This research, is based on the analysis of field data as well as existing models of hypothetical tsunamis caused by the Makran fault under different scenarios, introduced forces on coastal residential structures, taking into account the depth of penetration and altitude of the tsunami flood in the Chabahar area. Also, considering the land cover of the area, the stability of the residential structure of the sample was examined with the frame of a floor using the SAP2000 software. Since a structure is exerted against linear forces from the forces flowing from a tsunami, a nonlinear static analysis was used. In this study, existing residential buildings in the region were examined in such a way that the possible advance of the expected tsunami was anticipated to propose the most secure structures. Also, the probable flooding of Chabahar, the largest population center and coastal facility in the north of the Oman Sea, was assessed which was based on the simulation and numerical modeling of pre-assumed tsunami in the area. The results indicated that, in the case of a single-story structure, according to the thesample, up to a displacement of 0.6 cm for a base cut, about 55 tons behaves almost linearly. The structure moves into the destruction area after moving 1.55 cm. In a building with a two-story frame, the absence of walls resistant to hydrodynamic forces and the wave fracture force will be much less because the width of the column in front of the flow is much smaller than the width of the wall, which is equal to the total width of the frame. That is why the amount of these forces is greatly reduced.
