| dc.description.abstract | This study aims at the comparison of provisions of seismic and wind load analysis
given in BNBC 2020. The revised BNBC 2020 has divided the seismic zones of
Bangladesh into four different categories such as Zone-Ⅰ, Zone-Ⅱ, Zone-Ⅲ and Zone-
Ⅳ respectively. They have different seismic zone coefficients. Finally, structural
analysis and design of a typical G+9 storey residential building situated in two
selected seismic zones is conducted to investigate the seismic behavior of that
building under revised seismic zones and seismic zone coefficients. In this study, the
maximum story displacement of Zone 3 (Chittagong) to Zone 4 (Sylhet) high rise
multistory structure is 0%, 127.57%, 58.34% and 58.14% for load EQX, EQY, WLX
and WLY respectively. And the maximum story drift of Zone 3 (Chittagong) to Zone
4 (Sylhet) high rise multistory structure is 0%, 147%, 57.81%, and 56.45% for load
EQX, EQY, WLX and WLY respectively. The deflection of various members, inter
storey drift, lateral displacement of the whole structure and stress of all members,
inter storey lateral displacement of the whole structure and stress of all members were
checked comparison with limiting value of the design criteria. After the preliminary
design, the various cross section of beams and column and beam which the volume of
concrete and quantity of steel is saved to precise amount and maximize the usable
floor area by satisfying the design criteria. | en_US |
