At the recent CSIC Research Talk Dr Carlo Olivieri, Assistant Professor of Structural Mechanics at Università Telematica Pegaso, presented pioneering advancements in the analysis and design of compressed shell structures, with a particular focus on block-based shells. In his talk, titled Airy Stress-based Approach for Assessment and Design of Compressed Shells, Olivieri discussed collaborative research aimed at enhancing both the precision and efficiency of constructing architecturally ambitious shells.
The talk’s central theme was Membrane Equilibrium Analysis (MEA), an innovative method based on the Airy stress function that provides equilibrium solutions under combined vertical and horizontal loads. MEA enables designs that remain entirely in compression, supporting the construction of new shells as well as the conservation of historic masonry structures. Recent developments in MEA have refined equilibrium solutions, making it a valuable tool for assessing older vaulted structures and creating resilient block-based shells.
Olivieri also highlighted digital innovations, including Augmented Reality, which streamline the assembly process and help meet the strict construction tolerances these shells demand.
The projects, developed by the Form Finding Studio—an engineering firm founded by Olivieri, Sigrid Adriaenssens (Princeton University), and Vittorio Paris (University of Bergamo)—in collaboration with partners such as SOM and Joe Thompson Architects & Landscape, were presented in the talk through case studies that showcased the practical application of their methods. Notable examples included the Angelus Novus Vault at the 2023 Venice Architectural Biennale, the SOM Pavilion for COP28 in Dubai, the I Live with Nature pavilion in Shenzhen, and the IMI Workshop pavilion.
These projects demonstrated the potential of combining traditional masonry techniques with modern engineering principles to produce sustainable, resilient, and visually compelling structures.
