EVALUATION OF BENDING FRACTURE CHARACTERISTICS OF STEEL SHEET PILE - CONCRETE COMPOSITE BY AE ANALYSIS

Abstract

In recent years, the accelerated corrosion of steel sheet pile in an agricultural canal has been problems. In this research, evaluation of bending characteristics is conducted in corroded steel sheet pile with concrete coating by using AE and DICM. The test specimens are made of three-layer composite which is composed of steel sheet pile, concrete and precast panel. Thus, the deformation behavior of testing samples could be evaluated by AE and DICM parameters. A relation between torsional behavior due to the concavo-convex shape of steel sheet pile and bending behavior of composite was correlated.
