220.00 connector studs
In the construction of the “Puerta de Europa” inclined towers in Madrid, two parallel assembly teams were used, one in each tower, which made it possible to follow the assembly rhythm at all times.
The mixed beam consists of three elements: steel beam; reinforced concrete slab; and connector studs welded to the beam. The bolts absorb the shear stresses between the beam and the concrete slab, causing both to act as a single element. The strength and stiffness of the effective section can be increased without the need to use larger beams for a given load.
The mixed construction system saves tons of steel, reduces the height of the building to be built and saves on materials, since by using lighter beams (less holy), plants with smaller sections are obtained, which allows larger rooms with fewer obstructions as they can be built with greater spacing between pillars.
