Our project analyzes 432 Park Avenue, one of the world’s most iconic ultra-slender supertall towers, defined by its 1:15 slenderness ratio, square geometry, exposed white in-situ concrete façade, and advanced wind-resistance systems. We studied its structural logic through both hand calculations and computational analysis, including wind load, overturning moment, bending behavior, stress distribution, and displacement performance. Our research combined structural evaluation, construction methodology, and critical design analysis, examining foundations, phasing, aerodynamic systems, and construction technologies. We concluded that the tower’s minimalist form achieves exceptional structural efficiency but also reveals serviceability challenges. Our innovation section proposes future technical improvements such as AMD systems, self-healing concrete, and pneumatic waste collection. Additionally, we fabricated a scaled physical model using 30-hour concrete, replicating real construction by first casting the central core, then building the double-height perimeter façade to simulate the tower’s original in-situ construction process.
