LATERAL EXPANSION AND RESIDUAL LOAD CAPACITY OF REINFORCED CONCRETE MEMBERS WITHOUT TRANSVERSE REINFORCEMENT

Abstract

 Finding an index which can be abstracted from displacement field for shear failure of reinforced concrete members is an important subject for interpretation of both finite element analysis and inspection of real structures. In the present paper the displacement distribution measured from images in the variable damage stages of static loading tests was analyzed and the relationship between some indices and load capacity was investigated. Especially the expansion in the thickness direction resulted in the monotonic reduction of load capacity and tended not to be cancelled after unloading process. It was confirmed that this trend could be simulated quantitatively by finite element analysis considering material non-linearity.
