“…The adoption of timber and steel hybrid structures can, to some extent, be attributed to the flexibility and efficiency of steel, especially in addressing seismic risks [100], particularly in areas with thriving timber industries, such as the Pacific Northwest in the United States and British Columbia in Canada [101]. Hybrid timber and steel structures capitalize on the advantages of both timber, characterized by its low density and ease of construction, and steel, renowned for its high ductility and energy dissipation capabilities [102]. Timber, typically exhibiting brittle failure characteristics [103], has limitations in absorbing seismic energy, whereas steel possesses a high ductility capacity.…”

High-rise residential timber buildings (≥8 stories) are an emerging and promising domain, primarily owing to their capacity to deliver notable environmental and economic benefits over the entire span of their existence. However, it is worth noting that the current body of scholarly work falls short in providing a thorough examination of the key aspects related to architectural and structural design for these environmentally sustainable towers. In an effort to bridge this knowledge gap and deepen our comprehension of the evolving worldwide trends, this research delved into data collected from 55 case studies conducted across the globe. The primary findings unveiled the following: (1) Europe, particularly Nordic countries, stood out as the region boasting the highest number of high-rise residential timber buildings, with North America and the United Kingdom following suit; (2) central cores were the prevailing choice for the core configuration, with the peripheral type following as the second most common option; (3) prismatic forms were the most commonly favored design choices; (4) widespread prevalence of employing pure timber was observed, followed by timber and concrete composite combinations; and (5) structural systems were predominantly characterized by the utilization of shear walled frame and shear wall systems. This research aims to reveal the current attributes of high-rise residential timber buildings, with the expectation that it will offer architects valuable knowledge to assist and steer them in planning and implementing forthcoming sustainable projects within this domain.

“…The use of timber and steel hybrid structures can, in part, be attributed to the adaptability and effectiveness of steel in the face of seismic challenges [87], particularly in regions with robust timber industries like the Pacific Northwest in the United States and British Columbia in Canada [88]. Timber and steel hybrid structures leverage the benefits of both timber, including its low density and ease of construction, and steel, known for its high ductility and capacity to dissipate energy [89]. Timber typically exhibits brittle failure characteristics [90], limiting its ability to absorb seismic energy, while steel possesses a high ductility capacity.…”

Tall timber buildings represent an emerging and highly promising sector due to their potential to yield significant environmental and economic advantages throughout their entire life cycles. Nonetheless, the existing body of literature lacks a comprehensive exploration of the primary architectural and structural design considerations for such sustainable towers. To address this gap and to enhance our understanding of emerging global trends, this study scrutinized data from 49 tall timber building case studies from around the world. The key findings revealed the following: (1) Europe stood out as the region boasting the highest number of tall timber buildings, with North America and Australia following behind; (2) residential applications were the most preferred function for tall timber buildings; (3) central cores were the predominant choice for core configuration; (4) prismatic forms were the most prevalent design preferences; (5) composite materials were notably widespread, with timber and concrete combinations being the most prominent; (6) structural systems primarily featured shear–frame systems, especially shear-walled frames. By unveiling these contemporary characteristics of tall timber buildings, this research is expected to provide valuable insights to architects, aiding and guiding them in the design and execution of future sustainable projects in this field.

“…In recent years, researchers have focused on improving the behaviour of these connections to enhance the seismic resilience of timber structures. One solution to this issue is to use a pure hinge connection for timber structures that can accommodate drift during seismic events, and steel frames can provide ductility to dissipate seismic energy [1]. Alternatively, the connection itself could dissipate the energy by introducing a steel component with reasonable ductile behaviour.…”

The mechanical behaviour of steel is crucial in hybrid steel-timber systems, especially in areas prone to seismic activity. This paper presents a study of a novel semi-rigid connection that employs U-shaped steel plates as seismic fuses in a beam-to-column connection. The connection aims to introduce self-centring steel braced frames as lateral systems, combined with mass timber structures as a gravity load-resisting system, to enhance their structural performance against earthquakes. The fuses are designed to yield in axial compression or tension, with a bending combination that enables the connection to produce yielding at a specific moment level. The study focuses on the results obtained from cyclic fuse testing, connection testing, and comparing the connections to existing solutions to demonstrate their potential as a reliable and resilient option for mass timber buildings in seismic areas. The findings indicate that the developed connections provide reliable ductile behaviour, and timber elements can be protected from damage through the capacity protection provided by the fuses and their yielding mechanism.
