ABSTRACT
The relationship between the segment width and the distribution of bending stress is discussed based on the test results of six types of flat-type RC segment and FEM analyses. The results of these experiments and FEM analyses clearly show that the bending stress in the direction of width was concentrated on the edge of the specimen, and the stress concentration increased as ratio B/h increased. Based on the tests and the experience in construction, values for ratios B/h and B/D are proposed.
