This study reports the experimental verification of the reinforcing effect of the open web type SRC beam-column joints strengthened by additional members on one side. In strengthened specimens, RC members were added to one side of the existing SRC beam-column joints and beams, and the additional members and existing beam-column joints were prestressed in the horizontal direction with PC rods to reinforce them. From the test results, strengthened specimens were able to suppress cracks and shear deformation at the beam-column joints. The maximum story shear force can be evaluated by the equations shown in various standards.
