NPS® SYSTEM - Смешанная балка и колонна

NPS® SYSTEM is an integrated structural technology that favours a unitary vision of the building, allowing better control of the response to seismic actions and a more reliable estimate of the building's performance for the different levels of seismic shaking.‎ An industrialisation of building production, such as the one proposed by NPS® SYSTEM, favours the control of the seismic response and performance of a building that must be conceived, designed, analysed and verified as a single system, not only in structural terms, but also in relation to the non-structural elements, the systems, and the contents.‎The in-plant production of parts essential to the control of seismic response is the fundamental characteristic of NPS® technology: it is possible to configure the different performance control modes with frame structures designed with a strong hierarchy of critical zones, i.‎e.‎ with combinations of pendulum frame structures and shear resistant elements (walls or bracing).‎Obviously this must be followed by on-site operations that guarantee continuity between the elements and eliminate connection problems.‎ NPS® SYSTEM is the complete, innovative, safe, high-performance, eco-sustainable and CE EN 1090-1 certified answer, as required by the most recent European regulations on the performance characteristics of structural steel components for which, unique in Italy, Tecnostrutture has certified its production since February 2012.‎ NPS®SYSTEM COMPONENTS NPS® SYSTEM offers a complete and evolved range of horizontal structures compatible with all types of floors.‎ They are quick and easy to assemble and totally self-supporting.‎ The NPS® vertical elements make it possible to optimise interior spaces while guaranteeing safe elevation of the decks.‎ NPS® special solutions, on the other hand, are designed for difficult building sites and deep construction.‎ THEADVANTAGES OF NPS® SYSTEM TOTAL SELF-SUPPORTANCE With NPS® SYSTEM there is no need for provisional propping of the beams during erection, the structures can be loaded from the day after casting, allowing an overlapping of the work phases that speeds up the construction site.‎ For example, during the installation of the second deck, it is already possible to install the systems on the first floor cast a few days earlier.‎ The NPS® line includes a complete range of steel-framed beams that meet all site requirements.‎ SPEED EASE OF INSTALLATION It only takes 5 minutes, 2 workers and 1 crane operator to place an NPS® Beam.‎ Watch the video.‎ 8 minutes to place an abutment.‎ NPS® SYSTEM ensures fast assembly and erection of structures with a productivity of over 19,000 m2/month compared to a maximum of 13,000 m2/month with the self-supporting formwork system.‎ The speed of construction translates into a fast return on investment for the client of the work.‎ SAVINGSAND CERTAIN COSTS Savings can be quantified in all cost factors: -30% of concrete, -90% of labour, -90% of timber, and -97% of the metal small parts normally used to build docks and formwork.‎ A considerable economic advantage, which is also not negligible from an environmental point of view.‎ NPS® SYSTEM guarantees certain costs because they are fixed during the order definition phase on the basis of an operational planning that will be a reference for the entire job.‎ Furthermore, as no provisional works are required, there are no surprises of additional rental costs.‎ IN ACCORDANCE WITHLAW AND CERTIFIED All NPS® System production is in compliance with the requirements of NTC 2008 and Eurocode 4.‎ All projects are signed and stamped by a certified NPS® technician.‎ NPS® production control is certified EN 1090-1, the certification that allows the CE mark to be placed on materials.‎ To date, Tecnostrutture is the first and only Italian company to have obtained this certification.‎ Tecnostrutture and NPS® SYSTEM's strict quality requirements impose the validation of welding processes according to ISO 3834-2:2006 certification and the traceability of materials.‎ Conformity checks are conducted under the responsibility of the Technical Director of the Transformation Centre.‎ MORE SAFETY ON THE BUILDING SITE NPS® metal structures are manufactured in the factory and arrive on the building site ready for installation, directly from the truck.‎ A crane driver and two workers are all that is needed for assembly.‎ This results in labour savings of about 80 per cent compared to traditional construction systems and a reduction of auxiliary materials of about 90 per cent.