Description

Background

Earthquake is a natural disaster with huge destructive power, can cause great life and property loss, and if effective measures can be taken, the dynamic response of the structure caused by earthquake motion can be reduced, the structural damage caused by earthquake can be effectively reduced, a large amount of cost for earthquake resistance is optimized, and the life and property loss is reduced.

The existing demonstration model for simulating the deformation of the building by different seismic waveforms is relatively short, and the field simulation teaching demonstration cannot be carried out, so that the problem is solved by a demonstration model for simulating the deformation of the building by different seismic waveforms.

There are two main categories of seismic waves propagating in the earth: solid waves and surface waves. Waves that travel through the earth's interior are solid waves. Solid waves can be divided into longitudinal waves (P-waves) and transverse waves (S-waves). The longitudinal wave is the propulsion wave, the propagation speed in the crust is 5.5-7 km/s, the speed is the fastest, and the longitudinal wave is the first seismic wave, also called P wave, which makes the ground vibrate up and down and has weaker destructiveness. Shear waves are shear waves: the propagation speed in the crust is 3.2-4.0 km/S, which is the second seismic wave reaching the seismograph, also called S wave, which makes the ground shake back and forth and left and right, and the destructiveness is strong. Waves whose propagation is confined to the earth's surface or interface are surface waves. Surface waves can be classified into love waves, rayleigh waves, and the like. The propagation speed of the surface wave is slowest in three seismic waves, but the vibration amplitude is far larger than that of P waves and S waves, and the ground vibration caused by the surface wave is larger than that caused by the solid waves, so that the damage is the strongest. Therefore, surface waves cause greater damage than solid waves.
