Transcript of Week 1&2

WEEK 1

Construction Overview Key idea-----how the design ideas get translated into the built form

Learning ways:

o Experimentation

o Observation

o critique

What is responsible?

1. structural principles----the way that the buildings are supported how loads are

transported to the ground

2. materials

3. cranes & labour

4. basic science & engineering principles (tension compression, bending torsion &

standard construction techniques)

Materials Introduction strength: weak/strong

stiffness: stiff/flexible/stretchy/floppy

shape: mono-dimensional(linear)/bi-dimensional(planar)/tridimensional(volumetric)

material behaviours: isotropic/anisotropic

sustainability & economy

Melbourne’s bluestone (basalt—from volcano) Lane:

wheel ruts

water damage & impact damage from trucks

stiletto heels damage

Flinder Street:

modern bluestone damaged by modern vehicles

Sydney-----sandstone

Perth----clay for bricks & limestone

Basic Structural Forces A FORCE is any influence that produces a change in the shape or movement of a body

Ching ‘Building Construction Illustrated’ – Page 2.11

-Tension forces stretch and elongate the material

When an external load pulls on a structural member, the particles composing the material move

apart and undergo tension.

Lecturer: Clare Newton

-COMPRESSION FORCES produce the opposite effect of a tension force

When an external load pushes on a structural member, the particles of the material compact

together.

Lecturer: Clare Newton

Load Path Diagrams The applied loads have a reaction which means that the whole

structure is stable.

TUTORIAL ACTIVITY—BUILD A TOWER AS TALL AS POSSIBLE

At first, we made a square foundation, leaving a half-brick space between each bricks.

Then, to build a closed tower, we make the square into a circle.

At last, we decided to make a gate, so we put the bricks one by one as close as possible to avoid

the tower being damaged. Not very stable and beautiful is the gate…

SUMMARY: we need to plan well before we build something

because not any time we can succeed by accident like this. We

didn’t mean to turn the square foundation into a circle…only

because we want a closed tower during the constructing.

Therefore, our tower didn’t have a particular style and a beautiful

looking, although we call it abstract by ourselves. Also we didn’t

need to build a gate. A much easier way is just pulling some bricks

out after we build a stable tower.

Week 2

Key terms Structural joint

Stability

Tension

Frame

Bracing

Column

CHING: 02 the building (2.02_2.04)

BUILDING SYSTEM

Structural system

the superstructure-----the vertical extension of a building above the foundation

columns, beams, and loadbearing walls support floor and roof structures

the substructures----the underlying structure forming the foundation of a

building.

Enclosure system

o Shelter interior spaces

o Dampen noise and provide security & privacy

o Doors provide physical access

o Windows provide access to light, air and views

o Interior walls subdivide the interior of a building into spatial units

Mechanical system

The water supply ----human consumption and sanitation

The sewage disposal system

Heating, ventilating and air-conditioning systems

The electrical system

Vertical transportation systems

Fire-fighting systems

Recycling systems

Factors should be taken into consideration

Performance requirements

Aethelic qualities

Regulatory constraints

Economic consideration

Environmental impact

Construction practice

ESD and SELECTING MATERIALS

CONSTUCTION JOINTS

ROLLER JOINTS Transfer loads only in one direction

PIN JOINTS

FIXED JOINTS

STUDIO TASK “FRAME”
