In the design of multi-storey frame structures, there is a question of a proper evaluation of the stiffness of reinforced concrete frame joints. This problem is very important especially in the case of structures subjected to seismic load, where the forces act repeatedly. Concrete is able to carry the compression stresses and partially the shear stresses. The tension stresses can reach only low level. The maximum tension stresses (tension strength) obtained from simple tension test of the concrete are not the same as the maximum tension stresses in the reinforced concrete. The shear stiffness is the matter of the width of the concrete cracks. To improve the knowledge in this field, the experimental verification of the reinforced concrete frame joint had been arranged.
