Column PDTI® NPS®
Mixed steel-concrete beam and column
Recommended for construction in seismic zones, and to make the best use of space thanks to the compactness of sections with the same required performance, for structure ductility and beam-column node confining. It is suitable for infrastructure, major projects, and just as it is for residential buildings.The NPS® PDTI® transverse expansion stopping column is comprised of metal profiles with circular, square ore rectangular sections, usually filled with concrete. It joins the versatility of a metal structure in the provisional phase with the resistance of a mixed steel-concrete structure in the working phase. It can be supplied with helical or vertical welding, and if requested in a multi-storey version, even with a differentiated section for each interfloor. Metal structure: S275/S355 structural steel sleeve conforming to Standard UNI EN 10219-1. Beyond representing formwork for the casting formwork, it also comprises a hoop system around the central, internal concrete, increasing total resistance.
