Self-supporting structure

If you want to save cost, you can design a building avoiding the construction of the last forged floor. We recommend to use the self supporting structures. In this case the zone under the roof is non habitable but the structural cost reduction is big.

This system uses I, 2C and ST sections and it eliminates the central pillars, which provides large span spaces.
In the drawing you can see an example of roof truss of this structuralsystem.
