Top &Bottom plates • Horizontal elements • Generally made from pine • Sometimes thickened depending on the loading

circumstances Studs • Vertical elements • Generally made from pine • Thickened at openings where structural elements

and joints are most vulnerable Noggings • Horizontal elements • Generally made from pine • In place to support the studs as the studs a long

and flimsy. • Each span of stud the noggings are at different

heights, this makes it easy to fix each nogging with a nail or screw.

Cross & sheet bracing • CB made from cold formed steel • SB generally made from 3mm ply • Braces the frame lateral forces • Good in tension Lintel • Horizontal element above door or window

opening • Generally made from pine • Can be either directly above the window or door

frame or higher up (just below top plate.) Trimmer • Horizontal element forming the bottom side of a

window opening • Generally made from pine

Can also be made from steel

Core filled concrete blocks a load bearing wall often used in stair wells and elevator shafts, may also have reinforcement bars.

Render is the finish used. Chosen for aesthetic purposes.

Air rated concrete blocks are the enclosure system for this building

Furring channel is the connection between cladding and the structure and also allows for insulation.

Timber stud frame is the structural system for this building.

Cross bracing or hoop iron braces the frame from lateral forces.

Insulation & Water proofing therefore weep holes in the concrete cladding are needed somewhere down the bottom so that water doesn’t build up and damage the structure.

1. Marked out grid to scale on cardboard so that there were fixed points to work from. Once a scale grid was formed measurements for structural elements can accurately and easily be taken from these grid lines.

The University of Melbourne Oval Pavilion

Model scale 1:20

Area of the Pavilion that was to be modelled between numerical grid lines 3&5 and alphabetical grid lines B&C. This gives a starting point and shows where to be looking.

Why aren’t these grid lines parallel to the other grid lines?

2. Mark out columns These measurements were taken from the grid lines once the distances were determined from reading the Structural Plan drawings. The Plan drawings show 150 X 100 X 6.0 Rectangular Hollow Sections used for the columns along grid B which the model had blue striped straws to represent this. The columns along grid line C were 300 X 130 Cypress Glulam Posts which were represented by chopsticks in the model. Straw represents

150 X 100 X 6.0 RHS

Chopstick represents TP1 300 X 130 Cypress Glulam Post

3. Super glue was used in the model to show a fixed joint connecting beams to columns. Where an actual fixed joint in the building may be a weld or series of bolts joining the elements. (Welds and bolts were hard to represent in the model.)

4. Reaction force provided by the ground floor in reality. Below the ground floor was the basement and the loads would continue to be transferred through the ground flooring system then the load bearing walls in the basement and continued into the substructure.

• Stud the slim vertical element of Stud framing system.

• Nogging short horizontal element of a stud framing system in place to prevent the studs from buckling.

• Lintel Horizontal element above door or window opening. Can be either directly above the window or door opening or higher up (just below top plate) depending on the loads within a structure.

• Axial load loads along an axis. Loads in a line.

• Buckling when an element is over loaded in compression and buckling is the deformation that occurs.

• Seasoned timber the process of drying timber from its harvested (green) form. Once it is dry it is seasoned.
