ABSTRACT
Earthquakes are natural disasters that pose significant threats to buildings and human life, particularly in regions prone to seismic activity. The impact of such events on structural integrity makes it crucial to design buildings capable of withstanding seismic forces. In this context, dynamic analysis plays a vital role in evaluating a building’s ability to resist earthquakes. The study presented here employs SAP 2000 software to perform seismic and response spectrum analyses on multi-story buildings. Three different architectural plans square, C-shaped, and L-shaped are considered for the analysis, using IS 456 and IS 1893-2002 seismic codes. The comparison of base shear, storey displacement, storey drift, and storey stiffness under seismic and response spectrum conditions helps in understanding how these factors affect the building’s performance during an earthquake. The primary goal of this analysis is to reduce base shear and improve storey stiffness, thus enhancing the overall seismic resilience of the buildings.
In recent years, structural dampers, particularly visco-elastic dampers, have gained popularity in building designs to mitigate the effects of seismic forces. These dampers help prevent excessive diagonal movements and cracking of buildings during an earthquake, thereby ensuring the safety and stability of the structure. In the present work, the effectiveness of visco-elastic dampers is analyzed by comparing buildings with and without dampers. The study aims to demonstrate how the inclusion of such dampers improves the building’s response to seismic activity, leading to reduced lateral displacements and structural damage. By integrating these dampers into the three different building shapes, the research provides insights into optimizing structural performance in earthquake-prone areas, contributing to safer and more resilient buildings.
