“…Xie et al [18] studied the static behaviour of a twotiered Dou-Gong system reinforced with super-elastic alloy, and found that the pre-strain of the super-elastic alloy can significantly increase the damping ratio in the structure. Previous studies [19][20][21][22] tried to evaluate the mechanical properties and safety state of an entire timber structure through finite element modelling, mathematical methods, and a shaking-table test. However, all of these studies focused on the timer components and timber frames without considering the infill walls.…”

Kanchuang frames are important parts of traditional timber architecture in China. This paper used experimental and numerical methods to study the restoring force model of Kanchuang frames, which were used frequently in Chinese ancient timber structures, particularly in North China. The prototyped test model is a type of Chinese traditional timber architecture named Qilinyingshan. It was widely used in ancient timber buildings preserved from the Ming and Qing dynasties. This study analyzed the loading process and failure modes of the test model, and the skeleton curve and hysteretic curve data were collected. Moreover, a dimensionless skeleton curve model was developed based upon the findings. The hysteresis loops of the test model were also analyzed, and it was found that each hysteresis loop can be divided into several feature segments according to their stiffness at different loading stages. Regression analysis was also used to obtain the stiffness degradation curvilinear equations of the feature segments. Finally, a hysteresis force model of a Kanchuang frame was established. This study also found that the loading process can be divided into three stages: the elastic stage, in which all of the components are in good condition; the elastic–plastic stage, in which cracks gradually develop on the wall; and the new elastic–plastic stage, after which the wall collapses. It was found there was consistency between the restoring force model and the test results, indicating that the model is valid and reliable. The skeleton curve model and hysteretic model provide reference for the nonlinear seismic response of ancient timber architecture.

“…A simplified hybrid method has been presented for nonlinear FEM, particularly for timber frame buildings, such that the elements are modelled using the experimental testing results from the substructures [100]. Hybrid simulation has been utilized to investigate the seismic vulnerability of timber frame buildings [101][102][103][104][105][106][107][108][109], and then developed for numerical simulation of log houses [110][111][112][113][114][115] and post and beam structures [116][117][118][119][120][121].…”

The conservation of heritage structures is pivotal not only due to their cultural or historical importance for nations, but also for understanding their construction techniques as a lesson that can be applied to contemporary structures. Timber is considered to be the oldest organic construction material and is more vulnerable to environmental threats than nonorganic materials such as masonry bricks. In order to assess the structural vulnerability of heritage timber structures subjected to different types of risk, knowledge about their structural systems and configurations, the nature and properties of the materials, and the behavior of the structure when subjected to different risks, is essential for analysts. In order to facilitate the procedure, different assessment methods have been divided into the categories in situ and ex situ, which are applicable for vulnerability assessments at the element and full-scale level of a case study. An existing methodology for structural vulnerability assessments and conservation of heritage timber buildings is reviewed and a new methodology is proposed.

To improve accuracy of safety state evaluation results for ancient timber buildings and to know the real state of the building, a safety grade evaluation model of ancient timber buildings is established based on attribute mathematic theory. From the perspective of macro, micro, qualitative, and quantitative, 22 factors may adversely affect the safety state of ancient timber building are considered in this model. First, evaluation system is established, and evaluation indexes are selected based on former study, seismic damage data, and Chinese current code about ancient timber buildings. In the evaluation system, whole building is divided into four parts, which are wood frame, enclosing wall, foundation, and plinth. Different parts contain different components. Every component has its own evaluation indexes. Second, based on the AHP and entropy method, the comprehensive empowering method is used to determine the weights of the indexes. Third, the attribute recognition model is established to identify the safety grade of components or units. Fourth, based on the evaluation results of components, safety grade of units is identified. Then, safety degree of the entire building is determined by the minimum safety grade of units. At last, the model is applied to the “Liben hall” in village Siping, Zhejiang province, China, and the assessment results are consistent with the results of damage identification.
