ANALYSIS OF STATIC LATERAL LOADING TEST OF ALUMINUM POLE BURIED IN SOIL(Structure)

Abstract

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.
