By means of the two-dimensional reflective photoelastic method, the authors have investigated the influence of the rigidity of member on the stress concentration factor (scf.) at the reentrant corner of triangular rib, when the members were intersected at right angle and subjected to pure bending. The results obtained were as follows : 1) Under a given geometry of rib, the great increase of scf. was recognized with increasing rigidity of member. When the rigidity of member becomes three times of that in 1st report, it is desirable to increase the rib thickness or the number of ribs so as to reduce the scf. 2) The ratio of maximum stresses at the reentrant corner, γ, was introduced for the case where the same bending moment was applied to the member having various rigidities. γ did not change considerably in the high rigidity, so that the scfs. for untested range of high rigidity might be estimated from this γ.
