Parametric analyses of steel poles for reinforcement of old or weak wooden houses subjected to impact loads were conducted using tree-dimensional elasto-plastic FEM. Parameters were (1) soil classification; cohesive soil, sandy soil, (2) shear wave velocity; 100, 125, 150m/s, (3) embedment depth; 1.25, 1.50, 1.75m. Furthermore, load-displacement relationship of steel poles buried in cohesive and sandy soils were determined using the impact response analyses based on the energy preservation, that is, complete transformation of motion energy of impacting body into strain energy of pole.
