| dc.description.abstract | The Bangladesh National Building Code (BNBC) specifies and regulates the general
specifications for structural, architecture and design parameters in Bangladesh. In the last three
decades, Civil Engineering techniques, knowledge, and materials as well as design parameters
have been modified as per requirement. Therefore, BNBC 2020 was written to reflect the
transition. In this study, a systematic and parametric structural analysis of a G+5 -story (Low rise)
and G+12-Story (High rise) residential building was analyzed (ETABS 16.0 software) by using
BNBC 2020.In this project lateral load (Earthquake and Wind) affects structural analysis and
design of high-rise infrastructure for Dhaka city. The decision-making parameters for structural
analysis and design are tremor and wind forces, story drift, wind and seismic shear and base shear
for seismic forces according to BNBC 2020. In this study, the maximum story displacement of
low rise to high rise multistory structure is 121.84%, 287.05%, 219.72% and 450% for load EQX,
EQY, WX and WY respectively. And the maximum story drift of low rise to high rise multistory
structure is 60.44%, 66.58%, 113.08%, and 100.488% for load EQX, EQY, WX and WY
respectively. The comparison of the aforesaid design parameters is depicted graphically, and
relevant tables are presented in this research article. In comparison of wind load and seismic effect
on low rise and high-rise multistory structures, the requirements of BNBC 2020 usually result in
a less cost-effective design with a higher safety margin. | en_US |
