A Vertically Integrated Exoskeletal High-Rise with Geometry-Driven Structural and Environmental Performance

The growing verticalization of urban environments has intensified the need for high-rise building systems that simultaneously achieve structural efficiency, environmental responsiveness, and long-term sustainability under complex loading and climatic conditions. This study proposes a vertically integrated exoskeletal high-rise architecture in which architectural geometry operates as a unified structural–environmental system rather than a secondary aesthetic layer. The building is characterized by a continuous curved exoskeleton, vertically integrated shell surfaces, and an elevated ground interface that mediates interaction between the structure, surrounding airflow, and urban microclimate. From a structural mechanics perspective, the curved exoskeletal geometry redirects gravity and lateral loads into compression-dominant load paths, significantly reducing global bending moments, shear concentration, and torsional demand when compared to conventional prismatic frame-core systems. The continuity of the shell enhances global stiffness and stability while enabling efficient load redistribution along the height, contributing to improved performance under wind-induced and seismic excitations. Conceptual analytical formulations indicate reductions in material demand and structural inefficiency through curvature-induced force alignment and shell action. Environmental performance is intrinsically embedded within the geometric configuration of the structure. Vertical curvature, surface articulation, and spatial porosity generate pressure differentials that support buoyancy-driven and wind-assisted passive ventilation, reducing reliance on mechanical cooling systems. The curved façade geometry further enables solar modulation and self-shading, lowering peak solar heat gains while maintaining daylight penetration. The elevated base and open ground interface promote air circulation, heat dissipation, and microclimatic coupling with surrounding natural and urban landscapes. By integrating structural load redirection, passive environmental control, and urban interface within a single geometric framework, this research demonstrates that architectural form can act as a primary regulator of both structural behavior and environmental performance. The proposed vertically integrated exoskeletal model offers a scalable, resilient, and material-efficient strategy for future high-rise development, particularly in dense urban and climatically demanding contexts. The framework establishes a robust theoretical foundation for further numerical simulation, performance-based optimization, and real-world implementation of geometry-driven sustainable tall buildings.
