The large spatial structure is three-dimensionally arranged on the basis of the three-dimensional force flow, so it has excellent performance and efficiency, enabling the design of a column-free large spatial structure. The space frame structure is a typical large spatial structure, and it has a high rigidity and is affected by earthquake loads more than wind loads. That is safer to earthquakes than general structures can accommodate many people and are used as evacuation spaces. However, there are often cases where structures are damaged due to strong earthquakes and objects cannot be used for their intended purpose due to falling objects. Based on such cases, the need for earthquake response control research for large spatial structures is also raised. Therefore, in this study, we intend to analyze the seismic response according to the number of installations, positions and masses by applying the tuned mass damper, which is a representative vibration control device with a simple principle, to simple generalized large spatial structures.
