“…To date, the embedment model has been widely used in the Japanese practical timber design standards (AIJ, 2006) and has also laid the foundation for many subsequent mechanical studies of Japanese timber connections. Kitamori et al (2010) proposed the entire triangular embedment model of the bearing block (Daito) to predict the yielding rotational (Chen, 2007) and (b) naming of the structural members (Yeo et al, 2015). .…”

A static test was conducted to investigate the elastic and post-yielding structural behaviour of complex brackets system along the corridor frame region of the Taiwanese Dieh-Dou timber structures. One partial fully scaled specimen was loaded horizontally under different vertical loading levels. A mechanical model, focusing mainly on the rotational behaviours of bearing blocks and timber interlocking joints, was developed to estimate the global behaviour of complex brackets of the Dieh-Dou corridor frame region. By assuming each spring stiffness to behave bi-linearly, the model is only valid for the estimation of the primary and secondary stiffnesses. The force-deformation relationship is highly dependent on the rotational spring stiffness and vertical loads. Hence, when a heavier vertical load is imposed onto the structure, yielding rotation increases and subsequently, the yielding moment of the bearing block members is improved further. Generally, the predicted model was in good agreement with the observed results, up to the postyielding loading level.

In traditional Chinese timber structures, few tie beams were used between columns, and the column base was placed directly on a stone base. In order to study the hysteretic behavior of such structures, a full-scale model was established. e model size was determined according to the requirements of an eighth grade material system specified in the architectural treatise Ying-zao-fa-shi written during the Song Dynasty. In light of the vertical lift and drop of the test model during horizontal reciprocating motions, the horizontal low-cycle reciprocating loading experiments were conducted using a synchronous loading technique. By analyzing the load-displacement hysteresis curves, envelope curves, deformation capacity, energy dissipation, and change in stiffness under different vertical loads, it is found that the timber frame exhibits obvious signs of self-restoring and favorable plastic deformation capacity. As the horizontal displacement increases, the equivalent viscous damping coefficient generally declines first and then increases. At the same time, the stiffness degrades rapidly first and then decreases slowly. Increasing vertical loading will improve the deformation, energy-dissipation capacity, and stiffness of the timber frame.

“…Both static and dynamic experiments and analysis have been conducted by many researchers who have confirmed the non-linear stiffness of Dou-Gong (Fujita et al, 2000;2016a;Yeo et al, 2016b). The rotation of base Dou often experiences major horizontal deformation in the region of initial stiffness.…”

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.
