| Резюме≠ | The finite strip method (FSM) is a semi-analytical numerical approach for analyzing prismatic or cylindrical structures by dividing them into strips in one direction and using analytical or exact solutions in the perpendicular direction. Developed by Cheung in 1976, FSM reduces computational cost and often provides superior accuracy for structures with regular geometry along one axis. | MODFLOW is the U.S. Geological Survey's open-source, modular finite-difference model for simulating three-dimensional groundwater flow through porous media. First released in 1984 and continuously updated — most recently as MODFLOW-6 — it is the global standard for quantitative hydrogeological analysis, widely used in civil engineering, environmental consulting, water-resource management, and groundwater contamination studies. | 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. |
