Abstract

The vertical loads of a structure are usually carried by pile foundations, but horizontal loads are dominant in some other structures. It is, however, necessary to note that combined loads are seldomly analyzed in simultaneity even though they work simultaneously on-site. This means the horizontal movement added due to the combined loads is not usually considered in construction. Therefore, this research was conducted to investigate and analyze the effect of combined loads at horizontal movement on a single pile and group pile foundations. The process was in three stages. The first was an analysis conducted through 2D-FEM Plaxis2D8.6, the second was an experimental test in the laboratory, and the third involved the analysis through 3D-FEM Plaxis3D Foundation1.1 for validation using soil data and loading test on several projects. The results showed the horizontal movement increased significantly up to the moment it averagely collapsed after reaching ((Pu.D)/(Hu. L.E)=2.5x10-6) for a single pile and ((Pu.D)/(Hu.L.E)=0.745x10-6) for group pile. This increment needs to be considered in the construction process and the additional horizontal movement due to the combined load also needs to be considered after the limits have been reached.
