Major Assignment - Hollow Core Research Update 2

Ok, well here is where I am with the hollow core research so far:

The ground floor will have a poured slab and strip footing system so the research into hollow core planks will only apply to the first floor and roof, columns and bearers. The planks which I want to span the first floor for about 8m (not 15m), according to the span chart provided by www.hollowcore.com.au will need to use 205mm thick hollow core. (link to detailing manual)

I've also found some great details which may assist with understanding how this will all get put together:

- Detail of beam, column, hollow core connection:

Major Assignment- Hollow Core Research Update 1

I looked a little into hollow core products at http://www.hollowcore.com.au/and would like to use hollow core slabs for the floors in the office block on the first floor. I would like to use the product for the walls as well.
For the first floor of the office, I will need to use hollow core that spans over 15m. Below is a drawing of the 400 thick slab that will be used.

Major Assignment- Hollow Core Research

Following the guest lecture on 'Hollow Core' concrete, 15th May, week 10, and the following tutorial, Chris and I have decided to use a hollow core system instead of in-situ concrete for the warehouse and office block.

In the tutorial Stuart showed us a possibility of how the office would look in section, using a corbel. I would like to use a concrete roof system, which I will have to research.

-------------------------------------------------------------

For the warehouse we need to span 50m with minimal columns to break up the space. Thus it has been decided that we will use a steel portal frame roof attached with bolts to the hollow core wall panels.

-------------------------------------------------------------

It has been decided that Chris will do a warehouse section and I will do an office section. I'm kind of interested to see how I can use the hollow core members to make a grid.

Major Assignment - Warehouse Design Update

After meeting up with my partner Chris Tang we got a few sketches together about how we want the office and warehouse to look. We have settled on a gird kind of design with will be carried through on the warhouse with columns with engaged wall panels. Below are some pictures which we have used for inspiration:

Tadao Ando, Art Gallery Complex, Tokyo design, 1977

-----------------------------------------------------------

Tadao Ando, Onishi house, Osaka, 1979
-----------------------------------------------------------

Tadao Ando, Matsumoto House, Wakayama, 1979-80
-----------------------------------------------------------



Tadao Ando, Fuku House, Wakayama, 1979-80
-----------------------------------------------------------

Plan showing a wall extending out from office block to wrap around car park. Also shows a curved wall in the office block with a stairway following and piercing through this wall to the first floor. These kind of details are typical of Tadao Ando. (see images above)

--------------------------------------------------------

Perspective showing how the office block will be a grid

--------------------------------------------------------

Elevation of the office block

--------------------------------------------------------

How the warehouse might be put together. Obviously the columns will be repeated either site. I imagine the columns will be engaged with the wall.


This Thursday Chris and I plan to talk to our tutor Stuart about exactly how we can connect the roof to the warehouse, weather we have to use all concrete or perhaps a steel portal frame roof? Also I need some help understanding how the office grid will work in pre cast concrete, or should we design in situ concrete as Ando would have done. I'm pretty sure that pre cast panels could be made to have the form work tie dots that Ando uses as architectural detail.

Major Assignment- Inspirational Architect

Architect: Tadao Ando, 1995 Laureate of the Pritzker Architecture Prize

----------------------------------------------------------------------------------------------

Short bio and philosophy:
Ando is a Japanese architect based in Osaka. He is entirely self- taught and had no study under a master architect. He developed his understanding of architecture through extensive reading and site visits to actual buildings in study trips to Europe and the United States, during which he kept detailed sketch books.

Ando describes the goal of his architecture- "to endow space with meaning by using the natural elements and varied aspects of everyday life. The forms I've designed have acquired meaning from their relationship to the elements of nature: light and air, indications of the passing of time and the changes in the seasons."

Quote from A. Zabalbeascoa, J.R. Marcos, Tadao Ando : architecture and spirit = arquitectura y espíritu, Gustavo Gili, Barcelona, 1998, p.56.

-----------------------------------------------------------------------------------------------

Building material: in-situ concrete
His primary building material is in-situ concrete which he has refined to an art form. His concrete has been described as 'smooth as silk', a quality which owes much to the high level of carpentry available in Japan to construct wooden form work in projects. The outcome of bolts holding the form work together, Ando's concrete typically has evenly spaced holes in the surface.

Part of my research will require me to read up on the techniques used to build in-situ concrete the way Ando prefers.
