Week 10- Constructing Environments Journal entry In this weeks tutorial we looked at all of the case study buildings that had been focussed on throughout the semester. We began by discussing the structural and functional aspects of our 3D details that were completed in the previous tutorial, which I will discuss a little later in the journal. The main focus of this week however seemed to be on the Oval pavilion being designed by Cox Architects. We went to the site and looked at the major components of the construction and the function of its members.
1- Existing building
2- Steel frame timber infill
3- Connection between new and old structure
4- Retaining wall and stairs
6-Wooden feature wall
5- Primary structure
Week 10- Constructing Environments Journal entry The first aspect of the site i am looking at is the existing part of the site, which will be refurbished and fixed up forming a major part of the new pavilion.
Aspects of the structure such as the ceramic roof tiles and the wooden slats are slowly being replaced by new materials better suited to the modern look of the new structure. The major form of the house will be maintained. The building is being constructed using copious amounts of steel beams. This shows that the construction is a steel frame construction with timber infill. The advantage of a steel frame is that the components are created to size off site and brought on site ready to be put into place, weight and cost are some of the limitations of steel (Bluesteel homes, 2013).
The timber infill is considered no load bearing in a steel frame construction (Steel construction, 2013). Despite this the timber frame does withstand wind forces as well as its own force as well as that of the cladding (steel construction, 2013)
Week 10- Constructing Environments Journal entry Thinner steel beams act as and aesthetic finish as well as the structural component that will secure the large glass windows that will later be installed.
Insulation still in bags ready to be packed into the spacing of the walls to insulate the structure.
Existing part of the building, this drawing shows the connection between the new and old parts of the structure.
A skylight has been built into the roof of the building to allow natural light to pass into the interior space.
Reinforcing mesh had been used for the retaining wall. The iron reo acts as reinforcement for the insutu concrete that will be pored over it. The reo provides the concrete with tensile strength which alone it is very weak in, it also acts as a mould for the concrete define that shape the concrete will take (Ausreo, 2012)
Concrete stairs have been constructed in front of the pavilion acting as both a way to access the buildings as well as a space to stand and view the games held on the oval.
Week 10- Constructing Environments Journal entry The mains supports and primary structure for the building are large steel I beams that span in segments across the length and with of the structure. They are connected using heavy duty bolts and are able to take a large amount of tensile force making vibration and shear forces easy to support (AISC, 2002) Thinner steel members are used from both aesthetic finish and structural support for the building. Large beams of laminated wood have been connected to the Steel beams to take the down force of the loads through to the concrete slab bellow. This as an interesting choice which aesthetically looks nice but may also have been a more cost affective measure.
The wooden feature wall is a very appealing aesthetic [art of the building. It is extended high up along the face of the ventilation structure, which contains a double-sided fireplace at its base.
The wooden slats are connected using a tongue and groove system locking each piece firmly in place.
Week 10- Constructing Environments Journal entry In class we and around and looked at each of the 3D details that had been drawn by each class member. We had a discussion about each of the details speaking about each structural component and its function in the structure.
There was a wide range of different details that each showed a unique system and purpose. Different types of block work, flashing, timber and steel members were displayed across each detail. Seeing the details as a 3-dimentional structure was extremely helpful in allowing us to better understand and describe how each detail worked and tied into the buildings they were from as a whole.
Week 10- Constructing Environments Journal entry The pavilion is quite a nicely designed building; the mixed use of steel members and exposed wood make the design aesthetically pleasing. Hearing the builders take on the construction and how each aspect of it works was a valuable experience, although he was hard to hear, the things he had to say were very useful in allowing us to understand the function purpose of each member of the construction.
