This experimental study analyzed the reduction of the load capacity of the system support according to the uninstall bracing members by loading the ultimate load to the 3 - story system support assembly with the presence of bracing members as the key parameter. The load capacity of the 3-story specimen without bracing members is 38.4% of that of the 3-story specimen with bracing members. It is necessary to accurately reflect the installation plan of the bracing members and examine the structural safety of the system support assembly, not a single member, because there is a significant decrease in the load capacity of the system support assembly according to the uninstall of the bracing members.
