Steel Membrane Roofing in Nairobi, Kenya

This customer project is a steel membrane roofing in Nairobi, Kenya. The prestressed fabric membrane system made of Mehler fabric is supported by seven curved steel arches made of S 235 steel. It serves as a semi-covered area next to a swimming pool, protecting hotel guests from the sun and blending seamlessly into the surrounding landscape.

This structure, designed by Dlubal customer Savana General Trading, was designed using RFEM. The geometry of the membrane was adjusted and refined to achieve optimal distribution of the pre-tensioning forces, while also meeting aesthetic and architectural space requirements.

The seven-arch structure allows for efficient force transmission to the foundation and the rear wall. The main load-bearing elements consist of steel tube sections designed and implemented as spatial arches. These arches not only withstand wind loads and membrane tension, but also serve as architectural highlights in the overall design.

During the structural design process, nonlinear analyses were carried out, taking into account initial geometric imperfections, evaluating the risk of water ponding on the membrane, and simulating wind behavior using CFD in RWIND software.
