L'eredità scientifica e morale di Arturo Danusso
No full textIl saggio ripercorre in modo critico l'attività di ricerca dell'ingegnere Arturo Danusso che, a quasi cinquant'anni dalla sua scomparsa, è ancora presente nei testi della letteratura scientifica. La rilevanza internazionale del suo pensiero, sia in relazione agli studi di ingegneria sismica che allo sviluppo di nuove concezioni per le strutture in cemento armato, quali ponti, edifici alti ed interventi di restauro, è ancora oggi estremamente significativa
Performative Building Skin Systems: a Morphogenomic Approach Towards Developing Real-Time Adaptive Building Skin Systems
No full textMorphogenomics, a relatively new research area, involves understanding the role played by information regulation in the emergence of diverse natural and artificially generated morphologies. Performative building skin systems as a bottom-up parametric formation of context aware interdependent, ubiquitously communicating components leading to the development of continually performative systems is one of the multi-scalar derivations of the aforementioned Morphogenomic understanding. The agenda of adaptations for these building skins specifically corresponds to three domains of adaptation: structural, behavioural and physiological adaptations resulting in kinetic adaptability, energy generation, conservation, transport and usage principles as well as material property based changes per component. The developed skins adapt in real time via operating upon ubiquitous communication and data-regulation protocols for sensing and processing contextual information. Computational processes and information technology based tools and techniques such as parametric design, real-time simulation using game design software, environmental information mapping, sensing and actuating systems coupled with inbuilt control systems as well as manufacturing physical models in collaboration with praxis form a vital part of these skin systems. These experiments and analysis based on developing intrinsic inter-dependencies between contextual data, structure and material logistics thus lay the foundation for a new era of continually performing, self powering, real-time adaptive intelligent building skin systems
Spiritualità e conoscenza nel lavoro dell'ingegnere
No full textIl libro raccoglie tutti gli scritti di Arturo Danusso, saggi dispersi in pubblicazioni introvabili ed occasionali, lezioni e conferenze di fatto irreperibili, da cui emerge la forza etica e la dimensione spirituale della sua concezione scientifica: la suggestiva documentazione di una visione in cui scienza e morale si integrano nella consapevolezza che l'impegno più importante richiesto a un progettista è soprattutto quello di fare bene il proprio mestiere
HISTORICAL REINFORCED CONCRETE HIGH-RISE BUILDINGS
No full textNon-ductile reinforced concrete structures built in seismic areas before modern design codes were introduced are an important fraction of the building stock worldwide and strongly condition its
vulnerability. Some of these buildings, for their architectural and historical characteristics, are now considered part of the cultural heritage of their countries. As a consequence, special considerations may apply in assessing their vulnerability and, particularly, in defining possible intervention criteria for their seismic improvement. The case of two high-rise buildings of particular value in Italy, the Velasca Tower and the Pirelli Building in Milano, Italy, are examined. The design data available for the two buildings made possible to evaluate the response to loads and seismic action currently imposed by design codes, permitting to assess their adequacy and to develop some general onsiderations on historical concrete buildings in seismic areas
An innovative system for post-emergency timber housing
No full textThis research aims at investigating a possible layout of a temporary house that
could be unfolded in situ through a pneumatic system. The innovative system consists of a
triangular shaped timber frame that could be easily compacted in order to form a beam
like structure for transportation. Once placed in situ each timber frame could be restored
in shape and assembled with other frames to realize this modular temporary housing. The
paper analyses the structural performance of this modular house, through a Finite
Element model, taking into account different aspects such as the possibility of fitting
together and disassembling the modules and their capacity to bear the main loads acting
on the structure (snow, wind and earthquake). In this respect, as this timber shelter could
be used in a post-emergency situation, the module has been verified also with the data of
the response spectrum of the Nepalese earthquake that struck Kathmandu valley in April
2015. All the performed analyses confirm the ease of construction of this housing solution
and its proper structural behaviour in terms of stress in the elements, displacements and
supporting system
Moon exploration habitat using in-situ sulfur concrete
No full textConcepts for space exploration habitats have been proposed since longtime before the
dawn of the space age. Twenty years after the original manned Moon landing, a group of scientists and
engineers at the Johnson Space Center (JSC) started to consider the return to the Moon for living
purposes. Since 1986, several types of structures have been proposed for both Moon and Mars concept
settlements. The possibility of utilizing unprocessed or minimally processed in-situ materials for these
structures, as well as for shielding from the cosmic radiations, may be possible by adopting and extending
terrestrial techniques developed for harsh environments. Therefore, this research leads to evaluate the
structural performance of a possible Moon architecture layout thanks to the recent discoveries related to
the possibility of using in-situ materials, such as the Moon regolith. In this paper, an architectural layout
is proposed for a human habitat on Moon; specifically, shells structures are designed, making use of
mixed and self-assembled regolith, thanks also to robotic fabrication processes (such as 3D printers)
