How does biomimicry inspire innovative solutions in your structural engineering projects?
Biomimicry, the design and production of materials, structures, and systems inspired by nature, is revolutionizing structural engineering. By observing the intricate ways plants and animals have adapted to their environments, engineers can create more efficient, sustainable, and innovative solutions for buildings and infrastructure. Nature's time-tested patterns and strategies, often evolved over millions of years, provide a vast repository of brilliant engineering solutions waiting to be emulated.

The intricate designs found in nature are a blueprint for structural innovation. For example, the hexagonal honeycomb pattern made by bees is an excellent model for building strong yet lightweight structures. This geometric design has inspired the creation of honeycomb-like materials used in aerospace and construction, providing high strength-to-weight ratios that significantly enhance the efficiency of structures.

Biomimicry is a powerful and beautiful subject to explore, for all ages and disciplines. Materials, colors, adaptation, optimization. Bringing biomimicry to life has proven successful in many ways and many industries, implants, aerospace composites, light refraction. material optimization. Often times technology and resources costs exceed business application ROI and can be left behind. I hope the advent of AI will favor such studies driven by limit carbon emission and augment life quality. Biomimicry is one of the topic I'm most passionate about and also the subject of my PhD., Structural Form Finding was the subject of my Ph.D. happy to share papers if needed.

Nature has evolved over the years with the best possible resilience wherever needed as evolution is mandatory for survival purpose. Design styled after nature are most times very resilient, environmental friendly and efficient. Biomimicry has provided us with great solutions in design. A crucial example is Burj Khalifa whose his design is styled after the pattern of naturally occurring plant called Spider Lily. Honeycomb "interlocking" structure has been adopted pattern for geosynthetic ground stabilisation and to achieve light weight structure in aerospace. Also, biomimicry has helped to develop great aerodynamically efficient shapes by copying the structure of birds and trees / plant that are resilient in windy condition.

As for engineering, some of these ideas are being adopted in cladding materials, partitions, and false ceilings. Potentially, the use of paneled beams and similar structures is coming from applying the same concept. I have also seen this in marine works, where precast concrete is used to form natural shapes to foster biodiversity. I believe this idea can be implemented using 3D printing, which enables achieving and forming complex shapes.

Les conceptions naturelles inspirent l'innovation en construction. Par exemple, le motif hexagonal des nids d'abeilles combine solidité et légèreté. Les panneaux en nid d'abeille, avec deux couches rigides et un noyau, augmentent la rigidité tout en réduisant le poids. Utilisés pour cloisons, toitures et planchers, ils offrent une isolation thermique et acoustique excellente. Leur légèreté facilite l'installation et réduit les coûts. Parfaits pour la construction modulaire, ces panneaux permettent de bâtir rapidement tout en étant écologiques. Ainsi, les motifs naturels comme le nid d'abeille révolutionnent la construction en optimisant performance et durabilité.

To inspire towards biomimicry, we need to understand our past. Nature has shown us glimpses of our past all over the world where mankind has once lived in equilibrium with nature. The blueprints are out there, and some left us puzzled and amazed. I’m inspired by scientist and author Janine Benyus in her 1997 book Biomimicry: Innovation Inspired by Nature.
The materials found in nature often have exceptional properties that engineers seek to replicate. The strength and flexibility of spider silk, for instance, have led to the development of new materials that are both lightweight and incredibly tough. These biomimetic materials can be used in everything from bridges to earthquake-resistant buildings, offering enhanced durability and resilience.

Potentially, more research is needed to understand the behavior of these materails, its capacity, and its performance under various loading conditions. However, significant advancements have been made in the past ten years related to applying this concept ,a good example is the huge shades and halls built at Dubai EXPO by applying the concept of biomimicry.
Nature is inherently energy efficient, and its principles can greatly influence the sustainability of engineering projects. The termite mound's natural ventilation system is a prime example, inspiring architects and engineers to design buildings with passive cooling systems that reduce the need for artificial air conditioning, thus saving energy and reducing carbon footprints.

The design of a nearly zero-energy passive building involving solar passive strategies in the design and construction is an example of biomimicry. For instance, passive solar heating/cooling, building daylighting, and provision for rainwater harvesting is similar to the process of photosynthesis, whereby plants transforms light energy into chemical energy for it's nutrients. The solar passive building however, requires a knowledge of solar geometry, local climate, and window technology. The passive solar design strategies should be selected based on the climatic condition of the project site.
Observing how certain organisms withstand extreme conditions can lead to more resilient structures. The flexible yet sturdy structure of bamboo allows it to sway in strong winds without breaking, offering insights into designing buildings that can better withstand earthquakes and hurricanes. Such biomimetic approaches are crucial for creating infrastructure capable of enduring natural disasters.

En tant qu'ingénieur structure, l'observation de la nature offre des perspectives précieuses pour renforcer la résilience des constructions. Par exemple, la structure flexible mais robuste du bambou, qui peut se balancer dans les vents forts sans se briser, inspire la conception de bâtiments capables de mieux résister aux tremblements de terre et aux ouragans. En imitant les propriétés du bambou, comme sa capacité à dissiper l'énergie, nous pouvons développer des infrastructures capables de se déformer sans subir de dommages majeurs. Cette approche biomimétique est cruciale pour créer des bâtiments plus sûrs et plus efficaces, répondant aux défis posés par les catastrophes naturelles.
In structural engineering, the form of a structure is closely tied to its function. The streamlined shape of a fish or a bird's wing has inspired the aerodynamic designs of bridges and skyscrapers, reducing wind load and improving stability. By mimicking these natural forms, engineers can achieve optimal functionality with minimal material usage, leading to more sustainable design solutions.

Ailes d'oiseaux pour la conception de gratte-ciels :** Les formes aérodynamiques des ailes d'oiseaux inspirent la conception de gratte-ciels pour réduire la résistance au vent et aussi pour les piles du pont sous l'eau. Les nids d'abeilles inspirent la création de matériaux en nid d'abeille pour leur légèreté et leur résistance. Ces structures sont utilisées dans diverses applications, de l'aérospatiale à la construction, pour optimiser la performance. Les coquilles de mollusques, quant à elles, sont des modèles pour des matériaux composites et des structures légères mais solides. Cette conception biomimétique permet de créer des constructions robustes tout en minimisant le poids, offrant ainsi une solution durable et efficace.
Nature's ecosystems are models of collaboration and efficiency. In a similar vein, biomimicry encourages multidisciplinary collaboration in structural engineering projects, bringing together biologists, engineers, and designers to innovate. This collaborative approach can lead to holistic solutions that address multiple challenges simultaneously, much like an ecosystem thrives through the interdependence of its organisms.
