THE STRESS-STRAIN BEHAVIOUR OF CONCRETE IN THE COMPRESSION ZONE OF FLEXURAL MEMBERS

To investigate more deeply the differences between the compression zone of flexural members, flexural and compression tests of primatic specimens as well as compression tests of control cylinders were carried out for a wide range of strengths of normal-weight and all- lightweight concrete. It was found that high strength concrete, especially all-lightweight concrete, is likely to rupture in conventional compression tests of cylinders at a stressless than the peak stress of the stress-strain curve for flexure. Though the shape of the stress-strain curve for flexure was sensitively affected by the length of strain measurement, the peak of the flexural curve was found to be at a higher stress and at a larger strain than the peak of the concentric compression curve of the prismatic specimens. /Author/
