Municipal Intermediate Highschool Memmingen

Project Description

The structural system of the building having a nearly square-shaped plan and a partial basement was originally designed as a reinforced concrete skeleton construction.

The floor slabs are mainly laid out as 30 cm thick flat slabs with concrete core activation, predominantly point-supported along the façade perimeter.

The columns along the façade are designed as steel/concrete composite columns with a massive steel core profile. Column diameters range from 220 mm to 200 mm, respectively, for the ground floor and the upper levels.

The final building design includes column-free areas in the north and the south with cantilevering parts in the 1st and the 2nd floors. In order to enable this architecturally ambitious concept, the three-dimensional load bearing system is created by using diaphragm walls in combination with the diaphragm action of the adjacent slabs. Furthermore, for bridging of the recreation hall and the music hall as well as the school café, walls located above are used as load bearing deep beams.

The monolithic concrete basement, constructed as a “white tub” type of concrete construction with a high resistance to water penetration has a wall thickness of 25 cm. In areas of higher column or wall reaction forces, the foundation plate having a regular thickness of 30 cm is locally tapered and reaches a total depth of 60 cm. It is resting on a properly laid out replacement body of soil to transfer the loads into the sufficiently load bearing subsoil regions.

The façade area is consisting of a mullion-transom system made of timber with a fire rating of 30 minutes. The roofing of the northern atrium is executed as a steel-glass construction.
