Had a great Semester. Have learnt a lot and enjoyed the process. Site visits have been an enormous help to me - they've made the theory instantly understandable . The major project (though a tad stressful at times!) was also a great learning tool. Signing out. Victoria


I choose the Pompidou Centre as my inspiration for the Major Project because of its amazing exoskeletal structure incorporating the use of gerber beams or "gerberettes" which allow for a flexible and unobstructed interior - excellent for warehouses. The trusses are loaded onto these huge gerber arms which transfer the bending moments via tension rods to the footings. This allows for greater span of the trusses and a interior freed of supporting columns.
An equally important reason for choosing the Pompidou was that it was designed by two Pritzker prizewiners! Richard Rogers won the Pritzker this year and Renzo Piano in 1998. They worked in partnership at the time of the Pompidou in the 70's.


I have included this link because I followed this project with interest when it was being built (before this semester) . The contruction used to save the tree was screw pile footing . The 100mm diameter screw piles were driven down between the roots with minimal damage to the tree. The tree was cut back quite severely but now is back in full bloom. This tree would not have been saved if a more regular footing system was used.


Pompidou Centre - inspiration for the Major Project

5m x 1om detail of north west corner of the warehouse

Gerberette through wall plate and connected to truss. It acts as a cantilever beam and the outer tension column pulls it downwards reducing the bending moments on the truss top chord .Beneath the gerberette is a vertical support truss for the concrete panels.

Floor plans (if you can see them!

Interconnecting courtyard between office and warehouse (glass cube with a pool wrapping around the end column.)

Free internal space resulting from external steel structural frame.


cute shack for the backyard

After studying materials forhot humid climate forDesign we found termites are a huge issue in this climatic zone. When researching for the assignment I found this cute shack or granny flat that uses termite resistant hybeam joists and hyspan members, allowing bearers and posts to be quite close to theground.These products put out by futurebuild also allow greater span and fewer steel posts and small buildings like this outhouse can be simply unbolted and taken away ('when granny dies" !)

Good environmental product - Boardwalk decking with no in ground footings

Part our our research for Domus included boardwalks between pods. A new product by Rocla called permatrak offers a cost and ease of installation solution to installing decking when access to skilled workers is problematic. They can be considered as an environmental product as low impact during construction and in ground footings are unneccesary. Supposedly minimal physical impact protects ecologically sensitive sites. Hmmn... i wonder. Could be a lot of hype. Sorry no image. Wouldn't upload.

Egg cartons in beachshack!- Luxalon Quadroclad

Asked a builder friend about what new products were particularly impressive in the building industry and he was about to investigate this product as he felt it had potential as a lightweight product for large surfaces although cost was going to be an issue. The honeycomb structure is very similar to the egg carton insulation we found in the walls of our beachhouse when we were renovating!

this concerns me

We researched ironwood for Design 2A 'Domus' hot humid climate brief (Kakadu)' and concluded that ironwood was a sustainable plantation material. Reading this article, I now begin to question this. This suggests that ironwood is hard to find and that consumers have driven the need to source it from anywhere!

An exhibition on at Fed Square. Will try to get to it this weekend.

colorbond product.

I have included this article on my blog as Aramax is a recent roofing product that
has a deep profile and is able to span up to 20 metres. Good for warehouses maybe.

con assignment in progress

Exterior of warehouse with exoskeletal structure
Inside of warehouse - no structure!

View of truss which is loaded on the "gerberette" or gerber arm which pivots at the column and is attached at the other end to a tension column which transfers the forces out and down to the footings - all of which reduces the bending moments on the truss thus allowing for a greater span and less depth to the truss thus freeingup of internal space. Celebrating the structure includes notonly an exoskeletal steel strucure but also exposing the concrete pad footing. CHS column with steel arm which has dual function of supporting concrete panel and the horizontal and diagonal bracing.

Safety mesh on.
The dunny!

Safety scaffolding up for next stage.

These massive 9 x3 metre concrete slabs are cladding only and are connected to the columns only by the teeniest weeny spring clips that are 150mm x 70mm in size.(shown in last site visit). Very hard to wrap my head around this.

Hoping that the infill slab would be down but not yet. Gravel bed is ready.
