Article Title: A whole new ball game.

Article Author: Stephen Cousins.

Article Publish date: November 2007.

Summary: This article describes a new construction technique known as 'bubbledeck' which is a light weight concrete slab system. It involves the use of air filled plastic bubbles sandwiched between mesh reinforcement before being covered with concrete. This system provides greater strength than a standard in-situ concrete slab and has both cost and time advantages.

Summary: This article provides some advice in relation to the use of pre-cast concrete panels. It suggests that to achieve the maximum benefits from pre-cast panels team members such as the structural engineer and the pre-caster should maintain open communication.

Geelong Carousel- Completed structure

BUILDING: Geelong Carousel Pavilion (Geelong Waterfront).
ARCHITECT: McGlashan Everist Pty Ltd.
ENGINEER: Meindhart (Vic) Pty Ltd.
BUILDER: Wycombe Constructions Pty Ltd.

Geelong Carousel

The above picture shows two diagonal circular sections supporting the carousels cantilevered roof structure. These hollow, cylinder like steel supports have been pressed at either end and pin joined to act as flexible connections.

Tutorial Exercise 3

The following can be seen above.
- Wire safety mesh on both walls and the roof.
- Sinsilation and insulation behind the safety mesh.
- A stanchion (verticle U beam) meeting with an angled beam to form a knee joint.
- Horizontal 'C' girts on the walls to support the outside cladding.
- 'C' purlins on the roof to support the safety mesh, insulation and outer roof.
- Diagonal bracing rods on the left side wall.

Tutorial Exercise 3

This image shows a section drawing of the various elements included in portal frame construction. Note the use of Lysaght 'Kliplok' roofing due to the 2 degree pitch. This type of roof provides greater strength compared to 'Custom Orb' or other corrugated styles.

Tutorial Exercise 1- Completed structure

Building: Barwon Valley Activity Centre (BVAC).
Location: 1 Barwon Heads RD, Belmont Vic.
Year of construction: Unknown.
Builder: Unknown.
Architect: Unknown.

Tutorial Exercise 1

Shown here is diagonal cross bracing in the form of of 20mm rods. These members act in tension, preventing structural failure caused by wind forces and temperature expansion. These struts are used as ties between columns.

Tutorial Exercise 1

Shown in this image is a knee joint whereby a beam intersects with a column tranferring the roof load to the pad footing below. The connections seen here involve the use of stress tested bolts which are fixed into place on site relieving the necessity of welding. Note the absence of haunching and the use of horizontal stiffening plates in the column to prevent bending of the flanges.
