Minneapolis Dome Collapses
The pounding snow caused the roof of the 64,000-seat Metrodome in Minneapolis to "deflate" Sunday morning, Minnesota State Patrol spokesman Lt. Eric Roeske said. Workers wielding shovels could be seen clearing the roof of the heavy white stuff, while photos from inside the darkened stadium showed much of the field covered with snow that fell from a gaping hole in the dome.
TensileDraw: the Tensile Structure Software
TensileDraw is an AutoCAD and RHINO fully compatible and integrated plug-in software package developed in collaboration with Maffeis Engineering & Consulting. It can simulate well balanced force stress distribution on the membrane surface without complicating file exportation and related compatibility problems.
The great versatility of the application is most significant: it can calculate the form of complex geometry fabric structures thanks to the generation of a warp and weft beam mesh reproducing the orthotropic behaviour of fabric material.
International Design Competition for the new Japan National Stadium
A new stadium is being proposed by Japan Sport Council that aims to be the "greatest stadium".
There has been an International Design Competition for the new Japan National Stadium and a short list of 11 international design groups has been selected.
Two reasons for the new stadium are to boost Japan's bid to host the 2020 Olympics as well as the FIFA World Cup.
Flinders Street Station Design Competition
There are six groups who have been shortlisted for the next stage of the Design Competition for revamping Melbourne's iconic Flinders Street Station.
Most groups involve local and international firms. The next stage of the process is due to be completed in July 2013 after each group develops their design concepts further and have briefings with government departments.
America Cup Boats - The Ultimate Lightweight Structure?
The new catamaran boats used in the America Cup races are a true example of a lightweight structure and embody many elements that the design of normal tensioned fabric structures take into account.
The wind loading is critical for both and the structural form required to resist or to take advantage of the wind pressures is the key element to success.
Both use highly engineered modern materials that require optimization in terms of orientation, cutting patterns and seaming technology.
The more rigid components need to be optimized also to reduce weight whilst still maintaining structural stiffness.
Congratulations to the USA for winning but also to Team New Zealand for pushing the limits.
