A Petal-Structured Vertical High-Rise Integrating Exoskeletal Load Distribution and Passive Environmental Regulation

The increasing vertical densification of cities demands high-rise systems that integrate structural efficiency, environmental performance, and reduced material and energy use. This study proposes a petal-structured high-rise architecture, where curved exoskeletal elements act as primary structural and environmental regulators around a central core. Structurally, the shell–diagrid hybrid configuration converts load into compression-dominant paths, reducing bending moments (25–40%), lateral drift (20–30%), and material demand (15–25%). Aerodynamically, the geometry disrupts vortex formation, lowering wind pressures (18–28%) and improving dynamic stability. Environmentally, vertical ventilation channels enable…
