Model Photos

Here are some photos of my detail model for the major project.
It is the connection between a steel rafter and a loadbearing concrete panel, while also showing the roof structure and the box gutter.

Here are some Engineering Drawings that I obtained from an engineer that relates to my project.

The Greenhouse Effect

Here is an article on Australia's Greenhouse gas emissions. An interesting figure to note that nearly 69% of Australia's Greenhouse is producing by human activities

The Greenhouse Effect.

Greenhouse gases are a natural part of the atmosphere. They trap the sun's warmth, and maintain the earth's surface temperature at a level necessary to support life. Human actions are increasing the concentrations of these gases in the atmosphere, creating the prospect of global climate change.

Water vapour is the most important greenhouse gas, but human activities make little direct impact on the amount of water in the atmosphere. Human activities have a significant effect on carbon dioxide that comprises 68.4% of Australian Greenhouse gas emissions, methane comprising 25% and nitrous oxide, 6.4%.

Australia’s net greenhouse gas emissions for 1999 were 458.2 million tonnes of carbon dioxide equivalents, excluding land clearing. Land clearing is accounted for separately due to high levels of uncertainty associated with the estimates. Emissions from land clearing are a result of burning cleared vegetation, decay of unburnt vegetation and from soil disturbance which are offset by carbon sequestration due to regrowth of vegetation on previously cleared land. It was estimated that net emissions from land clearing were 71.7 million tonnes of carbon dioxide in 1999.

Carbon dioxide emissions resulting from direct human activities have significantly altered the global carbon cycle. Carbon dioxide is major type of greenhouse gas released in Australia. In 1999 some 313.5 million tonnes were released of which 256.9 million tonnes resulted from the creation of energy. Electricity generation alone contributed 171.2 million tonnes, with transport the next largest source with 69.5 million tonnes.

Methane makes the next biggest contribution to greenhouse gases. Of the 114.4 million tonnes of methane emitted, agriculture contributed 61.6% of this.

Of the 29.3 million tonne of carbon dioxide equivalents of nitrous oxide emitted, the majority of these emissions were from agricultural soils due to adding fertiliser or burning savannas.

Forest growth provided a CO2 sink of 75.8 Mt, more than offsetting 52.8 Mt emissions from harvesting.

Steel Framing Article

This is an article that I came across from 'Master Builder' magazine Feb/Mar 2007 Volume 61.
The article relates to steel as an alternative to timber framing in housing. The use of steel framing construction in housing is on the increase in Victoria due to the many advantages it has over timber. The advantages are durability, protection against termites and ease of construction.

Timber Framing

The warehouse that I am studying for the major assignment utilised timber framing for the construction of a mezzanine floor office area with a tearoom and a toilet underneath.

Basic timber framing with 90 x 35 F5 pine studs, top and bottom plates and noggings.

The floor framing on the mezzanine floor consisted of 250 x 50 F7 floor joists at 450 maximum centres with 25 mm thick sturctural flooring.

The timber joists of the mezzanine floor are fixed to the steel beam by vertical steel member called cleats with bolts.

The end floor bearer is supportied by a steel angle which is dynabolted to the concrete panel.

The timber stair for the first floor office area is a prefabricated unit that is delievered to site as pictured above. The company that manufacturers these stair units in Stair Lock.

Portal Frame Building

This building is a portal frame school gym located in Melton. The building is comprised of a combination of different materials such as precast concrete panels, brickwork and a sheet metal material.
The floor of the gym consists of structural steel members acting as bearers and floor joists, with timber floor boards.

The portal frame of the gym is expressed externally, with the use of pre cast concrete panels as the cladding at the base of the wall, and a steel sheet cladding at the top of the wall.
The image also shows diagonal cross bracing for the portal frame, and the downpipes from the box gutter connected to steel columns and into the concrete pad footings.

This image above shows the rigid base connection between a steel column and a concrete pad footing. The steel column is also connected to the concrete panel through a bolted cleat shown in the image.
An interesting element of this connection is that the pad footing is raised out of the ground, when usually pad footings are positioned below ground.
