New Trends Towards Enhanced Structural Efficiency and Aesthetic Potential in Tall Buildings: The Case of Diagrids

Abstract

Due to the increasing number of people and activities within the cities, tall buildings are exploited worldwide to address the need for new living and commercial spaces, while limiting the amount of used land. In recent decades, the design of tall buildings has undergone a remarkable improvement, thanks to the development of new computational tools and technological solutions. This has led to the realization of innovative structural systems, like diagrids, which allow the achievement of high structural performances and remarkable architectural effects. In this paper, a thorough and updated review of diagrid structural systems is provided. Simplified methodologies for the preliminary design and structural analysis are reported. Special attention is also paid to the optimization of the structural response based on the geometrical pattern. A discussion of the effect of local deformability, stability and shear-lag phenomenon is carried out. Results from nonlinear and dynamic analyses for the seismic assessment of diagrid systems are reported, and attention is also paid to the recent research on diagrid nodes. Eventually, an overview of twisted, tapered, tilted and freeform diagrid towers is carried out, with a final mention of hexagrids, another recent evolution of tubular systems for tall buildings.

Yüksek Yapıların Yapım Tekniklerinin İncelenmesi

“…Yapının dış cephesinde eğrisel kolon ve kirişler kullanılarak üçgen modüller oluşturulmakta daha sonra oluşturulan modüller üst üste konularak yüksek yapılar inşa edilmektedir (Baysal Balcı, 2013). Yapı üzerini etkileyen düşey ve yatay yükleri aynı anda karşılayabilen diyagonal sistemler, ilk olarak 1920 yılında Rus Mimar Vladimir Shukhov tarafından tasarlanmış olan Moskova'da bulunan bir yayın kulesinin inşasında kullanılmıştır (Scaramozzino, Lacidogna ve Carpinteri, 2020). Bu tür sistemler mimari tasarım zenginliğini artırmanın yanı sıra deprem ve rüzgâr yükleri gibi dinamik yükleri de karşılayabildiğinden günümüz yüksek yapıların tasarımında da sıkça kullanılmaktadır (Kutluğ ve Tuğrul, 2013).…”

Performance assessment of Timber High-rise Buildings: Structural and Technological Considerations

“…Adopting nature-inspired mimetic patterns has investigated innovative and unconventional schemes [1,2]. An in-depth and updated review of previous research works on tessellated tubes is reported in Scaramozzino et al [3], where special attention is paid to the sustainable design of tall buildings. Among different geometrical patterns for tubular systems, diagrids have undeniably been the most popular.…”

Structural efficiency of block for aviation piston heavy fuel engine

“…Structural efficiency is an evaluation method to quantify the overall performance benefits of various structural improvement designs on parts. Combining with the corresponding evaluation objects, the corresponding connotation is proposed, which is widely used in the aviation industry and building structure (Ylvinger, 2000;Mena, 2020), but it is not involved in aviation heavy fuel piston engines (Scaramozzino et al, 2020;Hunt et al, 2019). Hong proposed a quantitative structural efficiency evaluation method, which realized the parametric method to evaluate the quality of structural design (Hong et al, 2020) .…”
