The reconstruction of the SSB bus depot in Stuttgart Gaisburg, which was destroyed by a major fire in 2021, is currently underway. The future depot consists of twelve individual modules. Each module is made up of 5 wooden roof lenses with 4 membrane fields stretched between them. Two modules are always next to each other and are separated by firewalls with sufficient overhang in the longitudinal direction. On the sides, the system is shielded from the weather by walls. The roof structure of curved glulam beams stabilized with steel tension bands alternating with the saddle-shaped PVC membrane surfaces was not chosen solely for architectural reasons. At high temperatures, such as those caused by a fire, the seams of the membrane roof surface open and make an important contribution to the fire protection concept of the facility through smoke extraction, degassing and heat reduction. The otherwise critical property of the temperature-dependent strength of membrane weld seams is used functionally in this case and offers further application options in this direction in the future.
