| dc.description.abstract | Bangladesh is located in a seismically active area. The ground shakes during an earthquake. As a result,
the base of a building sitting on it will move. So it is necessary to ensure the adequacy of the structures
against the horizontal load effect. With the help of BNBC's guidelines, the risk of failure in newly built
infrastructure exposed to wind and earthquakes can be minimized. The latest BNBC code is Bangladesh
National Building Code 2020 (BNBC 2020). In BNBC-2020, the seismic zone of Bangladesh has been
divided into categories, such as Zone-I (seismic intensity: low), Zone-II (seismic intensity: moderate),
Zone-III (seismic intensity: severe), and Zone-IV (seismic intensity: very severe). They have different
seismic coefficients. This paper compares different seismic zone analyses of a multi-storeyed (G+9)
residential building in all four seismic zones with and without shear wall. This paper's primary goal is to
examine how this building responds to earthquakes in the updated seismic zone and coefficient and the
effects of the shear wall location. The analyses. For different zones, wind speed and the seismic
coefficient have been changed, and it mainly impacts the buildings. To compare these impacts based on
environmental loads, we used four different locations in four different seismic zones. The locations of the
different zones are Rajshahi (Zone-1), Dhaka (Zone-2), Rangpur (Zone-3), and Sylhet (Zone-4). Structural
analysis is done by using ETABS (Extended Three-Dimensional Analysis of Building Systems) and
compare the storey displacement, drift, stiffness etc. The results shows that the using of shear wall has an
impact on design and stability of the structure.
