Box frame construction

Atelier 5: Flamatt 1 residential development

The apartment block shown here, designed by the Atelier 5 team, illustrates a typical use of parallel shear walls (or cross walls). They separate the individual apartments and on the standard f loor determine the dimensions of the living room. The south facade reflects this loadbearing structure, which limits the openings on all sides (structural opening). The inclusion of loggias further emphasises the principle of the box frame construction.

The shear walls and the floors form the primary structure and are built of i n situ concrete, while the partitions within the apartments consist of storey-high, precast concrete elements.

El-Azhar Mosque in Cairo

The prayer halls of the Islamic world are the earliest examples of large open-plan interior spaces. They are based on an orthogonal column grid square - and hence unidirectional - in the case of the El-Azhar Mosque.

Nevertheless, the linear arches do lend the interior a certain directional quality which, however, is in turn weakened again by the transverse beams (for lateral stability), which seem to introduce an intermediate level. In terms of the l oadbearing structure this is a classical box frame with parallel longitudinal walls and f loor bays spanning the space below. However, the shear walls have been dissolved to the barest essential as columns and arches thus giving the impression of a wide open space.
