FORCED VIBRATION OF FULL-SCALE WALL-BACKFILL SYSTEM

Investigators conducted a full-scale vibration test to measure the low-amplitude dynamic characteristics of a reinforced concrete cantilever wall-backfill system. Measurements were recorded during a frequency sweep along the wall length. Resonant frequencies were identified from these measurements, along with the corresponding response configurations that depict variation in motion along the wall length. Generally, the wall and adjacent backfill zone move together in-phase. Farther away from the wall, out-of-phase wall-backfill motions were measured at higher resonant frequencies. Also, retaining systems of uneven height, such as wing walls, display three-dimensional seismic response characteristics.
