ALL-GLASS PAVILIONS

The first glass pavilion is a transparent extension of the detached house to the garden of the client. The pavilion is 8,6m long, 5,8m wide and 4.2m high. The structural system consists on one hand of a glazed steel frame with four stanchions rigidly fixed to the base plate and connected by four transoms at the top and on the other hand of two laterally glass attachments. These are made of vertical load bearing glass walls and a horizontal glass roof, which are connected among each other by structural sealants. Together with an anchor profile that is completely hidden in the joint gap, the glass elements are also acting as bracing elements. Specifications of the building authorities called for a structural concept of the pavilon’s glass attachments for different states of destruction; in addition, extensive requirements had to be fulfilled to obtain a special building permit for the structural sealants. The project is an outstanding example for the possibilities in constructing with glass. It combines the structural features of a load bearing all glass building with state-of-the art joint techniques. The second pavilion, 8m long, 8m wide, 8m high, is under design at present.

THE APPLICATION OF GLASS AS A BRACING ELEMENT

In a current research project at the Universität der Bundeswehr München a timber glass composite shear wall has been developed and tested.

With the goal to apply glass into a bracing element, a force-fitted connection between the timber frame and the glass pane is realized through blockings. These are disposed near the corners of the glass pane as in a common window. In this way the system enables the load transfer of horizontal forces through compression diagonals within the glass pane. Besides the load introduction into the glass through its edges, the stability of the pane is an important criterion for the maximum load of the system.

The experiments and numerical studies of this research are the basis for a long term monitoring project in a real life situation.

Geralt Siebert is now working on structural use of glass since two decades. He is registered independent consulting engineer, after receiving full professorship his international active consulting engineer’s office is conducted by his wife Barbara. Since 2003 he is Professor for structural design and building physics at Universität der Bundeswehr München (Germany). Besides giving lectures Geralt is leading a research group working on R&D projects related to the structural use of glass used in civil engineering and solar industry. In the accredited laboratory for structural engineering not only testing for research and development but also of glass elements for applications worldwide is carried out. Geralt is author of several publications. Beside others he is chairman of national German standardization committee AA 005-09-25 (Glass in Building – design and construction rules DIN 18008), member of several national and international committees like CEN TC 129 WG8 and CEN TC 250 SC11 (Eurocode for glass).
