A network structure consisting
of Deltaribs. Each rib is made of three curved
sheets. | Delta Ribs are structural
elements for buildings with irregularly curved shapes. Whereas such shapes
would conventionally lead to highly complex and often heavy structures,
Delta Rib-structures can be shaped according to the architectural and
structural needs. Through twisting and curving the system can follow the
contours of curved building envelopes, facades and canopies.
The solution to this demanding brief is to create
ribs of triangular cross section from three bespoke curved sheets of
steel. Next, a number of ribs together constitute a network
structure. Neither the ribs nor the network in which they are
applied consist of standard components; both are custom-designed by
the designer. The principle works with four sheets too, but three is
the minimum to create a closed section. |

The
underlying principle of Deltaribs: three intersecting single-curved
surfaces. |
Three examples of Deltaribs. The
ribs' non-constant cross sections
that allows following the local structural need, and
connect to other ribs without any jumps. |
