Article 3-Three Dimensional Modelling of Steel Portal Buildings

Mahendran, M & C Moore 1999, Three Dimensional Modelling of Steel Portal Buildings, August Edition, Journal of Structural Engineering.

As this article was from an engineering journal, it included many technical calculations that I didn't need. But despite this it did look at the structure of a steel portal frame. It looked at the cladding, bracing and details of a test portal frame that they constructed. I found the details to be of the most use.

Article 2-LVL

Forest & Wood Products Australia 2007, LVL, Timber.org.au, retrieved 30th May 2008, http://www.timber.org.au/NTEP/menu.asp?id=103#LVL_beams

This article looks at the material Laminated Veneer Lumber, or LVL. It looked at its manufacture, typical uses andproperties. It helped me to understand why LVL is used in Timber Portal Frame Construction.

Article 1: St Andrews Anglican Church - Timber Portal Frame

The church is a timber portal frame building using LVL box beams. The church was designed by Innovarchi Architects, and the structural engineers were Timberbuilt, and Reinhold and Stanaway. The church is located in Barry Street, Gracemere, Central Queensland and was constructed in 1995.

The article provided an overview of the construction technique used (timber portal frame). It looked at the materials used in this particular project, the type of joints that occur in a timber portal frame as well as the design features of the church.

Tutorial 6

Above: Typical two storey office block section taken between columns.

This section shows the use of composite construction, which is a form of construction where two materials combine, taking the beneficial qualities from both materials. E.g. Steel and Concrete; tensile strength taken from steel and compressive strength taken from concrete.

Tutorial 5

ABOVE: Tutorial Exercise-Week 5

The above tutorial exercise is of concrete construction using pre-cast concrete panels. The difference between this tutorial exercise and the previous one, is that insulation has not been used in this tutorial exerise and in the previous tutorial exercise the concrete floor slab is non-structural, whereas in this weeks tutorial exercise, a combination of a reinforced concrete slab and an infil slab make the concrete floor slab structural.

Tutorial 4

ABOVE: Tutorial Exercise-Week 4

This tutorial exercise looks at concrete construction, using pre-cast concrete walls.

Bendigo Market Place Extension Construction Site-Visit 1 (24/03/08)

ABOVE: Photo of Bendigo Market Place Extension showing both existing structure and extension. Also shows steel 'parallel chord' truss, steel portal frame and pre-cast concrete panelling.

ABOVE: Photo of connection between portal frame and loadbearing pre-cast concrete panels

The photo's above were taken of the Bendigo Market Place Extension showing a steel portal frame. The extension also uses other construction methods along with the steel portal frame. The extension consists of two floors, while the existing structure only has one floor. The below ground floor of the extension will be an underground carpark that uses concrete construction. The ground floor, which is at the same level as and connected to the existing structure, uses loadbearing pre-cast concrete panelling, reinforced concrete slab floor, steel frame and steel 'parallel chord' trusses.



NOTE: The photo's were taken on the 24th March 2008, at Bendigo Market Place, 23-25 Mitchell Street, Bendigo.

Above: Photo of Knee Joint in a steel portal frame of Bunnings Warehouse. This photo shows haunching, UB beam, UB stanchion, diagonal bracing, services going through stanchion, safety mesh and bolted connections.

Commercial Structure Photo's

IMAGE 2: Intersting Element inside Bunnings Warehouse. Joint of universal beams attached to apex of roof, with no vertical support post beneath apex.

IMAGE 3: Detail inside Bunnings Warehouse. Joint of universal beams attached to roof, with vertical support post under apex, also shows bolt fixings.

The commercial building I chose to photograph was Bunnings Warehouse. I chose this building as it clearly shows the portal frame structure of the building. The overall picture (image 1) shows the long span of the building, made possible by the use of the portal frame. The interesting element (image 2) I chose to photograph was the universal beams attached to the roof, that didn’t have a support post under the apex. This is quite different to most of the other apex joints as they mostly have a post under the apex to help support the roof, as seen in image 3.

Note: Photo's used are from Bunnings Warehouse, 237 Colac Rd, Waurn Ponds.
