We pursue innovative construction technology that finds a path for local coexistence by optimizing environment-based plant facilities that are treated only as resident-hating facilities and constructing them underground and providing the upper space as resident-friendly facilities. In this study, a study was conducted on the safety when installing an underground complex plant composed of only section steel. In consideration of the area of the underground space and the devices arranged, the spacing of the columns was set to 10m in width and length, and braces were also modeled and performed to distribute the self-load on the material. As the boundary conditions, the conformity of the standard was confirmed through the structural analysis results applying the device load, self load, earth pressure, and earthquake load. As a result, in Cases 1 and 2, the same sag phenomenon occurred due to the fixed load, but in case 3, it was confirmed that the sag phenomenon occurred in the brace as the fixed load was distributed to the brace. SM460 was selected as the applied material, and the analysis result confirmed that design is possible stably. Using this analysis method, it is believed that it can be used as basic data when designing an underground complex exterior frame.
