Seismic Analysis of G+8 Building with Advanced Software Modelling Techniques

Abstract

Seismic analysis plays a vital role in ensuring the structural stability and safety of buildings subjected to earthquake forces. This study focuses on the seismic analysis of a G+8 (Ground + 8 stories) building using advanced software modeling techniques. The objective is to evaluate the building’s response under seismic loading conditions and propose effective design enhancements to improve earthquake resistance. In this research, finite element modeling (FEM) and dynamic analysis techniques, including Response Spectrum Analysis (RSA) and Time History Analysis (THA), are implemented using advanced structural analysis software such as ETABS, STAAD.Pro, and SAP2000. The study examines critical seismic performance parameters such as story displacement, inter-story drift, base shear, and fundamental time period. Additionally, different structural configurations, including shear walls, bracings, and dual systems, are analyzed to optimize seismic resistance. The findings indicate that implementing seismic-resistant design strategies, such as ductility enhancement, optimal member placement, and base isolation techniques, significantly enhances structural performance under earthquake loads. This study highlights the effectiveness of advanced software tools in seismic analysis, providing engineers with a cost-effective, accurate, and efficient approach to designing earthquake-resistant structures while ensuring compliance with seismic codes and sustainability principles.
