The stiffness of the panel of a connection between beam and olumn can have a significant effect on the deformation behaviours of the frame. And the paned is assumed not to deform in shear because of the presence of the intersection beam. But shear crack can be seen in a panel zone of the reinforced concrete specimen. Although the intersection beam makes the panel zone rigid, the degree of rigidity depends on the scale of the intersection beam and the shear-span ratios of beam and column, respectivery. Accordingly, the object of this paper is to make clear the relations between the scale of intersection beam and the rigidity of the panel zone. In attempting to deal with the above problem, elastic experiment by photo-elasticity and measuring the diagonal distances were adopted.
