Building structure planning is an important aspect in building construction, especially in multi-storey buildings such as 2-story houses. Good structural planning is needed so that buildings are able to withstand various types of working loads, such as dead loads, live loads and earthquake loads. The West Lombok Regency area on Lombok Island is an area that has the potential for earthquake activity, so building structure planning must pay attention to aspects of earthquake resistance. Therefore, proper structural analysis is needed to ensure the safety and stability of the building. This research aims to analyze the structure of a 2-story house in a housing complex built by PT. Tunas Jaya Masterpiece is located in Sedayu Hamlet, Kuripan Village, Kuripan District, West Lombok Regency. Structural analysis was carried out with the help of ETABS version 19 software to determine the structural response to various types of loads acting on the building. The research method used is the structural analysis method with building modeling using ETABS software. The analysis results obtained include a bending moment of 14.94 kNm, a shear force of 97 kN, an axial force of 247.76 kN, and Storey drift (floor drift) is still safe and smaller than the permitted stirey drift. Based on the results of the analysis carried out, it was found that the structure of the two-story house was able to withstand the working loads and met structural safety requirements in accordance with applicable planning provisions. Thus, the building structure is considered quite safe and suitable for use as a residential building.
