ABSTRACT

This research work targets the design and optimization of a bio-inspired pedestrian
bridge. The bridge is made of lattice material, whose stress analysis is conducted
by means of the theory of asymptotic homogenization, coupled with an optimization
process that tailors the material properties to meet the functional requirements of
the bridge. The analysis requires decoupling the system into two levels, system and
component; the former represents the whole superstructure, the latter the cross-
section of the bridge. The optimum solution describing the material properties of the
bridge mapped into a lattice geometry, which enables the fabrication of the structure
using additive manufacturing.
