LISUS details



These images are from www.lisus.com.sg the details which i talked about 2 posts previously.  I used these measurements for my model  so if you compare my model measurements to these notes they are similar for certain aspects such as the web diameter and the brackets for concrete connection. However i have made a few changes to the model such as the use of sealant and position of glass panel bracket placements and attachments to the concrete slab. The rest of my measurements for my model i derived from the appropriate Australian Standards which i posted this month aswell. 

( NB/ I am just about to hang in my model and poster so wish me luck that it doesn't get damaged in the process and there is a small amount of wind from the pier)

PROJECT

ok so this is the photo of my poster, read below to find out why its a photo.

i am trying to upload my project poster but is not working so i shall try again at uni. If worst comes to worse i will have to take a picture (not very professional) of it or scan it. night

PROJECT DETAILS

www.lisus.com.sg

I found this website very useful in trying to obtain images and details for annealed glass frames that included a fin and a web connection. This site also had images for connection to cement roofs and slab on ground.

Although at the moment i am having difficulty trying to upload the particular images i obtained so i shall try again tomorrow at university and if that doesn't work then i will provide a direct link to each image which i perceived to be of use. 

Site visit



Date photos taken: 3.06.08
architect: David McCallum
company: DDB design
photos taken by: myself
location: 179 New St Brighton VIC 3186

I visited a site today which had an interesting integration of frames and structural steel. when asked why this was the builder replied that the structural beams were placed in areas where the highest load bearing will occur because the residence also went underground by one level (there was a carpark underneath and a lift shaft had also been constructed. I was unable to get an overall shot as there was a truck in the driveway blocking the overall view (didnt really want to ask them to move :) )

Australian Standards

Below is some information i have gathered by reading a variety of Australian Standards. All the information further collaborates measurements and material selection for my MAJOR PROJECT.

AS 1288-2006

2.1.1

o Tinted heat absorbent glass classified in accordance with AS/NZS 4667

2.1.4

o Safety glazing material complies with the requirements of AS/NZS 2208, they are non-standard thickness. When applied to glazing, safety organic coatings shall extend to the edge of the glass or within 3 mm of the sightline and shall be permanently bonded to the glass.

2.2.2 Structral Sealant

o the structural sealant shall be silicone complying with ASTM C1184. The characteristic strength of the solicone shall be greater than0.21 MPa

  • REFER TO AS 2047 for window walls 
  • 3.3.3 Servicability limit states

    o the maximum deflection for the serviceability states by controlling or limiting deflection.

    2047

  • 3.7.2. Strength limit state

    o the design action effect (except for silicone sealants immersed in water) shall be limited to a max of;

    0.011 MPa for dead and live long-term loads; or

    b. 0.210 MPa for ultimate limit wind loads only

    3.7.3 serviceability limit state

    o b. for but glazing with glass fins, combined joint and frame movements meet the deflection limit requirements of clause 3.5.2.

    o see appendix F for examples

    Plan and elevation for MAJOR ASSIGNMENT


    This is the design my group has come up with. It still needs to be edited on photoshop but essentially i will be using this on my poster. 
    The first image is an elevation of the warehouse west facade. This relates to my detail that i am modeling. I have to finalise the detail i will be modeling but i will later post up a few similar details that i research or find. i will also be reading a few AS that correlate with my detail (that shall be a later post).

    Green Cement- Catalyst

    i watched Catalyst on ABC 22nd May 2008 and a segment was about a new product available called Green.
    'An Australian company has started to make concrete which promises to dramatically cut the carbon dioxide ordinarily emitted during production. Concrete is the second most widely used material on earth, after water. Figures vary, but it's estimated that the manufacture of cement, the reactive ingredient in concrete, is responsible for over 5% of the world's CO2 emissions. 

    Using a technique to make geo-polymers is similar to those found in some natural volcanic rocks, a concrete alternative called E-Crete is now being manufactured in Melbourne , which claims to have reduced the amount of CO2 ordinarilt emitted in the manufacture process by an estimated 80-90%' 
    Quote from Catalyst program (narrator is Graham Phi
    llips) :
    Professor van Deventer: You This is fly ash which comes from the combustion of coal, so coal fired power stations, and we add to that also in this case slag - a waste product from iron making 
    And that is available in abundance through out the world. I’m also putting in some sand just ordinary sand that we use in normal concrete, because that is what we use as a filler.
    Then what we add is just some water and also a little bit of alkaline solution, which turns this mixture of ash and slag and sand into a concrete which will help to bind the particles together.
    Narration: The activator dissolves out aluminium and silicon molecules from the slag and ash.

    These molecules then link together, forming much longer molecules…they’re the geopolymers. 

    The geopolymers themselves link together, creating a vast three dimensional network. That’s what gives the cement its strength. And no carbon dioxide is produced.

    Above is an image fromhttp://www.zeobond.com/ecr.htm. it shows that the E-Crete can support a large load. for the concrete slab you can see the individuals standing next to is E-crete. Very interesting material that Australians invented!!!
