| dc.description.abstract | The earthquake, which has the greatest impact on both human life and built
infrastructure, is the most devastating and unpredictably occurring natural occurrence.
A structure can suffer severe damage as a result of seismic forces brought on by
earthquakes, which frequently result in structural collapse. Since the day it became a
reality, earthquakes have today become a threat to human advancement. According to
previous earthquakes, a significant number of structures have unquestionably suffered
damage as a result of earthquakes. Due to the spread of earthquake-prone regions,
earthquake analysis is now one of the most important factors in the planning of any
structure. Bangladesh is especially vulnerable to earthquake activity. Because of this,
it is now crucial to choose seismic reactions over constructions in various zones. This
study examines the design and analysis of a (G+9) 10 storied residential structure that
is situated in Bangladesh's Zone I, Zone II, Zone III, and Zone IV seismic zones. In
this study, BNBC 2020 and ETABS 2018 are used to analyze the seismic response
and stability of residential buildings against extreme earthquakes or seismic
conditions. This research defined the base shear, torsional irregularity, story drift, and
story displacement of various seismic zones in Bangladesh and presents the
comparative analysis. The highest story drift, story displacement and base shear were
found in Zone IV (Habiganj), then Zone II (Dhaka), then Zone III (Tangail), then
Zone I (Pirojpur). Torsion irregularity was same and normal for all zones. The design
was ok for all seismic zones in Bangladesh. According to research, whenever the
seismic coefficients increase, the seismic effects also increase. Eventually alternative
things are happened due to other coefficients such as Zone II (Dhaka). Finally, we can
state that the research work helps to solidify our understanding of the analysis and
design of structures under seismic influences. | en_US |
