Deep Drilling Rig   STAB As the geothermal energy market is continuously increasing, BAUER R Maschinen GmbH, a German com- pany working in the field of special- ist foundation engineering, has de- veloped a new deep drilling rig. The German Dlubal customer Ing.-Büro H.-U. Möller was in charge of the plant’s structural analysis. The system is used to make borings reaching to a depth of 7,000 m in the area of geo­ thermal energy, oil or gas. In addi- tion, it is possible to extend existing boreholes using modern boring tech- nology. The boring device is built in Germany and distributed worldwide.

When approaching they understand why the air of a typical fair is missing in its surroundings. It is not a ­ oller r coaster running with high speeds but an accessible construction with a stairway of all in all 215 m. It is not possible, however, to pass through the structure in one run because the looping is an obstacle that cannot be overcome. After 2 years of planning and comple­ ion the big outdoor sculp- t ture called „Tiger & Turtle - Magic Mountain“ was opened to the pub- lic in November 2011.

  • Designed with Dlubal Software... Shuter Street Bridge   STAB in Toronto, Canada Since March 2011 a glass ­ edestrian p R bridge with a length of 30 m con- nects the St. Michael hospital with the new research center Li Ka Shing Knowledge Institute. The ­ upporting s structure consists of several oval steel rings which are twisted together. The bridge with a section height of 4.60 m and a width of 3.80 m was designed by Diamond and Schmitt Architects Inc. from Toronto. As peo- ple in Toronto are mainly using the PATH system, an underground ­ ystem s of pedestrian paths, ­ xtending over a e length of 28 km, the town could be persuaded to grant the permit only Model with deformation visualized in RSTAB by architectural originality. Lightness of the bridge is reached by curved and thermally prestressed panes of insula­ ed glass as well as curved tCustomer Examples pipes crossing each other, all togeth- er forming the sup­ orting structure. p Thus, the construc­ ion appears dif- t ferently each time you see it from a ­ nother perspective. Structure The bridge was designed as a stati- cally determinate framework because of different building movements and the requirement that introducing ma- jor forces into the building structure is not allowed. The fixed point, and thus the transfer of horizontal forces, was put to the side of the old build- ing. The cross-section of the bridge is elliptic.
