The authors have studied the stress concentration at the reentrant corner of trapezoidal rib under pure bending by the two dimensional photoelastic method. Thus the influence of the fillet radius at the reentrant corner, the thickness of member and the height of rib on the stress concentration factor were clarified. The results obtained were as follows : (1) the stress concentration factor decreased gradually with the increase of height of rib so long as the height was relatively large, and the stress concentration factor decreased drastically when the height of rib became small. (2) The stress arised in the rib increased with the decrease of height of rib. Below a certain height, the maximum stress in the rib exceeded the one at the reentrant corner of rib. This critical height of rib increased as the fillet radius or the thickness of member increased.
