Topology Optimized Concrete Structures
Asbjørn Søndergaard, Aarhus School
of Architecture
Aarhus School of Architecture has been conducting a series
of design experiments with topology optimization on pre-cast
concrete structures. The aesthetic and structural potential
for topology optimization within architectural design has
been explored, showing significant potential for design innovation.
Topology optimization can be utilized not only to reduce use
of building material and increase constructional member stiffness,
but also to add sculptural value to concrete elements. The
aim of the research has been to investigate the potential
of topology optimization as a design tool used not only to
increase structural efficiency but also to inspire new formal
morphologies. As aesthetic values cannot reasonably be validated
through numerical evaluation, only structural criteria can
be directly utilized as an objective for an algorithmic optimisation
process. But as the optimisation process itself is a linear
result of the optimisation algorithm, aesthetic reflections
can be indirectly imbedded within the calculation by evaluating
the initial optimisation output, and then applying adjustments
to the model. The presented research show methods to imbed
aesthetic intentions within the optimisation setup, thereby
improving the visual appearance of the design.
