English website, acoustic salutation, new projects (20.07.2006)

The translation of the german website to the english version is completed now.

Visitors now have the ability of an acoustic salutation. You can activate and deactivate the salutation pressing the new sound-buttons beside the flags.

The set of exemplary projects to demonstrate the fields of activity was extended:

• The project "Plants / Big storage / Piston gasholder" was updated. It is described that we not only offer statical calculations but also evaluate the actual conditions of a building and determine its remaining lifetime. Additionally more detailed descriptions for the verifications were given. You can find the appropriate page here.
• The project "Plants / Chimneys / Transition" was added. The transition of a chimney from the diameter D=2100mm to D=1100mm was to be designed and calculated for the temperature T=450°C. The transition was optimized in constructional and technical regards and calculated for heat resistant steel. For the cylindrical shells of the chimney the buckling verifications for local loading at the stiffeners were led. For the stiffeners and the circumferential rings the statical calculations for the stresses and the stability were performed. You can find the appropriate page here.
• The project "Tribunes / Standing" was added. The tribune with separate entrance cutouts typically is used for big soccer stadiums. You can find the appropriate page here.
• The project "Temporary buildings / Atmosphere measuring tower" was added. For the atmosphere measurement on the Cape Verdian islands a flexible tower was planned. The minimum lifetime of the tower was supposed with 10 years. The corrosion protection of the tower and the prestressed ropes were to be laid out for the increased salt concentration due to the near sea and for the increased abrasion due to the sand content of the steady wind from Africa (Sahara). The mast is prestressed with 12 ropes and consists of usual scaffold components. You can find the appropriate page here.
• The project "Temporary buildings / Stage" was added. The stage essentially consists of a podium, walls built with scaffold units on three sides and an aluminium roof with canvas cover. The walls can be open or canvas covered on two or three sides. You can find the appropriate page here.
• The project "Temporary buildings / Advertising banner" was added. During the soccer world championship 2006 an advertising banner with the size of approximately 27m·44m was attached to the gasholder Stuttgart. The banner was supported by vertical and horizontal ropes which were attached at the stanchions of the gasholder. To avoid fluttering the ropes were prestressed. It was shown that the stresses from the additional banner loads stay uncritical. You can find the appropriate page here.
