Just a short note to say that Boxing Day is a day of sporting highlights in Australia - as well as a lot of mahem at the sales.

The first day of the third cricket test at the Melbourne Cricket Ground - The "G" - saw a crowd of some 73,000 watch a slow scoring day on a flat pitch. India batting.

Also Boxing Day is the start of the annual Sydney to Hobart classic ocean yacht race.

From a lightweight structures viewpoint we have the extensive roof structures at the cricket. Also the fast sailing machines with their composite lightweight hulls, prestressed tensile rigging, tensioned fabric sails precisely cut to give a form to generate maximum driving force.

In recent years we have twin rudders and canting keels to maximize the functions of these appendages and in doing so further reduce the weight of the boats.

Some of the super-maxis have very large beams to enhance the planning ability and effects of the crew as ballast. 

What an iconic venue in the Kings Domain in Melbourne! And Happy 60th Birthday!! WOW

This is a unique tensile cablenet structure was designed by Barry Patten of the Architectural firm Yuncken Freeman Brothers, Griffiths and Simpson. Engineering was done by Irwin Johnstone.

The venue is named after Sidney Myer, a Russian immigrant who arrived in Melbourne in 1899 and establish Myers. He also started an annual Music for the People with the Melbourne Symphony Orchestra in 1929. He was an important philanthropist and wanted a more permanent home for these annual performances. The setting in the Botanical Gardens would be used for the "Bowl" which was opened in 1959 some 25 years after his death.

In Sydney for the past 35 or so years there has been great free pre-Christmas Concerts for families.

The event is held in the Domain, and each year the quite large stage and the canopy is erected.

The founding President of the then MSAA (now the LSAA) was largely responsible for developing the canopy concept.

Vinzenz Sedlak started with a lycra model at a scale of 1:100 and envisaged four masts located near each corner of the stage. Diagonal cross cables spanned between the opposite mast heads and a long front edge cable gave an uninterrupted view of the stage area.

From the Spire

I recently had a short trip down to Melbourne and took a few pictures of the Arts Centre Spire which was constructed in the late 1970s.

Conceptually, the spire is a sculpture which was intended to indicate the location of something special located under the tall, tapering open lattice structure.

The "upper spire" is from bolted steel tubes with a geometry utilizing tetrahedrons so as to reduce the number of members meeting at a joint. Four joints are at each higher level and these four are rotated by 45 degrees in plan from those at the adjacent levels.

The LSAA committee has spotted two LSAA member projects in the shortlist of the World Architectural Festival 2018. Congratulations to your respective architects and the LSAA members that have contributed to the project’s success. Please let me know if I have missed a project. #WAF18

There has been a number of curved and interesting footbridges built recently here in Melbourne. See these pics:

The last of these bridges is curved and the load carrying deck (pedestrians and bicycles) creates significant torsion on the main support spine.

This bridge won a LSAA Design Award in 2016.

However, up in Vietnam, a new elevated footbridge in a heavy tourist region has some big hands appearing to support the bridge.
