SP EARTHQUAKE SIMULATION SYSTEM WITH EARTHQUAKE REAPPEARANCE DEVICE FOR PRIMARY WAVE AND SENCONDARY WAVE AND VIBRATION DEVICE FOR NATURAL FREQUENCY WAVE OF EARTHQUAKE TEST OBJECTS

摘要

The present invention relates to an earthquake emulating system capable of reproducing seismic waves including S-wave and P-wave and excitation of a natural frequency of earthquake target building, which independently applies vibrations by P-wave and S-wave, which are body waves among seismic waves, to reproduce an earthquake close to the body waves that S-wave reaches after P-wave, and at the same time, performs excitation with a natural frequency of an earthquake target building. The system comprises: a base plate (10); a P-wave vibrating plate (20) which is installed to be able to move back and forth on the base plate (10); an S-wave vibrating plate (30) which is installed to be able to move like a see-saw on the P-wave vibrating plate (20); a P-wave implementing device (40) which is installed in the base plate (10) and applies a P-wave vibration to the P-wave vibrating plate (20); an S-wave implementing device (50) which is installed in the P-wave vibrating plate (20) and applies an S-wave vibration to the S-wave vibrating plate (30); and a self-vibrating implementing device (70) which applies vibration to an earthquake experimenting body (100) which is put on the S-wave vibrating plate (30) or fixed to the same.
