3D SEISMIC TEST

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%).
