IntroductionMelbourne Sports and Aquatic Centre (MSAC) is Australia’s leading sports and recreation facility. With so much to offer under one roof. MSAC Architectural Design required the means of innovation in both design and construction. The Need to create SPACE and Volume, use of traditional beams and columns are to be minimised in design, if not eliminated.

The use of suspension or overhanging roof with a series of truss roof structures, arches and joints connection is employed in the design concept, allowing exploration of light weight materials and a reduction in overall materials use. This represents an innovative construction technology that allows the creation of volume without compromising the integrity of the structure. A section of the MSAC is analysed in this project to demonstrate a variant of innovative construction technology.For More Info Go to :

Structural System

The dead loads transferred in terms oftension are channelled through the metal rods In the direction showed by the arrows to the central column, raft slab footing And finally to the foundation.

Refer to construction system for detailed drawing of section.

Structural System

The central column is braced by four bent steel bars composed around to resist wind loads acting on the column. Metal strips like the one located in the middle of the pole tie the bars in position so bracing against major areas are attained.

Structural SystemBasic Load Variants:

Dead Loads- The forces exerted by the structural components of the building to the supports. In the case of the support column, the dead load would comprise of the weight of the tension rods, column, roof and part of the walls as well.

Live Loads- Refers to any variable force elements like those imposed by occupants, furniture, fixtures and equipment. In the case study, the live loads would comprise predominantly of the swimmers and populace, water body (when the pool is emptied, the water table of the river exerts forces on the structure as well) and machinery like the ripple machine and broadcast system.

Wind Loads- Refers to the force from the wind on the structure. In reference to the case study, the structure is adequately braced to withstand wind loads of a variety of directions and magnitude.

Construction SystemCable Tower

Suspension Bridge Construction

The Tower holds up the Roof Structure using a concept similar to the construction of a suspension bridge. The cable in tension holds the tower in position. The roof is held in place through countering opposite tension in equilibrium. Truss structure in the tower, ensures a reduction in material while providing the strength required, similar to that of a construction crane’s structure.

Tension truss

Roof Bracing

A series of arches supported by tension cables allows compact and minimal use of material to create an extensive truss system. This allows expansive volume to be created overhead. This Roof structure is held up over a greater span without the need of a complex network of beams and columns.

Construction SystemJoint (Between Competition Pool and Lap

Pool)

The structure is held up using cables. A greater deviation in structural movement will be expected. Therefore joints are needed to allow for greater flexibility to cater for such deviation while the structures are either held suspended or tied to the ground.

Construction SystemRoof Construction (Lap

Pool)

A more extensive truss system is used for roof construction over the Lap Pool. This section of the roof is not held up using the suspension method. Therefore truss overhead is used to ensure structural integrity. Roof bracing is also used extensively to further restrict drastic movement which might eventually lead to structural failure. The reduction in overhead volume results in a M&E services, such as Air ducts to run at a lower height. However the arches, truss and bracing system still provide a sense of volume and depth. The roof construction is supported by flexible yet robust joints which transfer the load to the supporting columns.

Construction SystemExternal Supporting

Structure

The supporting columns are further reinforced by buttress system to further distribute the loads. These structures also held up and ensure the integrity of the wall elements. The construction of these supporting structure provided the strength required while maintaining a sense of lightweight ness without the bulk of traditional. • Main Menu

1 Erection of the Main tower. Tower is further secure in position by tension cables

The weight of the truss elements induce tension in the cables. Cables are secure into the ground to counteract the opposing tension forces.

2 The Arches are secure in position onto the Truss Element, which are acting as Ridges. Drastically reduce the weight of the roof element.

3 Supporting columns are erected in position.4 Truss roof structures are connected to the supporting column through flexible connecting joints.5 Roof Bracings are secure in position to the flexible joints to further restrict any lateral movements.6

Envelope SystemEnvelope System

Set on a 6.2 hectare site, the Melbourne Sports & Aquatic Centre contains championship sized swimming pools, basketball, table tennis, badminton and squash courts. The roof was constructed out of BHP Colorbond Steel along with Kliplok curved roof. The building is Australia’s largest integrated sports and leisure complex and over 20,000 Buildex roofing screws were used in its construction. 12g x 45 mm Hex head HiGrip Teks were used because of both their superior quality and performance. These Teks roofing screws also feature ShankGuard and Climaseal 3 coating, and they were also perfectly matched in colour to the BHP Colorbond Steel and Kliplok curved roof. The zinc/aluminium alloy coating on ZINCALUME® steel, plus the oven-baked, prepainted finish on COLORBOND® steel provide superior corrosion resistance for long life.

Roofing System:

As seen in this aerial photograph the Colorbond roof has been colour coded to match the surrounding area of parkland.

Walling System:

The Walls:- Extensive glazing has been used to allow centre users to take in the surrounding parkland while the sporting halls and the Aquatic Centre have been combined around a glazed gallery overlooking outside recreation areas, gardens and Albert Park Lake. The rest of the external cladding is made up of Minesco panels. These consist of 80mm polystyrene covered either side with steel sheeting. The steel doesn’t have a flat finished surface as this allows for any defects in the finish coating of the steel. These panels were also used on the Melbourne Park Tennis Centre. This wall detail shows how all the elements of the construction go to together and where the Minesco panels are attached.

was found on the internet at http://oak.arch.utas.edu.au/projects/aus/328/melsports.html

Each Minesco panel provides a self-flashing crossover joint onall 4 sides. Based on a tongue and groove principle, the jointdetails are waterproof, obviating the need for external siliconesealants. The main benefits during the construction stage are that they offer a complete cladding system, incorporating structuraljointing, corner, flashing and expansion jointing details and includean integrated panel/window system. All these enable on site construction time to be minimised.
