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:

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.
