Most regions in Indonesia have the potential for earthquakes, including Mandailing. Traditional wooden house of Mandailing was established without the expertise of an engineer and architect. The aim of the study was to identify the wooden structures against seismicity to obtain an efficient and contextual wood construction for earthquakes. Therefore, it is important to observe and analyse the structure of buildings through seismic approaches and alternative solutions to the sustainability of construction. The research method was an experimental using SAP2000 simulations. It was to identify the performance of columns and beams as the main structures that require reinforcement and experience friction. The data analysis showed that the building had a mass of 355.484 kN with a static shear force of 150.0142 kN and a dynamic shear force of 693.274 kN, while the vibrating period of the Mandailing traditional wooden houses structure had a T = 0.94267 seconds value. In other words, the SAP2000 modelling results illustrate that the displacement which occurs in buildings with an earthquake scale factor of 10 is still within the safety limits. Thus, the buildings are flexible to earthquake movements, and damages in the buildings can be minimized.
