Comparative Analysis Of G+5 Multi Storied School Building for Different Seismic Zones Of Bangladesh

Abstract

The Bangladesh National Building Code (BNBC) outlines and governs the fundamental specifications for structural, architectural, and design standards within Bangladesh. Over the past thirty years, advancements in civil engineering techniques, knowledge, materials, and design criteria have been adapted to meet evolving requirements.According to BNBC 2020, the seismic zone of Bangladesh has been divided into four parts and in this analysis the building has been designed with the values of the four zones. By using Response Spectrum Analysis, this study aims to investigate how structures behave during seismic activity. Numerous factors, such as story drift, base shear, base reaction, story shear, displacement, and torsional irregularity, are examined for a building with a G+5 layout. The well-known finite element method software, ETABS 2016, is used to perform the thorough analysis and modeling of the structure. This thesis does dynamic analysis on SD type stiff soil under various conditions that match Bangladesh's seismic zones (Zone I, Zone II, Zone III, and Zone IV).
