From 2.45 minutes to 2.50 minutes in 5 seconds makes 10 complete oscillations of 44 cm .... so made ​​at 20 sec 40 oscillations of 44 cm

1) my model , at high speed , hit 40 complete oscillations in 20 sec. This means that the oscillation frequency is : n = 40/20 = 2Hz ( revolutions / sec) and the period T = 1 / n = 0,50 sec.
2) 11 cm radius of rotation in the order of conversion of rotary motion into a reciprocating , the maximum horizontal speed succeeded to the one or other direction , is : U = 2p.r.n = 138,16 cm / sec.
3 ) This velocity , which starts from zero at both ends, is obtained in the halfway of 22cm, i.e. at time T / 4. So the horizontal acceleration of my model is : a = h / ( T / 4 ) = 4u / T = 4 * 138,16 / 0,50 = 1105,28 cm/sec2 = 1105,28 / 981 = 1,13 g
And the vertical acceleration of 0,06 g
Full acceleration Got horizontally 1,13 g
Full acceleration is perpendicular succeeded 0,06 g
Experiment with speed 8 g!
The actual physical acceleration of the earthquake is one that I mentioned above too .
But because the model is in the range 1 to 7.14 to see the actual intensity earthquake would have if the model were true scale must be multiplied by the radius rx 7.14 scale at which the model was constructed .
Specifically ...
In the experiment this model makes ...
From 2.45 minutes to 2.50 minutes in 5 seconds makes 10 complete oscillations so .... 20 sec at 40 oscillations made

2) rotation radius 11 cm x 7,14 in the range of the conversion means into a reciprocating rotary motion , the maximum horizontal speed succeeded to the one or other direction , is : U = 2p.r.n = 987 cm / sec .
3 ) This velocity , which starts from zero at both ends, obtained midway i.e. at time T / 4. So the horizontal acceleration of my model is : a = h / ( T / 4 ) = 4u / T = 4 * 987/0, 50 = 7896cm/sec2 = 7896/981 = 8g
And the vertical acceleration 0,43 g
Full acceleration Succeed natural size structure is horizontally 8g
Full acceleration is perpendicular succeeded 0,43 g
The behavior of the model was without faults in the experiment , and therefore we do not know further strength.
The buildings in Kefalonia manufactured with the highest rate of seismicity in Greece that is 0,36 g.
Although withstood much more 0,50 - 0,60 g reaching the acceleration in this earthquake .
Anyway , my design model far exceeded the value of g currently planned .
