“…Seismic retrofit strategies have been developed in the past few decades following the introduction of new seismic provisions and the availability of advanced materials. Different techniques and methods are applied for a seismic retrofitting of different structures (e.g., concrete structures [97][98][99], timber structures [35,100,101], historical and heritage structures [102][103][104] and especially masonry structures [3,[105][106][107]).…”

Use of timber as a construction material has entered a period of renaissance since the development of high-performance engineered wood products, enabling larger and taller buildings to be built. In addition, due to substantial contribution of the building sector to global energy use, greenhouse gas emissions and waste production, sustainable solutions are needed, for which timber has shown a great potential as a sustainable, resilient and renewable building alternative, not only for single family homes but also for mid-rise and high-rise buildings. Both recent technological developments in timber engineering and exponentially increased use of engineered wood products and wood composites reflect in deficiency of current timber codes and standards. This paper presents an overview of some of the current challenges and emerging trends in the field of seismic design of timber buildings. Currently existing building codes and the development of new generation of European building codes are presented. Ongoing studies on a variety topics within seismic timber engineering are presented, including tall timber and hybrid buildings, composites with timber and seismic retrofitting with timber. Crucial challenges, key research needs and opportunities are addressed and critically discussed.

“…At present, it is common that the materials used in old structures and constructions, such as heritage buildings, require a retrofitting in order to ensure their safety (Petrovčič and Kilar, 2020;Vereecken and Roels, 2016;Abdel-Aty, 2018). The need for rehabilitation interventions could be due to the degradation of the materials (Brimblecombe and Lefèvre, 2021), caused by the attack of aggressive substances over time which would affect their durability, the exposure to fire or other accidental situation (Pauletta et al, 2018;Pazlar and Kramar, 2015), or even due to changes in the use of the ancient building (Pigliautile et al, 2019).…”

“…In the model, semi-rigid connections have been modelled and analysed to determine the rotational stiffness. Yaser in (Abdel-Aty and Amin 2018) studied the in plane stiffness of timber roofs and proposal for seismic retrofitting enhancing how the in-plane stiffness should be considered and not disregarded. Descamps et al in (Costa et al 2018) studied reinforcement in beams and joints in order to increase to increase the moment of resistance (and so limit the deflection too) or to increase the in-plane stiffness for lateral loads.…”

Vaernes church is one of the oldest mediaeval stone churches with the original wooden roof in Norway. The roof is made of several crossed layers of wooden boards connected with a large number of wooden dowels and has stood for centuries, but there are visible deformations in the lower parts of the structure. In this work, finite element models of the roof are presented in an attempt to characterise the behaviour of the wooden connections in the diaphragm. Two main scenarios are discussed: a first scenario that takes into consideration only the frame with line loads, considering the wooden boards merely as loads and a second scenario where the wooden boards are considered collaborating planks that influence the behaviour of the structure. As result of the work, it is possible to state that the wooden planks provide a stiffening effect, distributing the load on the gable walls. .
