      abstract     = {Lightweight structures are widely used across different
                      industry sectors. However, they get easily excited by
                      external influences, such as vibrations. Undesired high
                      vibration amplitudes can be avoided by shifting the
                      structural eigenfrequencies, which can be achieved adapting
                      the structural design considering optimisation procedures
                      and structures primarily inspired by diatoms. This
                      procedures has been applied to the development process of a
                      girder structure installed in a synchrotron radiation
                      facility to support heavy magnets and other components. The
                      objective was to design a 2.9 m long girder structure with
                      high eigenfrequencies, a high stiffness and a low mass.
                      Based on a topology optimisation result, a parametric
                      beam–shell model including biologically inspired
                      structures (e.g., Voronoi combs, ribs, and soft and
                      organic-looking transitions) was built up. The subsequent
                      cross-sectional optimisation using evolutionary strategic
                      optimisation revealed an optimum girder structure, which was
                      successfully manufactured using the casting technology.
                      Eigenfrequency measurements validated the numerical models.
                      Future changes in the specifications can be implemented in
                      the bio-inspired development process to obtain adapted
                      girder structures.},
