Experience in past earthquakes has demonstrated that many common buildings and typical methods of construction lack basic resistance to earthquake forces. In most cases this resistance can be achieved by following simple, inexpensive principles of good building construction practice. Apart from gravity loads, the structure will experience dominant lateral forces of considerable magnitude during earthquake shaking. It is essential to estimate and specify these lateral forces on the structure in order to design the structure to resist an earthquake. It is impossible to exactly determine the earthquake induced lateral forces that are expected to act on the structure during its lifetime. However, considering the consequential effects of earthquake due to eventual failure of the structure, it is important to estimate these forces in a rational and realistic manner. In this study,equivalent static force analysis procedure as per IS 1893(PART I) for four storey RCC building is been carried out and theoretical results are compared with modeling of building in STAAD Pro software .

An earthquake is the vibration, sometimes violent to the earth¿s surface that follows a release of energy in the earth¿s crust. This energy can be generated by a sudden dislocation of segments of the crust, by a volcanic eruption or even by a manmade explosion. The dislocation of the crust causes most destructive earthquakes. The crust may first bend and then the stresses exceed the strength of rocks, they break. In the process of breaking,vibrations called seismic waves are generated. These waves travel outward from the source ofthe earthquake along the surface and through the earth at varying speeds depending on thematerial through which they move. These waves can cause disasters on the earth¿s surface.No structure on the planet can be constructed 100% earthquake proof; only its resistance toearthquake can be increased. Treatment is required to be given depending on the zone inwhich the particular site is located. Earthquake occurred in the recent past have raised variousissues and have forced us to think about the disaster management. It has become essential tothink right from planning stage to completion stage of a structure to avoid failure or tominimize the loss of property.
