NPS® Slim Sismi Column

Recommended for construction in seismic zones, the EN 1090-1 CE marked NPS® Slim Sismi Column is already seismic-resistant during the building construction.

It is equipped with an anti-seismic device pre-installed at the plant to ensure seismic resistance from the construction phase. Since it has a ductility reserve greater than reinforced concrete systems, it absorbs seismic action better, reducing stress on the structure above.

It offers high load-bearing capacities while maintaining compact cross-sections. It offers integrated fire resistance without the need for additional work on site. The NPS® Slim Sismi Column is suitable for multi-storey buildings such as hospitals, hotels, shopping centres, residential buildings as well as infrastructure.

After the placement, it is filled with concrete on site. It can be supplied in a multi-storey version, also with a different cross-section for each inter-storey. By installing a three-storey NPS® Slim Sismi Column, the vertical element for the upper two storeys is already in place - a considerable time saver.

Application-Technique Recommendations

In new buildings, earthquake-resistant steel structures with Sismi PDTI® NPS® columns improve the response to horizontal seismic actions.

They are particularly suitable in municipalities with a high seismic risk and in buildings with structural irregularities, both in plan and in elevation.

Seismic safety already in the construction phase

  • Equipped with an anti-seismic device pre-installed in the factory, the Sismi PDTI® column ensures seismic resistance already during the construction of the building.
  • The Sismi PDTI® Column has higher ductility reserves than reinforced concrete systems. It absorbs the seismic action better, reducing the stress on the structure above.

Fast return on investment

  • Reduction of the building construction time of at least 40% compared to traditional systems, ideal for new buildings or renovations.
  • Certain costs.
  • Irrelevance of weather conditions to the execution of the work.
  • Low maintenance costs.

Efficient and safe solution

  • Installation speed: 8 minutes for a multi-storey column.
  • If you install a three-storey PDTI® NPS® column, you already have the vertical element for the 2 upper storeys ready - a considerable time saving.
  • Reduction of 80% of labour requirements on site.
  • Increased safety on site.
  • Almost total elimination of props on site.
  • Delivery of beams, columns and slabs at the time of installation, without the need for storage space.

Native fire resistance

  • Native fire resistance, without the need for post installation treatments. A saving in terms of costs and time.
  • NPS® elements can also be used as visible architectural elements.

High structural flexibility

  • Maximisation of usable space in width and height thanks to pillars with compact sections.
  • Flexibility in the distribution of interior spaces, with ease of changing the layout over time.

Fewer raw materials

PDTI® NPS® Columns take advantage of the structural efficiency of combining steel and concrete. This results in compact sections with a reduced use of raw materials and optimization of living space.


Logistics with low environmental impact

Tecnostrutture adopts a logistics strategy that respects the environment. We prefer green fuel road transport or the intermodal solution with longer stretches by rail.

As shown by the analysis of the product life cycle (LCA), transport to the construction site affects 2-3% of the total life cycle. Therefore, in addition to offering solutions that have little impact on logistics, Tecnostrutture’s commitment focuses above all in the raw material supply and end-of-life management phases, those that weigh most heavily on the environmental impact of the entire product life cycle.


Reduced emissions throughout the life cycle

  • The pillars are modelled in BIM, with the lowest possible use of raw materials from the outset.
  • They are produced in the factory using both self-generated energy and - as of January 1, 2022 - energy derived entirely from renewable sources.
  • Logistics is also low emission. Tecnostrutture gives priority to green-fuel and intermodal transport.
  • Site organization is simplified thanks to the fact that fewer workers are needed for assembly: a team consists of just three fitters and a crane operator, compared to the large work teams of traditional systems.
  • Reducing on-site activities increases construction speed by an average of 40%, with positive social effects on the local community.
  • There are also advantages in relation to the drastic reduction of formwork, wood and props that are no longer necessary since the structures are self-supporting. This saves trips to bring in and return the temporary materials as well as their production. The result is a substantial contribution to the reduction of construction site waste and scrap, with NPS® products arriving ready for assembly.
  • At the end of the building's life, NPS® elements are removed through selective demolition, which allows for the reuse of the steel and concrete used.
