Analysis and Design of UHPC Tall Buildings in UAE with Ductile Coupled Shear Walls Lateral Load Resisting System

This research paper presents the findings of an attempt to measure the implications of using ultra-high-performance concrete for shear walls in tall buildings considering structural efficiency and environmental sustainability. 20 and 40-story structures with the lateral force-resisting system consisting of coupled special reinforced concrete shear walls system were analyzed and designed using the normal strength concrete of 60 MPa and ultra-high-performance concrete of different compressive strengths for each designer. The results showed the used layout for the lateral load resisting system has successfully mitigated the torsional effects as well as enhancing stress distribution within the buildings. As a consequent, it was shown that using a well-designed and inspected configuration can reduce the need for ultra-high-performance concrete. Also, in case of very efficient lateral load resisting systems with moderate height, the use of ultra-high-performance concrete can badly affect the building performance and increase the construction cost.
