On seismic response of loess-mudstone slope with …
In this study, we conducted a laboratory investigation using a shaking table test on LMS with an ADFZ and compared the effect of ADFZ with BDFZ. The typical acceleration response is that the acceleration amplification factor (AAF) increases from the bottom to the top of the LMS surface and is larger in loess than in mudstone.

Shaking Things Up in the Classroom
Grab yourself a flexible ruler, clamp one end of it on the edge of a table (yes, like a cantilever beam) and flick the other end. That momentary flick will cause the ruler to vibrate at some frequency. Adjust the length of the ruler and flick it again. You'll notice that it vibrates at a different frequency! Buildings vibrate in a similar way ...

Shaking Table Tests on Sliding Displacements of Loess Slope
Shaking table tests were performed to investigate whether the coupling effect of rainfall and earthquake induces the loess slope instability. The loess slope model was made by using the similarity ratio based on a real slope. Artificial rainfall was carried out, and then seismic waves were loaded step by step to adopt a large shaking table of …
