DAMAGE ESTIMATION OF UNDERGROUND RC-STRUCTURE SUBJECTED TO BEDROCK DISPLACEMENT CONSIDERING BOND PROPERTIES BETWEEN STRUCTURE AND BEDROCK

Abstract

 This research is focused on the damage estimation of the underground reinforced concrete structure placed on the fault line in case of the fault rapture. Bond properties between the structure and bedrock are considered as a contribute factor which can have an effect on the damage process, fracture modes, and the limit fault dislocations.
 Three-dimensional nonlinear FE analyses were performed to investigate behavior of underground RC culvert using bond properties derived from bond strength tests. These analyses showed that the stiffness of bedrock and the friction force had an effect on them, on the other hand, bond strength had a small effect.