‎ Thanks to the reduction in site activities, workers can devote more concentration to other site activities.‎ At the same time, the company sees a reduction in the level of training required for the workers.‎ LONGER WORK LIFE The high durability of NPS® products helps to guarantee the service life of the building - expected to be 10, 50 or 100 years, depending on the project - reducing the building's maintenance requirements and helping to keep costs down.‎ The care taken in the construction details of NPS® SYSTEM and the correct installation of the structural elements, always avoiding direct contact between the structural steel and more noble metals (such as copper, stainless steel, .‎.‎.‎), eliminate the prerequisites of electrochemical or contact corrosion (the so-called "stack effect") and guarantee the fulfilment of the durability requirements as demanded by the regulations in force.‎ SLIMMING SECTIONS NPS® SYSTEM provides more interior space thanks to its smaller footprint.‎ In the case of a garage this means more parking spaces, for an office environment thinner concrete columns with less impact on the architectural whole.‎ The slenderness of the NPS® sections makes the system suitable for use in tall buildings, ensuring a general lightening of the structure, with advantages in terms of foundations and seismic resistance.‎ SEISMIC RESISTANCE NPS® Beams and Columns guarantee both excellent static behaviour and the correct dissipative capacity required of the structure to ensure a response in the event of seismic events.‎ NPS® SYSTEM is able to function both as a seismic resistant system and as a pendulum system in compliance with all the structure factors present in the regulations in force, while maintaining the existing structure foreseen by the main designer of the work.‎ FIRERESISTANCE All NPS® products are fire resistant according to the prescriptions of Ministerial Decree 16.‎02.‎2007 without requiring any protective coating.‎ The only exceptions are Trave Iso and Lc, whose passive fire resistance is guaranteed by intumescent paints or fireproof plasters.‎ With NPS® SYSTEM, the fire resistance assessment is not limited to the individual structural element as is often the case with prefabrication, but contemplates the entire construction system with particular attention to details and possible criticalities during construction.‎ For example, a predalles slab can be calculated to resist fire for 120 minutes.‎ However, if appropriate vents are not provided in it for the overpressures generated by the gases resulting from the polystyrene melting process, the concrete overlay is ejected, leaving the reinforcement exposed with the consequent risk of early collapse.‎ ARCHITECTURAL FLEXIBILITY Even in the case of unconventional architectural and structural solutions, NPS® SYSTEM has the product that adapts to project requirements.‎ Arched beams, knee beams or even different shapes.‎ Extremely slender pillars, but with performance comparable to typical CAV pillars, such as PTC® pillars made of high-performance centrifuged concrete.‎ ECO-SUSTAINABILITY NPS® For several years, Tecnostrutture has prioritised attention to the healthiness of living spaces, launching ECOTRAVE® in 2004, the only beam on the market with a pure brick base.‎ The effort of the R&D department is to put in place products with sections that are increasingly slender and resistant, with high durability and that favour better thermal and acoustic insulation.‎ Tecnostrutture is an ordinary member of the Green Building Council Italia, an association that pursues the diffusion of Green Building through the LEED system, a protocol developed during more than ten years of experience by USGBC in the United States.‎ Evolved 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.‎ 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.‎The NPS® System is a complete and flexible modular system built of horizontal structures - NPS® Beams and NPS® Ceiling - and vertical structures - PDTI® NPS® , PTC® NPS®, and BASIC® NPS® Columns, and NPS® WALL.‎ The completely self-supported elements, produced at the plant, are mounted at the site, eliminating the need for formwork and temporary shoring.‎The composite steel-concrete product, after the cast is complete, gives rise to a mixed structure with features that adhere to the required performance level, responding to construction Standards in seismic zones as required by NTC 2008 and Eurocode 4.‎ Further info from manufacturer on NPS® SYSTEM Tecnostrutture
