| 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 was
written to reflect the transition. In this study, a systematic and parametric structural
analysis of six-story (Low-rise) and Twelve-story (High-Rise) residential building was
analyzed (ETABS 21. 0. 0 software) by using BNBC 2020. In this project lateral load
(Earthquake and Wind) affects structural analysis and design of high-rise infrastructure
for Kushtia which is situated in Kushtia district, Khulna, Bangladesh. 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 multi story structure is 197. 08%, 247. 95%, 453. 82% and 548. 35% for load EQX, EQY,
WX and WY respectively. And the maximum story drift of low-rise to High-Rise multi story structure is 53. 35%, 92. 98%, 181. 24%, and 268. 10% 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 multi-story structures, the
requirements of BNBC 2020 usually result in a less cost-effective design with a higher
safety margin. | en_US |
