Recently, in the modularization method, a technique of installing a module by reducing a floor area and stacking is introduced. Structural frame stacking structure design should take into consideration the concentrated load site according to the center of gravity depending on the wind speed and the shape of the equipment. In this study, structural analysis of stacked modules was conducted to reduce construction period and improve space layout when installing plants in cold and harsh areas. For analysis, the FWKO (free knock out drum) module and the pipe rack module, which constitute the oil sand plant, were selected. Applied materials are based on ASTM (American Society for Testing Materials) A36, A572, and compared domestic materials with yield strength and tensile strength. Structural analysis using wind load, dynamic load, and device load condition as boundary condition was used to determine the suitability of the standard and the appropriate cross-sectional size. The position of the center of gravity varies according to the wind speed and the shape of the equipment in the design of the stacked structure frame. Therefore, it is important to determine the H beam size in consideration of the concentrated load site. In addition, it was evaluated that stable stacking design was possible as a result of analysis with domestic materials SS400 and SM490. Such analysis method, load condition, domestic material and transportation standard can be used as basic data in designing structural frame.
