I'm the one on the right by the way.
Welcome to my blog for srt251 Constuction and Structures 2. Feel free to leave any comments.
Really liked the way in which the three different materials
(Glass, wooden board cladding and plaster cladding) are complementing each other in this picture. The joining has being concealed in order to achieve a smooth, clean and striking finish.
Below shows the concrete column – with the joint to the ceiling concealed by the external cladding. It is clear to see the sealant between the two which allows for movement – either contraction or expansion – of the concrete. This movement is dependant on the temperature and the loads imposed on the column.
The picture below shows how the structure is exposed both on the outside and the interior. The steel framing forms the geometric shapes of the windows whilst the steel universal column supporting the roofing structure can be seen on the inside. The aluminum façade to the building casts dramatic shadows during the different stages of the sun movement path.
The detail below shows how a Universal Beam has being engineering to fit the angle of the roof to act as a rafter. Diagonal bracing is incorporated to resist the lateral wind loads. The steel column is attached to the wall via girts which are welded and bolted to cleats.
The Universal Beam here is connected to the ceiling by ‘C’ girts which again are welded and bolted to cleats. This has then being covered by 20mm plasterboard.
I was able to return to the Spotlight Development site located at the Belmont / Breakwater inter-junction in order to meet with the project manager, Chris. This was really insightful into the construction of concrete tilt up panels. I was able to determine that the size of my strip footing for the major project would be 600mm x 600mm with 6-12TM. This was based on similar sized panels framing the structure of the retail blocks which would in turn have similar loads as those in my showroom structure.
The drawings also demonstrate possible ways of connecting the RC Slab on Ground with the wall panel using Cast-In Plates. One of the other details also shows how a suspended slab could be attached to the panel using a dowel and ferrule system – a possible method that could be employed for the major project.
Building With Straw | | |

As long as appropriate moisture control measures are taken, straw bale walls can last as long as any other conventional systems. However overhangs are required in order to keep the rain (if it ever comes) of the walls. These overhangs should be about 45cm and the bales should also be raised 60cm off the foundations to reduce capillary action of ground moisture. Cement is mixed with lime to increase the permable properties and allow the straw to ‘breathe’ and release any moisture. Rebar is also imperative to stop the straw from getting wet and structurally failing. Rebar is a metal used to spike the bales together when fitting them as a wall. Flashing is required at the top of the walls to allow the water to divert the water away from the straw.
