This paper deals with analyses of aluminum poles for reinforcement of old or weak wooden houses due to static lateral loading test. Three-dimensional elasto-plastic Finite Element Method (FEM) analyses were carried out to examine whether the computer analysis could accurately simulate or not results for the elasto-plastic behaviors of aluminum columns buried in soils with different embedment depths due to laterally loading tests. The behaviors were simulated fairly precisely by the elasto-plastic FEM. In addition, impact analyses were made for the horizontal load tests for aluminum poles with actual size buried in a soil to examine the applicability of the three-dimensional FEM. In consequence, the impact behaviors of the aluminum column could be found in consideration of the elasto-plastic interaction between aluminum column and soil.
