01_Studio Report Activity ‘IN DETAIL’ (PART TWO) To develop an understanding of the actual size of construction elements and the detailed relationship of individual parts.

To experiment with the implications and difficulty of translating a scale drawing to a full size drawing (or a real part of construction).

The line in dark colour is the expansions joint which is also the compression joint.

The weep hole allows the water vapour come out from the inside. The concrete is light and shrink. As they would crack at the corner of the column, the mortar is used for connecting each other.

The gap between the timber flooring is for letting the water sink through to the foundation soil.

The outside timber bend was constructed concrete underside to get water through the gap.

Pin Joints

As the wall was built by the builders at the first place, the window framework was manufactured by Viridian Company at the manufactory. When the window frame was installed into the under-construction site, the window and the wall didn’t match. Therefore, the engineers and the project manager might decide to cut part of the wall to fit the window and use the soldier chord to match the length of the upper bricks. As the steel was 6mm height, they had trouble to cut it so that instead, they cut the bricks. As shown in the photo underneath, a part of the platform under the wall frame was cut by some heavy metal tools. And the edge of the wall are broken. This is a ‘bad detail’ in reality.

Solider Chord

I redraw the gap in A1 paper which has the same depth in reality. The real depth is half shorter than that in the architectural drawing. Therefore, we assume that the final decision can be changed based on objective elements.

GAP between the timber board and the double glazing window

The bolted connection occurred outside and inside, they are recognized as pin joints.

Flashing

The water strip pass the second one which is down to the lowest one directly due to the groove.

The glassed are polluted because of the different window frame and flashing.

The curtain wall of Wilson Hall has thick steel structure on the front side in one direction. The others are thinner on the other direction, and the retaining wall is set at the end. There are spaces of the bottom of the frame, the frame are two structural elements, vertical and horizontal. As the structure need to be balanced, there are 4 thick aluminium beams carrying loads of columns in order to reduce the compressive loads on the bottom.

Such structure is to carry the load, they catch element in the front to the structure behind, and the design of the bottom sill frame is under pressure. As the first generation of the curtain wall was very old, the glass was not very strong and flexible. The previous one was not measured the air and wind pressure so that the glassed are lead to fall out due to the compressive load.

D Repairable surfaces & Resistance to damage

Construction Detailing E-learning, 2014 A Movement Joints

Slating

->considered as valid movement e.g. soil movement->contraction and expansion B Health & Safety -Danger- Fire -Using stairs are safer -Australian code limits the materials selection. The material selected based on the risk of the fire.

C Age Gracefully -As some buildings deteriorate quite quickly with water staining or water damage - Material Selection –>reduce material age ->deteriorate in harsh environment in sea site with high salt level or polluted area.

- Other material improve the appeal of age (copper/timber->grey, attractive as long as the grey painted evenly)

Can be replaces A bit of movement between the walls E Constructability (Considerations) - Possible to adjust inaccurate mistake -Off the shelf items (if manufactured, not designing it) -Detailing to suit construction expertise (Excellent overseas-> expensive, but consider fitting the local needs)

E Cleanable Surfaces

Butt Cove for resilient Building

Straight base for carpeted floor

Top set cove for any flooring type

Cove & Cap strips

Composite Materials Main Types -Fibrous (products containing discontinuous or continuous fibres) Fibre Reinforced Cement (FRC)/ Fibre Glass) -Laminar (sandwich panels) Aluminium sheet composites -Particulate (gravel and resins) - Hybrid (combination of two or more composite types) Fibre Reinforced Polymers (FRP) -Commonly used in decking (external cladding), structural elements such as beams and columns for public pedestrian bridges -High strength FRP materials with glass or carbon fibre reinforcements provide a strength to weight ratio greater than steel.

-Wood, metal or vinyl base’s require to conceal & finish the joist at the floor->prevent quick damage form foot damage vacuum cleaners

Patched over before the building finishes Gap- Cover strip in place

Composite Materials E-learning, 2014 (Glass, rubber, plastic, brick, concrete, timber) 1. Monolithic material -Single material -materials combined so that components are indistinguishable (e.g. metal alloys) 2. Composite material -created when two or more materials are combined in such a way that individual material remain easily distinguishable What are Composite Materials?

Formed from a: 1. Combination of materials which differ in composition or form 2. Retain their identities and properties 3. Remain bonded together 4. Act together to provide improved specific or synergistic characteristics not obtainable by any of the original components acting alone.

Joints & Connections Ching, 2014

03_Glossary Appendix 1. Sandwich Panel- for building applications, it is the large prefabricated building products. It is a structural panel consisting of two outer metal sheets (steel, aluminium, other) with a stabilizing core of insulation sandwiched between them. The metal sheets are bonded to the insulation core with specialised adhesives. The outer surface of the sheets can be flat, slightly corrugated or with a large profile (e.g. for roofs or external faรงade design). A huge assortment of shapes, coatings and colours is available. Because sandwich panel installation requires only a limited number of mechanical fasteners (e.g. screws), the resulting constructions avoid significant thermal bridging. To achieve distinctive architectural features, panels with hidden joints are available (Rockwool Core Solutions, n.d.).

2. Composite Beam- a Steel Beam, which has concrete decking above it, and which is connected to the concrete by shear connectors, which can cause the steel and the concrete to act together. Generally the steel can carry the wet weight of the concrete, but when this has set, the two materials will share the load, the concrete mostly acting in compression (REID steel, n.d.).

- Frequently used in Composite Steel Bridge System

3. Bending- the bending effect at any section of a beam. The bending moment is equal to the algebraic sum of the moments taken about the cross section.

4. Shadow line Joint- it acts as reveals, and shadow lines. The darker siding is a powerful gesture, but the joinery is less pronounced because the shadows on the dark surfaces.

5. Skirting- the moulding covering the joint formed by a wall and the floor.

Can be referred to the Construction Elements  

Baseboards Moulding (decorative)

6. Cornice- the horizontal moulded projection that crowns or completes a building or wall or it is the moulding at the top of the walls of the room, between the walls and ceiling.
