shall be put to death. 231. If it kill a slave of the owner, then he shall pay slave for slave to the owner of the house. 232. If it ruin goods, he shall make compensation for all that has been ruined, and inasmuch as he did not construct properly this house which he built and it fell, he shall re- erect the house from his own means. 233. If a builder build a house for some one, even though he has not yet completed it; if then the walls seem toppling, the builder must make the walls solid from his own means.

  11. C U T R U T R S E enclosure of space nature of structure • a building is a balancing act resistance of structure vs forces of nature • human space does not exist until enclosed by structure 11/21

  12. function of structure • to resist all the forces (loads) acting on the building • to transfer them to supports • (the ground) 12/21

  13. 3 main considerations • Stability - equilibrium building must not move - up, sideways or overturn all forces and moments must balance • Strength building must not break / collapse • Stiffness - functionality building must continue to serve its purpose must not deform too much 13/21

  14. no right answer designing structures little skill required to design building which will stand up larger the enclosed space - more need for structural efficiency 14/21

  15. Reading Structure www.structurae.net/structures www.salvadori.org/aoc/ 15/21

  16. http://www.structurae.net/structures W. H. Smith (1980). The world’s Great Architecture, Hamlyn, London Vickers G. (1998). Key Moments in Architecture, Hamlyn, London images from 16/21

  17. why make certain decisions? what is the functionality? why this form? why this system and materials? why these sizes? 17/21

  18. what are we looking at? 18/21

  19. loads & failure 19/21

  20. structural systems 20/21
