Shaking Table Tests of 'Masugumi' Used in Traditional Wooden Architectures

Mechanical model for complex brackets system of the Taiwanese traditional Dieh-Dou timber structures

“…From Kyuke's (2008) works and experiment observations of this study (Yeo et al, 2013a(Yeo et al, , 2013b(Yeo et al, , 2015, the back-end multiple bearing blocks are assumed to be a three-layer spring model. As shown in Figure 16, the threelayer complex shares the uniform shear force in each layer.…”

“…The bottom Dou members tend to sustain more moment than the members above; hence, the rotational angle at the bottom layer is greater than at the upper layers. Based on the definitions proposed by Kyuke et al (2008), and without taking account of the effects of the vertical load, the following equations can be derived…”

“…In addition, both Taiwan and Japan experience similar natural disaster calamities such as earthquakes and typhoons on a yearly basis; hence, in this study, the authors decided to apply the structural analysis knowledge gathered from Japanese research (Architectural Institute of Japan (AIJ), 2006; Fujita et al, 1999Fujita et al, , 2000Fujita et al, , 2001Inayama, 1991Inayama, , 1993Kitamori, 2010;Kitamori et al, 2010;Kyuke et al, 2008;Madsen et al, 1982), as these findings might be relevant to the Taiwanese context.…”

“…Although the structural forms and joint design systems of Japanese and Chinese traditional timber structures are generally different from Taiwanese traditional timber structures, some similarities, such as heavy roof loads, the ‘Dou-stacking’ property of complex brackets and the ‘Penetrating-joint’ ( Nuki ) concept, are commonly observed. In addition, both Taiwan and Japan experience similar natural disaster calamities such as earthquakes and typhoons on a yearly basis; hence, in this study, the authors decided to apply the structural analysis knowledge gathered from Japanese research (Architectural Institute of Japan (AIJ), 2006; Fujita et al, 1999, 2000, 2001; Inayama, 1991, 1993; Kitamori, 2010; Kitamori et al, 2010; Kyuke et al, 2008; Madsen et al, 1982), as these findings might be relevant to the Taiwanese context.…”

Enhancing the seismic performance of historic timber buildings in Asia by applying super-elastic alloy to a Chinese complex bracket system

“…The nonlinear nature of the restoring force of Dou-Gon has been investigated through static and dynamic experiments (Fujita, 2000;Suzuki, 2006;Kyuke, 2008;Tsuwa, 2008;Yu, 2008;Xue, 2015;Yeo, 2016a;Yeo, 2016b) and dynamic simulations (D'Ayala, 2008;Tsai, 2011). It has been pointed out that Dou-Gon dissipates significant amount of energy mainly due to sliding between wood elements and yielding of wood elements in compression perpendicular to the grain (Fujita, 2000;Kyuke, 2008;Xue, 2015;Yeo, 2016a;Yeo, 2016b). Tsuwa et al (2008) and derived formulations for predicting the skeleton curve of the restoring force from the compression tests perpendicular to grain.…”
