WK5 – Studio Report The activity for this week’s Studio was to separate into groups and make a scale model of a part of the Oval Pavilion at the University of Melbourne. The groups had to use the A3 construction drawings of the Oval Pavilion, and use a range of different materials to build a scale frame of a certain section of the building.
The materials my group used for the exercise were balsa wood sheets and masking tape. We tried to use glue to join different elements together, but it was not time efTicient and did not give a strong joint.
The part of the building our group had to make, was the Eastern wing of the pavilion, which housed part of the function room and featured a tall feature wall element and Tireplace. The feature wall element is shown in the photo below, and a sketch diagram shows what was to be included in our model.
Our group decided that the easiest way to rec-‐create the frame of this part of the building, would be to split it into two different structural elements. The main pavilion structure, and the feature wall element. These two elements are illustrated in the sketches below.

WK5 – Studio Report Construction of Piece 1 To build Piece 1 (the main Pavilion structure), our group referred to the A3 drawing set and looked at all the main elements of the structure. We decided to use a 1:20 scale, as it was the appropriate scale for the materials that we had. The diagram below shows the construction drawings of our groups site, which can be found in the Oval Pavilion A3 drawings.
From these construction drawings, our group created our own simpliTied drawings to follow for construction. These simpliTied drawings called for a shorter structure length. The length of individual members are also listed below. Vertical member: 200mm Horizontal Member: 500mm
We made three arch frames labeled 1, 2, 3 on the diagram on the right, and then joined them all together using 2 long beams labeled A and B on the diagram. The elements were joined using masking tape, which illustrated the Tixed joints on the actual building. The photo on the right shows the Tinal form of Piece 1. The red arrows in the image show a load path diagram through this structure.

WK5 – Studio Report Construction of Piece 2 Construction of Piece 2 started with again, simplifying the construction drawings we used as reference. The actual elements of this piece were all included in our simpliTied design, but the way that it was joined to Piece 1 differed from the actual Oval Pavilion drawings. Part of Piece 2 is illustrated in the ofTicial drawings shown below.
We constructed 2 side e l e m e n t s w h i c h w e r e supported/strengthened by a truss system. These elements are shown as element A and B in the diagram. These 2 elements were then joined by 4 beams, elements 1, 2, 3 and 4 (2 joining the top and 2 joining the bottom). ENVS10003 Constructing Environments
Raina Shauki 698887 The photograph on the left shows the Tinal construction of 1 side element of Piece 2. The truss system used in this element will be effective in transferring loads down the tall feature wall, and provides strength to the two long vertical members of the element.
Our Tinal model is shown in the photograph on the bottom right hand side of this page. Red arrows show the load path through the completed structure. As all of the joints that we had to deal with in this model were Tixed joints, using masking tape was an effective way of creating these joints in the model. However, masking tape also changed certain angles of joints causing a few lifted legs or crooked elements. Our simpliTied design also didn't’t show the truss system that exists along the member joining Piece 1 to Piece 2.

WK5 – Learning Loop Columns – Vertical structural members designed to transfer axial compressive loads. Slender members which can be classiTied as short or long. • Short – shorter and thicker. Less than 12:1 ratio. • Structurally adequate if load applied doesn’t exceed compressive strength of material. • Becomes shorter when compressive load is applied and fails by crushing (shear) when compressive strength is exceeded. • Long – taller and slimmer. More than 12:1 ratio. • Become unstable/fail by buckling. Structural frames – Concrete, timber, steel. Load bearing walls – Concrete, masonry. Concrete – Load bearing panels provide support for spandrel panels over and link into other elements. Masonry (Reinforced) – Core Tilled hollow concrete blocks. Used as alternative to steel/concrete lintels. Solid masonry – Multiple skins of masonry units joined together with brick (header showing in face of wall) or with metal wall ties in mortar bed. Cavity masonry – 2 skins of masonry. Damp roof course/weep holes. Metal/Timber stud framing – Consists of top/ bottom plates, vertical stands, noggins, cross bracing,, ply bracing. Brick veneer – 1 skin of non structural masonry covering 1 skin of structural frame wall.

Wood à Timber Grain direction determines structural performance of wood. • Strong and stiff parallel to grain • Weak and Tlexible perpendicular to grain.
Engineered Timber: • LVL – Laminated Veneer Lumber • GLULAM • CLT – Cross Laminated Timber • Plywood • MDF • Chipboard/Stand board

WK5 GLOSSARY
Raina Shauki 698887
Stud – An upright timer in the wall of a building to which plaster board is nailed. Nogging – A horizontal piece of wood Tixed to a frame work to strengthen it. Filling in-‐between wall framing (usually timber). Lintel – A horizontal support of timber/steel/concrete/stone across the top of a door or window. Axial Load – Buckling – When structural members undergo folding/bending, and then give way under compressive forces. Seasoned Timber – Wood that has been been dried/had moisture taken out of it. Seasoned timber has 15% of original wood moisture.
