The technology of new generation

NPS_pay_yelEvolved self-supporting structures made of steel and concrete, NPS® SYSTEM is a high performance new generation construction technology which also has high seismic resistance. Created by Tecnostrutture, the Italian market leader in the production of prefabricated steel and concrete structures.

THE SYSTEM
NPS® SYSTEM is an additional response designed by Tecnostrutture to meet the need for enhanced on site industrialisation, which combines a better seismic behaviour and performance quality of all components, which in turn are CE and EN 1090 certified.
By launching NPS® SYSTEM, Tecnostrutture presented the international market with a challenge by choosing to introduce a construction technology at BAU 2013, the international trade fair of architecture, materials and systems held in Munich from 14 to 19 January 2013, which allows a building to be scanned like a unique structural system consisting of vertical and horizontal structures, regardless of the calculation of components taken individually.

A complete prefabricated construction technology that combines all the structural elements of a construction in a single solution: beam, column and floor. A complete, innovative, safe, high-performing, eco-friendly and CE and EN 1090 certified response, as required by the most recent EU regulation on the performance characteristics of the structural steel components. Hence, Tecnostrutture was the first to certify its production in February 2012.
NPS® SYSTEM is the new frontier in Tecnostrutture construction technology developed after a decade of research carried out in collaboration with the major Universities and Research Centres in Italy as well as overseas.

An evolution in self-supporting structures made of steel and concrete, NPS® SYSTEM enriches and enhances the seismic response of the structure: it is more reliable and satisfies the project requirements better with more attention paid to the environmental impact.
Once again, thanks to the driven research, which resulted in Tecnostrutture filing more than 20 patents in recent years, the company has anticipated the market demand and provides designers and enterprises with a construction technology that can be controlled in every single moment of the production process, thereby guaranteeing reliable responses in terms of prevention of seismic risk as well as actual on site industrialisation.

THE INTERVIEW
Calvi prof.Sullivan prof.We asked a few questions to Gian Michele Calvi, Professor and Director at the UME School IUSS Pavia, President of the EUCENTRE Foundation and to Timothy Sullivan, Professor in Theory and Design of Steel Constructions at the Faculty of Engineering, University of Pavia and Head of Design Methods at EUCENTRE.

- Can the introduction of construction technologies that consider the building as a unique and integrated structural system and not a combination of single vertical and horizontal elements help reduce the vulnerability and probability of a building collapsing?
I believe there lies no doubt in the fact that a building must be designed, planned, analysed and tested as a unique system; not only in structural terms but also in relation to non-structural elements, installations and content. The introduction of integrated structural technologies that help this single view is certainly useful for better control of the response to seismic action and is a more reliable estimate of the performance of the buildings for different levels of movement.

- In this respect, is NPS® System a valid construction technology?
Considering that any construction technology can lead to acceptable performance if used correctly, there is no doubt that the response and performance mentioned in the previous comment can be controlled better by industrialising the building production, just like that proposed by the NPS system.

- Which are the most important aspects of the NPS® technology in relation to the structural performance and requirements expressed by designers?
An important aspect is related to the factory production of essential parts that control the response, followed by on site operations that can guarantee continuity between the elements and eliminate connection problems. A second aspect is the ability to configure various performance monitoring modes, with frame structures designed with a strong hierarchy in the critical areas, that is with combinations of pendular frame structures and shear resistant elements (walls or counter wind).
