Strain softening of concrete in uniaxial compression critically m1:1uenc:;es way concrete structures are designed. Yet it is not explicitly included design methodologies. This may be partly due to the fact that it is difficult to obtain post-peak pesponse especially for higher strength concrete and that the response depends also on the geometry of specimens, boundary conditions, and testing machine parameters. To delineate the influence of various parameters, a round robin test program is being persued by .L-..JL.LJ.._,,.. Committee 148 SSC 'Strain Softening of Concrete.' Results obtained from one laboratory participating in this round robin test program are discussed. discussion includes methods to obtain the strain softening response of concrete in compression. The effects that the platens, lubrication between platens specimen, specimen size, and measurement gage length have on results are explored.
