Abstract: Earthquake is the result of sudden release of energy from epicenter in the earth’s crust that generates seismic waves action. It has social as well as economic consequences such as causing death and injury of lives especially human beings and damages the buildings and natural environment. Ground shaking and rupture are the major effects generated by earthquakes.In order to take precaution for the loss of life and damage of structures due to the ground motion, it is important to understand the characteristics of the ground motion. The most important dynamic characteristics of earthquake are peak ground acceleration (PGA), duration, and frequency content. These characteristics play dominant rule in studying the responses of structures under seismic loads. The time history analysis begins by selecting an appropriate ground motion record that represents the seismic input to the structure. The ground motion record is typically obtained from historical earthquake data or synthesized based on specific design criteria. Once the ground motion record is obtained, it is applied to the building model as an input motion. The analysis results are then evaluated against performance criteria and design codes to ensure that the building meets the required safety standards. Engineers can use the analysis outputs to assess the structural integrity, identify potential weaknesses, and make necessary design modifications to enhance the building's seismic performance. Time history analysis plays a crucial role in assessing the seismic performance of buildings. It provides valuable insights into the dynamic behavior of structures and aids in designing safer and more resilient buildings.
