| dc.description.abstract | Moment Resisting Frames (MRFs) are extensively used structural systems in urban
construction worldwide due to their superior performance in resisting lateral loads,
including wind and seismic forces, while efficiently supporting vertical loads from
structures. Conversely, reinforced concrete dual systems integrate the energy
dissipating characteristics of MRFs with the high in-plane stiffness of shear walls. This
combination enhances their ability to control lateral loads from wind and earthquakes,
making them particularly suitable for high-rise buildings. This study investigates the
structural performance of a (G+7) storied residential building across different regions
in Bangladesh, using reinforced concrete Special Moment Resisting Frames (SMRFs)
and dual systems comprising intermediate MRFs and special shear walls. The analysis
was conducted using ETABS software, following the BNBC 2020 standards. Key
structural parameters such as story displacement, story drift, story shear, and base shear
were assessed to evaluate the structural performance. Additionally, a cost assessment
was carried out to analyze cost efficiency and material requirements. The analysis
revealed that the dual system can reduce wind-induced story displacement compared to
SMRF. These results highlight the potential structural advantages and of dual systems,
particularly in wind-prone areas, making them a feasible solution for high-rise
residential buildings in such regions. | en_US |
