Model | Exhibition Greenhouse of Botanical Garden Cologne, Germany

The wings are arranged at right angles to each other in a U-shape, being divided into a main wing and two side wings. The new building is used as a palm and desert house. The orangery connects the existing subtropical house with the exhibition greenhouse over a length of about 328 ft.

The German Dlubal customer ASSMANN BERATEN + PLANEN AG was responsible for the structural analysis of the steel structure. The structural frame and truss analysis software RSTAB was used for the structural design.

Structure

The exhibition greenhouse is a steel structure with a glass roof. The external dimensions of the main area (tropical house) are L x W = 180 ft x 69 ft, those of the two smaller areas (desert house and house for useful plants) are each L x W = 112 ft x 39 ft.

The principal beams of the greenhouse are slender, curved IPEo sections, which are arranged in a spacing of 10 ft. The height of the large arches is approx. 56 ft and that of the small arches is approx. 26 ft.

Due to the shape of the arches, the stiffening in the transverse direction is achieved by a two-hinged frame. In the longitudinal direction, the arches are connected by regularly distributed coupling members. These members transfer the stiffening loads into the roof and wall bracings and thus into the foundation.
