A bending-active system generates form through the elastic deformation of materials. In conventional architectural design, elastic deformation has generally been minimized. However, advances in digital technology have enabled the structural analysis and simulation of elastically deformed forms, allowing bending-active systems to emerge as a viable design approach. This approach is particularly effective for producing curved forms, which have traditionally required considerable cost, labor, and time to develop. In contrast, bending-active systems generate such forms more efficiently by exploiting the structural behavior of bending.
Although structural simulation is commonly used to model elastically deformed shapes, the process often requires significant computational time. This paper therefore examines the geometric relationships underlying deformation caused by elastic bending and proposes an alternative method for modeling such forms more quickly and easily. Furthermore, because the degree of deformation can be controlled according to the magnitude of the applied force, bending-active systems enable gradual form manipulation. This characteristic makes it possible to use bending-active modules to generate a variety of forms.
Unlike conventional modular design approaches, in which form results from the aggregation of modules, this study adopts a form-conversion strategy in which the target form is first defined and modules are then arranged to fit it. By applying bending-active modules to a doubly curved surface and rationalizing the resulting configuration, this paper demonstrates the feasibility of fabrication and validates the proposed design methodology.
