Multiaxial strain-softening of concrete
Abstract The paper describes the behaviour of concrete specimens (cubes, d=100mm) subjected to multiaxial cyclic and rotation load paths. The specimens were loaded in a recently developed multiaxial apparatus which was described shortly in Part I. A cyclic load path corresponds to a series of loading-unloading cycles to the envelope curve, for which the major compressive stress-strain curve was used for defining the unloading conditions. The rotation paths implied a simple exchange of major and minor compressive stress, after some damage was sustained to a specimen. The observed stress-strain behaviour of the different loading paths was discussed in relation to the “final structure” of a specimen subjected to multiaxial compression. The “final structure” consists of a number of more or less intact rest pieces, separated by localised shear zones. The movement of the blocks with respect to each other and into the shear localisations seems to determine the complete observed response. By using cyclic and rotation load paths, the geometry and frictional characteristics of the shear fractures may be determined.
