Abstract

In this paper, an experimental research was conducted to study the flexural performance of the basement wall composited with a square steel tube pile used for temporary retaining wall; the inside of the square steel tube is filled with grout concrete. The stud bolts were used for the connection of RC wall and square steel tube. The thickness of wall and number of tensile reinforcing bar in the wall were set as test variables. Increasing point load was applied at the center of the wall specimens under simple support condition. The failure process of the specimens was observed during the test and their behaviors corresponding to the variables were analyzed. From the test, the basement wall composited with infilled square tube box show initial crack at 20% of peak load. The initial stiffness and maximum strength of the composite wall increased as the wall thickness and the number of reinforcing bars increased.
