Comparative Zone Analysis Of A Moment Resisting High-Rise Structure According To BNBC 2020

Abstract

The Bangladesh National Building Code (BNBC) specifies and regulates the general specifications for structure, 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 Nine-storied (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 of high-rise infrastructure for Zone I, II, III & IV. The decision-making parameters for structural analysis 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 base shear is 0.162 for Zone IV, Maximum lateral deflection is 2.37 inch which is exceed, this model is torsional irregularity for zone IV and maximum story drift data is 3.26 Inch for Zone IV for EQX, EQY, WX and WY respectively. The comparison of the aforesaid analysis parameters is depicted graphically, and relevant tables are presented in this research article. In comparison of wind load and seismic effect on Different zone high rise structures, the requirements of BNBC 2020 usually result in a higher safety and less cost-effective design margin.
