ETABS-Based Structural Analysis and Architectural Design of a 21-Story Multifunctional Building in Dhaka: Insights from Shanghai-Inspired Designs on Soft Soil

The present research paper is a detailed study of the architectural design and structural analysis of a 21-story multifunctional tall building that is proposed to be constructed in Dhaka, Bangladesh.The architecture of the building is based on the high-rise buildings of Shanghai, which combine modern architectural design and functionality.The building has a mixed-use design where the ground floor to the 4th floor are commercial retail space and the 5th to the 21st floor are residential units, which are studio apartments and larger multibedroom units.This design combines the principles of vertical zoning, in which various functional areas are arranged effectively in the same building, and land use in the fast-growing urban city of Dhaka is maximized.The main aim of the study is to assess the viability of the proposed building design by performing structural analysis with the help of ETABS software, and it should be in accordance with the Bangladesh National Building Code (BNBC 2020).The architectural design focuses on energy efficiency, comfort, and aesthetic value, and includes such elements as the use of natural light, ventilation, and noise reduction measures to improve the well-being of occupants.The paper provides the main results of structural stability, displacement patterns, inter-story drifts, and reinforcement details, which provide a detailed insight into the issues and solutions of the design of tall buildings on soft soil.
