A shell is a three-dimensional solid structural element whose thickness is very small compared to its other dimensions. It is characterized in structural terms by mid-plane stress which is both coplanar and normal to the surface.

Shell structures, also known as shell roofs or shell forms, are architectural and engineering designs that utilize curved, thin, and lightweight structures to create a shell-like, curved surface that efficiently spans large spaces. These structures are often associated with elegant and innovative architectural designs.

Aug 11, 2023 · Shell structures offer open, flexible interior spaces ideal for sports stadiums, concert halls, and airport terminals. Their unique architectural forms, graceful curves, and flowing lines enhance their visual appeal.

Aug 10, 2023 · Shell structures are becoming an increasingly popular choice among architects and engineers primarily for their long-span structural capabilities and aesthetic appeal. Let’s have a look at some of the most promising shell structure examples across the globe.

Jan 16, 2016 · Shell structures are lightweight curved constructions made of thin shell elements like plates. There are different types of shell structures including concrete shell structures formed as domes or bridges, lattice shell structures like geodesic domes, and membrane structures made of fabric or tensile materials.

Aug 10, 2022 · The exposed single-layer reticulated shell structure is a Q390c welded box beam, located on the northwest side of the steel roof, with a total weight of more than 1000t, and a single maximum weight of 18t.

One of the most iconic examples, the TWA Flight Center at John F. Kennedy International Airport in New York, designed by Eero Saarinen, stands as a testament to the timeless appeal of shell structures. Its fluid form and seemingly weightless span capture the essence of flight itself, a fitting homage to the era of jet travel it was born into.

shell structures present unique features requiring a new approach towards the integration of structural design, detailing, modelling, and fabrication. A prominent aspect of the architectural design was the definition of a single roof characterized by a non-repetitive organic shape predominantly made of reinforced concrete [1], [2].

Jul 8, 2022 · Shell structures are self-supporting and used to cover a large area of span without any supports of beams, columns, and walls. Its efficiency is based on its curvature (single or double), which allows different stress paths and gives the optimum form for transmission of many different load types.
