This paper proposes the new measuring method for a normal compressive stress distribution in concrete members by using a symmetry of geometry and loading pattern. This method would have the ability to develop effectively a constitutive model for concrete in an inelastic-finite element analysis, based on a compressive stress distribution measured in concrete members. Besides to observe precisely ever-unknown compressive stress distribution in concrete members. For a verification of that method, a study was conducted with experiment and analysis. In the experimental part of the study, tests were conducted adopting it to concrete cylinders subjected to uniaxial compression, and an inevitable probrem in measuring is verified, based on the results of failure, average compressive stress-strain curve and poisson's strain. In the analytical part, the inevitable probrem is verified, based on the results of an inelastic-finite element analysis. The results indicate the validity of the measuring method.
