The advantages offered by Holedeck makes it the optimum structural system for high-rise buildings:
- It allows a reduction of up to 20% of the total built volume. One floor can be obtained for each 5 floors, and it can significantly increase the floor area for the same volume.
- Total built height can be decreased maintaining the same number of floors. This means savings of 10 to 20 % in façade and interior partitions , and a reduction of 10 and 20 % at pillars and / or load bearing walls.
- Also, height clearance can be increased up to 50 cm per floor without affecting the total built height. Entire items, such as ceiling and / or technical floor, can be deleted. Services can be placed directly on the ribs of Holedeck slab, without the need of a fastening system.
Behaviour against horizontal stress
Holedeck solves horizontal diaphragms for high-rise structures. It provides higher stiffness for the same weight compared to a solid slab or a traditional waffle slab, decreasing buckling risk.
It combines a monolithic behaviour in every direction with a reduced self-weight, which means less inertial stress for seismic prevention, and savings on dimension and structure reinforcement against horizontal stress.
When combining the Holedeck slab with any conventional seismic-stress prevention system (core, walls, cross beam), or with any ground-breaking technology (seismic dumpers) , high rise buildings can achieve seismic-proof structures, at different performance levels.
