Earthquakes engineering testing methods

We define below some common terms in earthquake engineering to clarify test requirements and methods ... 

Now that it is possible to establish test facilities in a laboratory to simulate the time history of an earthquake seismic tests are conducted by creating the ground movements in the test object. Other methods, such as by analysis or by combined analysis and testing, are also available. Refer to IEEE 344 and lEC 60980 for more details. For this purpose a shake table, able to simulate the required seismic conditions (RRS) is developed on which the test object is mounted and its performance observed under the required shock conditions. Since it is not easy to create such conditions in a laboratory, there are only a few of these facilities available. The better equipped laboratories are in Japan, the USA, the UK, Greece, Germany, India and China. In India the Earthquake Engineering Department (EQD) of the University of Roorkee (UoR) is equipped with these facilities.

Maximum shear modulus of soil (G ) is the fundamental property of the soil in geotechnical earthquake engineering application. The most reliable methods to determine the maximum shear modulus of soil are those conducted in the field. This is because the laboratory soil testing of undisturbed soil samples is often subjected to errors due to sample disturbance. Evenifthe disturbance is minor in advanced technique of sampling, time and expense may be substantial. Hence in the present study shear wave velocity obtained from the cross hole test is utilized to compute the maximinn shear modulus of the soil using the formula discussed earlier.
