Ultra lightweight architecture: foldable and expandable shelters for humanitarian relief. From containers to kits: evolution of lightweight sheltering systems
No full textThis article explains how and when lightweight architecture has developed, how it works and which are its basic
principles. Structures that come ready to assemble, that can be erected and disassembled in a matter of hours and those
that have the last impact on the natural environment while providing adequate shelter and modern amenities, are the
preoccupation of several architects whose ambitions are not only toward the micro but the autonomous. Anyway, most
of these features are not known and that’s why, in this dissertation, foldable and expandable architecture are shown and
their features are highlighted (part a.). The article continues explaining how these kind of solutions can be adapted to
suit the needs of victims in case of emergencies and some of the few applications are presented (part b.). The conclusion
(part c) focuses on the weak points about the application of such structures in emergency to foreseen possible fields of
improvement. A detailed bibliography about the topic is provided in annex
Interaction between fiber-glass profiles and membranes for building active tensile structures
No full textStudio dell'utilizzo di materiali con particolare comportamento elastico come elementi che possano tensionare il tessuto di tensostrutture o strutture temporanee in generale. Il testo descrive anche test sperimentali e la costruzione di un prototipo con il principio esposto
Rapid deployable kits for post disaster response
No full textThis paper aims to give a general overview of the state of the art of the current solution available and presents possible solution and alternatives to the problems which arise from the use on the field. The structural principle of tensairity® has been identified as an useful technology to combine the current needs of humanitarian sector, solving some of the problems listed above and tiring to came out with solution based on high tech concept but low tech in construction
Time Dependent Behaviour Of GFRP Pultruded Profiles And Polyester PVC Coated Fabric For Building Composite Active Tensile Structures
No full textAn investigation dealing with the use of unidirectional fiber-glass profiles for building spatial structures is presented in this paper. The research aims to experiment the feasibility of the combination between a structural frame, made of pultruded E-glass/Polyester profiles, and a membrane, made of polyester PVC (PES/PVC) coated fabric, to create ultra-light building systems
DESIGN TOOLS FOR INFLATABLE STRUCTURES
Full text linkThis paper shows different tools and approaches that can be useful for the definition of the design of pneumatic structures. Some of these tools have been applied for the design of a Tensairity® hull
Innovative solutions for ultra-lightweight textile shelters covering archaeological sites
No full textThis paper describe the design approach and the manufacturing techniques adopted in a pilot project for an innovative ultra-lightweight shelter covering the mosaics of a roman settlement in Sardinia.
The shelter is based on the combination of a membrane structure supported by fiber reinforced polymer composites and investigates the wide range of potentialities offered by Composite Active Tensile Structures in the preservation of historical finds
Design of inflatable complex shapes and geometrical analysis of pneumatic structures
No full textInflatable structures obey to strict and well known equilibrium rules but the definition of complex shapes remains a challenge. Simplified tools, based on generative models are becoming more popular among designers and architects and seem to be useful for pneumatic structures too thus, some of the potentials of these tools are showed in this paper
