“…Finally, with focus on the seismic performance of timber structures, two state-of-the-art reviews were performed. One with the purpose of discussing displacement-based seismic design and their applications to timber buildings [19] and, on the other hand, only for CLT structures, the discussion was conducted mainly for experimental tests, numerical models, qbehavior factor and seismic design [20]. Given the facts mentioned, even with the research carried out, the regulations still do not provide a reliable method of seismic design, so there is still a need for adjustments between reality and design.…”

A two-story full-scale CLT building of 4.5 m x 9.1 m in plan, with a height of 5.04 m, was tested under quasi-static monotonic and cyclic loading for platform-type construction. The main objectives were to evaluate the global response of the structure, the performance of the shear walls, the behaviour of the connectors (hold-downs and angle brackets) and the frequency response of the structure during the tests. Lateral loads were applied on the storeys inducing torsion to the building. Loading procedure, number and disposition of connectors varied between tests. However, it is important to note that, in order to avoid a possible overlap of effects, the metal connectors hold-downs and angle-brackets only have been placed in CLT shear walls in each loading direction. In terms of performance, longitudinal direction presented a stiffer behaviour when compared to the transverse, where it was possible to verify greater sliding in the longitudinal direction and global rocking in the transverse direction. The results of this experimental campaign will be used for further analytical and numerical analyses, in order to help to implement more detailed seismic analysis, namely pushover, of CLT constructions.

“…Typically, the three important directions related to the anisotropic properties of timber are the tangential, radial, and longitudinal axes. The properties of timber along different directions are described in these valuable references [1,27,28]. The compressive and tensile strengths are higher along the longitudinal direction than their counterparts along the radial direction.…”

Design is a goal-oriented planning activity for creating products, processes, and systems with desired functions through specifications. It is a decision-making exploration: the design outcome may vary greatly depending on the designer’s knowledge and philosophy. Integrated design is one type of design philosophy that takes an interdisciplinary and holistic approach. In civil engineering, structural design is such an activity for creating buildings and infrastructures. Recently, structural design in many countries has emphasized a performance-based philosophy that simultaneously considers a structure’s safety, durability, serviceability, and sustainability. Consequently, integrated design in civil engineering has become more popular, useful, and important. Material-oriented integrated design and construction of structures (MIDCS) combine materials engineering and structural engineering in the design stage: it fully utilizes the strengths of materials by selecting the most suitable structural forms and construction methodologies. This paper will explore real-world examples of MIDCS, including the realization of MIDCS in timber seismic-resistant structures, masonry arch structures, long-span steel bridges, prefabricated/on-site extruded light-weight steel structures, fiber-reinforced cementitious composites structures, and fiber-reinforced polymer bridge decks. Additionally, advanced material design methods such as bioinspired design and structure construction technology of additive manufacturing are briefly reviewed and discussed to demonstrate how MIDCS can combine materials and structures. A unified strength-durability design theory is also introduced, which is a human-centric, interdisciplinary, and holistic approach to the description and development of any civil infrastructure and includes all processes directly involved in the life cycle of the infrastructure. Finally, this paper lays out future research directions for further development in the field.

“…Recent advancement in earthquake engineering has led to the development of seismic resilient construction technologies that employ passive control systems to withstand strong earthquakes with limited structural damages (Ríos-García and Benavent-Climent 2020). A number of successful building projects utilizing mass-timber components is spreading in recent years thanks to their optimal strength-weight ratio, with important economic, social, environmental benefits and reduced construction time (Loss et al 2018;Ugalde et al 2019). Among the various structural low-damage solutions for medium and high-rise multistorey timber buildings located in high seismic risk area, moment-resistant timber frame (Polocoșer et al 2018), platform frame or cross laminated timber (CLT) constructions (Ceccotti et al 2013;Van de Lindt et al 2018;Masaeli et al 2020;Chen et al 2020) are emerging.…”

With the increased number of multi-storey buildings in seismic areas, research efforts have been focused on developing earthquake resilient systems, such as low-damage techniques based on the combination of post-tensioning and dissipating devices. This paper describes the experimental study performed on a 3-storey post-tensioned timber framed (Pres-Lam) building equipped with energy dissipating systems. The testing project consisted of three phases adopting different configurations of the experimental model: (1) post-tensioning to beam-column joints only, (2) post-tensioning and dissipative rocking mechanisms and (3) post-tensioning and dissipative braces. The main objective of this paper is to experimentally investigate on the seismic response of a large-scale specimen with dissipative braces located in high seismic area, considering construction details similar to those adopted in practical applications. During the experimental campaign, the test frame was subjected to more than one hundred ground motions considering a set of seven spectra-compatible earthquakes at increasing intensity levels. The dissipating bracing system with external replaceable hysteretic dampers improves the seismic resilience of multi-storey Pres-Lam buildings, showing inter-storey drift comparable to those with rocking walls, with full recentring capability and without structural damages or post-tensioning losses through seismic tests.
