| Résumé≠ | Terzaghi consolidation theory describes how water-saturated clay soils compress over time as excess pore water pressure dissipates and effective stress increases. Formulated by Karl Terzaghi in 1943, this foundational theory enables prediction of settlement rates for foundations on compressible soils, a critical design concern in geotechnical engineering. | Soil-structure interaction (SSI) analysis accounts for the dynamic coupling between a structure and its supporting foundation soil, recognizing that the soil is not infinitely rigid. Formalized by Veletsos in 1974, this approach reveals how foundation compliance, radiation damping, and kinematic effects modify the structure's seismic response compared to fixed-base assumptions. |
