Week 8 Studio Journal
ENVS10003
This week’s studio consisted of a 1 hour workshop and a detail drawing session. Activity 1: Workshop Although I was unable to attend the workshop, I understand that the task was for three groups to construct timber structures using three different methods and to test which method of construction could withstand the most force.

Timber measurements:
- 1200 x 3.2 x 90 mm Ply
- 1200 x 3.2 x 90 mm Ply
- 1200 x 42 x 18 mm Pine
- 1200 x 35 x 35 mm Pine
Structure:
Structure:
- Truss using zigzag web as opposed to
- Two 1200mm parallel pine members were connected to evenly spaced perpendicular pine studs using nails. See Figure 1. - This structure would have effectively resisted compression as the force is transferred evenly across the studs. The closer the studs are spaced,
perpendicular studs between the horizontal pine members. See Figure 3. - For a truss system to be effective against axial compression, the zigzag axes and load at a joint should pass through a common point (Ching, 2008). See Figure 4.
the higher the load the structure is able to resist (Ching, 2008). See Figure 2.

Figure 4 Group 3 Timber measurements: - 1200 x 3.2 x 90 mm Ply - 1200 x 35 x 35 mm Pine Structure: - Horizontal pine members with plywood sheeting attached at sides. See Figure 5. - The load applied to this structure would be uniformly transferred down onto the long edges of the plywood. See Figure 6. - This simple structure is likely to withstand a fair amount of compressive force. The strength of the plywood is something that is heavily relied upon in this design.

Activity 2: Built detail
References
This task required us to create a 1:1 drawing of a
Ching, D.K 2008, Building Construction Illustrated,
guttering detail from a case study building. The aim
John Wiley & Sons, Inc., Hoboken, New Jersey
was to become familiar with how components are represented in architectural drawings, as well as to better understand the function of guttering. I chose to draw a detail from the Oval Pavilion Site, shown in Figure 7.
Figure 7 Main components (Ching, 2008): - Aluminium flashing: prevents the entrance of water into the internal building structure by directing the movement of water using gravity. Various flashing methods are used to prevent water entrance, including the overlapping of materials, the use of air gaps to disrupt capillary movement and the use of drips to break surface tension. - Thermal insulation: controls the transfer of heat into and out of the building interior. - Brick veneer: non-structural cladding. - Corrugated iron gutter: directs the flow of water off the roof.
