Two Dlubal customers were engaged in this project. The German engineering office Wagner used RSTAB to perform the structural analysis for the roof structure and WIEHAG GmbH from Austria was responsible for the timber construction.
Structure
The center symmetrical tented roof has 12 roof surfaces. Its shape is based on two glued-laminated timber rings; a round ring outside and an octagonal ring inside. Twelve hip rafters form the main beams of the roof structure.
The valley and jack rafters transfer the roof loads from the external ring to the hip rafters. The connections were carried out with slotted sheets, as the roof is a timber structure with wooden elements that are intended to be seen.
The timber roof is supported by steel columns consisting of rectangular and square hollow sections.
Structural Analysis
First, the structure was modeled in cadwork. Then, it was imported to RSTAB using the interface. The engineering office Wagner used add-on modules by Dlubal Software for the design of the frame structure.
