Summary:Abstract Steel tubular pile technology is an effective method to reinforced foundation in retrofitting of existing buildings. Mirco-steel tubular pile is constructed with concrete filled steel tubular, the infilled concrete could reinforced the strength of mirco-pile and prevented the local-buckling of steel tubular. According to ANSYS software, a mode of finite element analysis was built with some function between mirco-pile and soil foundation, the mode was confirmed by some test data. The slenderness ratio and material strength were two important factors for the bearing capability of mirco-pile with concrete filled steel tubular. The bearing capability and some influence factors on concrete filled mirco-steel tubular piles were analyzed by factors analysis method. The mode of finite element analysis and factors analysis method on were applied for reinforced building foundation and referred to other application of concrete filled steel tubular.
