The load transfer and settlement behavior from the simulation results are also analyzed: most of the column load concentrates on the enlarged column cap, and distributes quickly, there is more load attenuation at the variable section. The skin friction of enlarged column cap develops more adequately than underside column. The column settlement concentrates on enlarged column cap, and soil settlement concentrates on a little area below the variable section.
