Building Principle Notes (on web)
course objectives● introduce concepts of structure
in architecture
● introduce some simple building structural systems
● introduce the structural use of materials
5/21
course outcomes
● an understanding of the physical properties and behaviour of materials
● an understanding of the forces acting on buildings and the way structures respond to these forces
● the ability to analyse and design simple structural systems
● a familiarity with different simple structural systems
6/21
assessment
● labs & reports x 3 (1 + 2)
● assignment (sem 1)
● work sheets x 8 (sem 2)
MASTERY TASKS
SUMMATIVE
FORMATIVE
7/21
● test (sem 2)
why learn structures?
● not to make you structural engineers
● better designers
● able to communicate with structural engineers
8/21
what’s it all about ?
● preventing gross errors
● making intelligent decisions regarding
● selection of structural system
9/21
● selection & sizing of members
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.

nature of structure a building is a balancing act
human space does not exist until enclosed by structure
enclosure of space
resistance of structure vs
forces of nature
TRUCTUR
S E
function of structure
● to resist all the forces (loads) acting on the building
● to transfer them to supports (the ground)
12/21
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
designing structures
no right answer
larger the enclosed space - more need for structural efficiency
14/21
little skill required to designbuilding which will stand up
