The new sports hall of the Alice Salomon School in Hanover is exceptional from an architectural and structural point of view. The timber structure stands on a reinforced concrete first floor and cantilevers above it at the sides about 5.5 m.

Dlubal customer MARX KRONTAL PARTNER was responsible for the structural analysis and used RSTAB for it.
Structure
The ground floor, made of reinforced concrete, includes four classrooms and locker rooms. Above that, a two-span hall was built as a timber structure. The visible roof structure is an essential design element of the hall interior. The hall is completely acoustically decoupled from the ground floor. Elastomer bearing strips under the timber-concrete composite slab form the only support of the hall structure.
The cantilever of the upper floor is made by truss structures integrated into the wall panels. The nodes are a special feature. On one hand, they are designed in such a way that the wall panels can be delivered to the construction site as closed, prefabricated elements and assembled on site to build a complete structure. On the other hand, the connection details with high load-bearing capacity and low deformation have been developed using inclined, fully threaded screws subjected to tension.

Timber Member Compression Perpendicular to the Grain acc. to NDS 2018 and CSA O86:19
A standard scenario in timber member construction is the ability to connect smaller members by means of bearing on a larger girder member. Additionally, member end conditions may include a similar situation where the beam is bearing on a support type. In either scenario, the beam must be designed to consider the bearing capacity perpendicular to the grain according to the NDS 2018 (Sect. 3.10.2) and the CSA O86:19 (Clause 6.5.6 and 7.5.9). In the new generation RFEM 6 and Timber Design add-on, the added feature 'design supports' now allows users to comply with the NDS and CSA bearing perpendicular to the grain design checks.
- Why do the results of members and sets of members differ in the design?
- The load distribution on my members looks different when using the Load Transfer surface vs. the Load Wizards. What is the reason?
- How can I efficiently define line hinges on several surfaces?
- Why cannot I define a rotation when defining layers?
- How do I create an imperfection based on a mode shape in RFEM 6?
- Why does the load wizard "Member Load from Area Load" give unnecessary concentrated loads?
- Why does the eHORA map of Austria give different snow loads than your Geo-Zone tool?
- How can I carry out case-related design for different load situations?
- How can I modify the lamella thickness for a glulam section in RFEM 6?
- How do I define a member as a cantilever and not as supported at both ends for serviceability or deflection design?
