Shaken but overlooked: efficiency, economy and elegance in earthquake-prone areas

Are structures outside of the Euro-American canon being overlooked when we discuss structural art? In an essay that was selected as one of three finalist submissions for the 2018 SOM Structural Engineering Travel Fellowship, Tim Michiels argues through examples from Japan and Mexico, that extraordinary structures built in earthquake-prone areas do not always receive the attention they deserve. 1. Celebrated structural art is underrepresented in … Continue reading Shaken but overlooked: efficiency, economy and elegance in earthquake-prone areas

Design-and-build bamboo shells

Bamboo is a building material that lends itself excellently to the construction of sustainable gridshells. Two of the Form Finding Lab’s graduating senior students, Lu Lu and Russell Archer (’16), worked under the guidance of PhD candidate Tim Michiels and Professor Adriaenssens on the analysis of a set of hyperbolic paraboloid (hypar) gridshell roofs in Cali, Colombia. The Form Finding Lab’s team collaborated closely with … Continue reading Design-and-build bamboo shells

Form exploration of shells in seismic areas

News broadcasts showing images of collapsed buildings, ravaged roads and torn-apart cities regularly remind us about the destructive power of earthquakes. While decades of research have greatly improved the understanding of these cataclysmic events, building professionals and researchers continuously try to adapt and employ the most sophisticated numerical methods to improve the behavior of buildings during a seismic event in order to safeguard their occupants.

Researchers at the Form-Finding Lab of Princeton University (http://formfindinglab.princeton.edu/) are exploring the design of elegant and expressive structures that can safely be employed in seismic areas. They focus on shell structures, which are very thin, curved and typically large span structures made out of wide range of materials going from steel and glass, to concrete and even bricks or mud.
