This paper presents an extension to the Combinatorial Equilibrium Modelling (CEM) design framework. So far, CEM gives the possibility to generate and explore multiple spatial equilibrium solutions in the early conceptual design phase. In addition to the fo ...
Graphic statics has been strongly employed as a method to analyze and design structures. Whereas the former use is well documented in literature, the latter has been rarely discussed. Based on a close investigation of original working-drawings, this paper ...
This paper explores the geometric optimization of a planar reciprocal frame (RF) floor framing structure, focusing on the triangular topology. The structural performance of the frames is computed and plotted against the geometric parameters for various loa ...
In 1909, Rafael Guastavino Jr. designed the 93-foot-wide dome of the Cathedral of St John the Divine, Harlem, NY. As the thinnest brick shell in the world, the dome is also a clear example of construction efficiency and material optimization. This paper re ...
Structural robustness is related to the insensitivity of a structure to local failure, which is linked to the ability of force redistribution. Current approaches—probabilistic, risk-based, deterministic, and energetic—are poorly suited to inform the design ...
The geometric relationships between a structural configuration and its internal force distribution have not received much attention for nearly hundred years. Directly stemming from the most fundamental principles of statics, the underlying theories were br ...
One of the most crucial components of a tall building is its lateral loading system. In this paper, we provide the development of a lateral bracing system that results in bracing material savings of up to 50% relative to a traditional X-Bracing system, as ...
The reciprocity between form and force diagrams in 2D graphic statics makes it possible to manipulate the form diagram while directly evaluating the redistribution of the forces within the force diagram. Conversely, after modifying the force diagram, the c ...
This paper shares the authors’ experience regarding the Forces Frozen workshop developed in MIT’s Building Technology Program, within the Department of Architecture. This one-week outdoor workshop invites students to physically explore the world of structu ...
The evaluation of the equilibrium of a system of forces that fulfils specified boundary conditions is a core question of theory of structures. This paper reviews three methods, related to procedures introduced at the end of the 19th century, to evaluate th ...
