New structural optimisation system

Bellapart and Strain Collaborate together in the development of a new structural optimisation system combining mathematical algorithms and finite element analysis software. The project proposes the investigation of a new structural optimisation system for the calculation of shell structures through the combination of mathematical algorithms and finite element analysis software.

Shell structures are one of the most efficient structures in nature. They are characterised by a very high load capacity, high stiffness by minimal material used. They have an excellent structural behaviour and they are also architecturally pleasant.

Shell structures, and more precisely domes, have been widely used for a long time to cover big spans avoiding the use of intermediate pillars. The great improvements in computational analysis have permitted to calculate, project and build in a very efficient way and with a high degree of prefabrication freeform shell structures. Normally this kind of structures are composed by a resisting steel/aluminium structure covered by a cladding that can, or cannot be structural or contribute partially in the resistance of the assembly.

The aim of this algorithm will be the morphologic optimisation of structures, with their consequent economical optimisation taking into account its loads (dead load, use, wind and snow).

In future projects it will be possible for Bellapart to improve its production system making it quicker and easier to design a new freeform shell structure.
