ABSTRACT

Employing tilted forms in tall buildings is a relatively new architectural phenomenon, as are the cases with the Gate of Europe Towers in Madrid and the Signature Towers in Dubai. This paper studies structural systems for tilted tall buildings. Tilted tall buildings are designed with various structural systems, and their structural performances are studied. The structural design of today’s tall buildings built with higher strength materials is generally governed by lateral stiffness. Tilted towers are deformed laterally not only by wind loads but also by dead and live loads due to their eccentricity. The impact of eccentricity on the gravity and lateral load resisting systems are studied. Comparative efficiency of various structural systems employed for tilted towers are presented.
