Description The revolutionary SPIDER system makes it possible to create timber skyscrapers with a column-to-floor system, eliminating all the beams. The steel core of the system prevents the CLT panels from being crushed and allows more than 5,000 kN of vertical load to be transferred between the columns. The arms of the system ensure the punching shear reinforcement of the CLT panels, allowing exceptional shear strength values. SPIDER offers the possibility to create free spans higher than 7.0 x 7.0 m even without special connections between panels. In addition to multi-storey buildings, SPIDER opens new architectural horizons, making it possible to create structures with large spaces, a reduced number of columns and large windows.
