Abstract

The steel pipe attachment method has been employed as a seismic strengthening technique for RC columns in cut and cover tunnels. In this method, two concrete-filled tubular steel columns are attached to the RC column from both sides, and they will prevent the, tunnel from collapse even if the RC columns undergo shearing failure. In order to appreciate the mechanical properties of the attached column, numerical analyses are accomplished. This paper presents the modeling of the RC and attached columns and then constructs an interaction analysis method. Several discussions are carried out through comparison between the numerical and the experimental results.
