Abstract
The author's answers to the discussion by Prof. Takiguchi are as follows. (1) What do the authors evaluate the previous paper? There have been no investigations in which the strain distributions of concrete were discussed on the basis of the measured values of the strain. (2) Are there physical meanings of flexural and shear deformation components? Up to the maximum load, the physical meanings of the deformation components exist. However, after the propagation of the diagonal shear crack, there exist no physical meanings in the deformation components. (3) "Linear strain distribution" does not exist in the test beams. In each section, the maximum value of compressive strain was observed at the compressive fiber. The values of the compressive strains decrease with the distance from the compressive fiber. The authors expressed this tendency as "linear strain distribution". However, in the tensile side this tendency did not observed. (4) Eq. (3) and the linear strain distribution are not established simultaneously. The authors agree with this advice. However, shear stresses in beams have been calculated by using the flexural stresses based on the linear strain distribution. The shear stresses thus derived have sufficient accuracy.
