Nowadays, reducing on-site construction period is a major issue in Japan. Since joining of structural members is always conducted on-site, reducing joint parts contributes to a reduction of on-site construction period. This study examines a new joint structure of Steel Earth-Retaining Beams (SERBs) used during excavation work. Many bolts are used in a connection of SERBs. To reduce the number of bolts in SERBs while reusing the existing SERBs, this study developed ductile cast iron components which are installed SERB connections with FE analysis. Particular, we proposed the shape of the ductile cast iron components to improve the joint strength performance, and clarified the applicability of the cast iron parts in the SERB connection.
