Article
The Parigi mechanism, invented by the author, is described and defined rigorously with the use of the kinetic reciprocal system (KRS) algorithm. The mechanism possesses one degree of freedom (DOF) and consists of a network of elements reciprocally connected with pin-slot joints. The network can be extended infinitely and retain one DOF, regardless...
Conference Paper
The geometry of reciprocal structures is extremely difficult to predict and control, and it cannot be described with the available CAD software or by hierarchical, associative parametric modellers. The geometry of a network of reciprocally connected elements is a characteristic that emerges, bottom-up, from the complex interaction between all the e...
Article
Due to their non-hierarchical nature, the geometry of reciprocal assemblies cannot be described conveniently with the available CAD modelling tools or by hierarchical, associative parametric modellers. The geometry of a network of reciprocally connected elements is a characteristic that emerges, bottom-up, from the complex interaction between all t...
Article
Reciprocal systems based on superimposition joints, i.e. where un-notched bars sits on the top or in the bottom of each other, could be regarded as being intrinsically three-dimensional because of their natural out-of plane development. This paper presents seven of these three-dimensional configurations, conceived and built by the students of the M...
Article
Planar reciprocal frames are two dimensional structures formed by elements joined together according to the principle of structural reciprocity. In this paper a rigorous formulation of the static and kinematic problem is proposed and developed extending the theory of pin-jointed assemblies. This formulation is used to evaluate the static and kinema...
Conference Paper

This paper discusses teaching of technical subjects in architecture, presenting two experimental activities, recently organized at Aalborg University -a two week long workshop and a one day long lecture. From the pedagogical point of view, the activities are strategically placed between conventional disciplinary courses and architectural design stu...
Conference Paper
Full-text available
This paper present seven different three dimensional structures based on the principle of structural reciprocity with superimposition joint and standardized un-notched elements. Such typology could be regarded as being intrinsically three-dimensional because elements sit one of the top of the other, causing every configuration to develop naturally...
Conference Paper
Full-text available
This paper deals with the principle of structural reciprocity, considering its origins in both Occidental and Orient culture and aiming to highlight the definition, main characteristics and interesting aspects of such concept referring to its application to the world of construction. Issues spanning from history, form-finding and morphology, struct...
Article
Reciprocal Frames are an interesting but almost unknown class of structures, based on the assemblage of straight one dimensional elements into spatial structures. They differ from truss structures because elements are joined by contact at intermediate and end points, and they can reach stability without the need of pins. RF aroused lively interest...

The paper presents a method to generate the geometry of reciprocal structures by means of a hybrid optimization procedure. The geometry of reciprocal structures where elements are sitting on the top or in the bottom of each other is extremely difficult to predict because of the non-hierarchical nature of such assemblies and the intrinsic three dime...
Article
The present paper considers control of responsive architectural structures for improvement of structural performance by recognizing changes in their environments and loads, adapting to meet goals, and using past events to improve future performance or maintain serviceability. The general scope of the paper is to discuss control strategies for respo...
Article
Kinetic Reciprocal System (KRS) are a new kinetic system based on the principle of reciprocity [1] with internal pin-slot constraints. A morphogenetic procedure that can handle a set of many rigid bodies interconnected reciprocally with multiple pin-slot constraint was developed for the generation of pin-slot paths starting from the local displacem...
Article
Full-text available
p. 1885-1894 Reciprocal frames and reciprocal structures have already been considered of great interest in the past, as witnessed by the work of Leonardo da Vinci and of other important scientists and architects. Recent researches show that both the shape and the mechanical behaviour of such structures are really complexes, due to the concept of re...
