Conducted by one of the most advanced Universities in the world for testing dynamic structural response and at the forefront of seismic research on August 12, 2014 at the Structural Engineering Laboratoryin Bogazici (Bosphorus) University, Istanbul, Turkey
in co-operation with
GOHLER Limited – London
The first part were the dynamic tests where, in addition to ambient vibration measurements, the structure was dynamically loaded via an eccentric mass shaker located on top of the building (i.e. forced vibration test).
The second part of the experiment comprised of cyclic tests where the structure was pushed and pulled from side to side via actuators located on the 1st and 2nd floor levels.
This was to determine key parameters to be used in seismic design of future buildings such as lateral load bearing capacity and ductility.
The inter-storey drift at the yield point was measured to be around 2%, therefore the ductility of the structure is extremely high and it can take approximately twice the displacement of an ordinary reinforced concrete structurebefore failure underearthquake conditions.
Not withstanding the anchors pulled out and the building was displaced at 53mm displacement at the 1st floor level,
OUR material was intact and no significant cracks were observed on the building.
When the actuator piston reached its full stroke at 100mm (this is an unrealistically high displacement which will not occur in any real earthquake) at the 1st floor level,
Significant cracks occurred on the walls but there was no collapse of any critical member in the building.
Meaning that the building would remain standing with cracks and the inhabitants presumably remaining unharmed inside.
Again, the initial analysis shows that the addition of our invented materials increases the loadbearing capacity of the steel structure by approximately
4 times (400%).
