“…These timber buildings have diverse connection systems, such as dovetail connections (Chang & Hsu, 2005) and Dou-Gong system. The anti-seismic performance of historic timber buildings has been extensively studied over the past 20 years (Fang et al, 2001a;Fang et al, 2001b;Fujita, Hanazato & Sakamoto, 2004;Chang, 2005;Suzuki & Maeno, 2006;Chang, Hsu & Komatsu, 2006;Chang & Hsu, 2007;Yu et al, 2008;Chang et al, 2009;Xue et al, 2015;Yeo et al, 2018;Xie, Araki & Chang, 2018), and it has been recognised that Dou-Gong systems in historic timber buildings play an important role in resisting seismic action. Dou-Gong systems are located at the top of columns to support upper structures and transmit the weight of both the structures and the roof to the columns and the foundations.…”

The Dou-Gong system in Asian timber structures plays an important role in resisting seismic action. Traditional carpentry in Asia uses timber pegs to connect components, which enables relative movement between components and hence provides friction to dissipate energy in an earthquake. This method, however, has some shortcomings, such as inadequate stiffness to resist a large lateral force, and, therefore, the structures tend to exhibit permanent deformation after earthquakes. This study proposes a new technique by using super-elastic alloy bars to replace conventional wooden peg connections to enhance the seismic performance of the structures. Static pushover experiments were conducted on full-scale two-tiered Dou-Gong systems, and high-strength steel and conventional wooden pegs were used as benchmarks. The ultimate stiffness of the Dou-Gong system has shown an increase when both high-strength steel and super-elastic alloy bars were used, but only super-elastic alloy can provide a consistently high damping ratio. This technique also involves pre-strain of the super-elastic alloy, and the outcomes of this series of experiments have shown that pre-strain of the super-elastic alloy can significantly increase the damping ratio in the structure, and, hence, more energy is dissipated. The results of this paper can be used in projects of timber structures using the Dou-Gong system.

“…Most of densely distributed locations of such buildings lie in the seismic belts in East Asia, and hence there is an urgent demand for implementing protection measures against earthquakes. To this end, a significant research effort has been devoted, especially from the late 1990s, to assess the seismic performance of historic timber buildings (Fang, et al, 2001a;Fang, et al, 2001b;Suzuki & Maeno, 2006;Yu, et al, 2008;Xue, et al, 2015).…”

Historic timber structures that are widely distributed in East Asia are suffering from the earthquakes. This research is aiming to develop a technique to enhance the seismic performance of historic timber buildings with Dou-Gon system. High strength steel bars and super-elastic alloy bars have been used instead of the conventional wood peg connection to connect the base Dou and the column. Pushover tests have been done under all loading conditions. The energy dissipation capacity and the ultimate strength of the base Dou-Gon system have been increased by this simple technique. Base Dou-Gon system with super-elastic alloy bar connection shows a better anti-seismic performance due to its constant damping behaviour and longer fatigue life. Moreover, pre-strain of the super-elastic alloy bar can give a better damping behaviour to the base Dou system.

Sakarya City, as the host of many civilizations, has many historic monuments. The city is in the most active earthquake zone in the region. The minarets of mosques are the most important structures because they are slender. Therefore, they are sensitive to lateral loads, and earthquakes and strong winds may cause damage to these structures. The highest number of mosque minarets partly or totally collapsed in the 1999 Kocaeli and Düzce earthquakes that occurred in Turkey. The region is rich in trees, so timber has been used in the construction of different structures in Sakarya City and the vicinity for many years. In this study, five historic timber minarets in Sakarya City were experimentally and computationally examined to determine the effects of the construction techniques and geometrical properties on the dynamic behavior of the minarets. Ambient vibration tests of timber minarets were performed, and the construction techniques and geometrical features were examined; the results of these are discussed below. It was determined that the outer wall construction technique, body height, slenderness, and cross-sectional area play important roles in the dynamic behavior of timber minarets. Finally, an empirical formula was derived from the relationships for rapid estimation of the fundamental period of timber minarets.
