The analysis of a structural system to determine the deformations and forces induced by the applied loads or the excitation of the terrain is an essential step in the design of a structure to resist the earthquake. There is a range of methods from a linear analysis to a sophisticated nonlinear analysis depending on the purpose of the analysis in the design process. In this work the seismic response of a residential building G + 10 RC is analyzed by the linear analysis approaches of Static Equivalent Lateral Force and Response Spectrum methods using the ETABS Ultimate 2015 software according to IS-1893-2002-Part-1 . These analyzes are carried out considering different seismic zones, mean soil type for all zones and for zones II and III using the OMRF frame type and for those of the rest areas using the OMRF and SMRF frame types.
When earthquakes occur, a building undergoes dynamic movement. This is because the building is subject to forces of inertia that act in the opposite direction to the acceleration of earthquake excitations. These forces of inertia, called seismic loads, are usually treated by assuming forces external to the building. Thus, apart from gravity loads, the structure will experience dominant lateral forces of considerable magnitude during earthquake quake. It is essential to estimate and specify these lateral forces on the structure to design the structure to withstand an earthquake. The ductility of a structure is the most important factors affecting its seismic performance and it has been clearly observed that reinforced and well-structured structures behave well during earthquakes and the space between the actual and design lateral force is reduced by reducing ductility in the structure.
