“…Xie et al [18] studied the static behaviour of a two-tiered 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 shakingtable 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.

“…Engineers can also undertake experiments under controlled conditions to obtain direct evidence of how hazards interact with infrastructure and result in impact. Rolls-Royce undertook testing of its aircraft engine performance in the presence of volcanic ash to produce volcanic ash flight envelopes (Davison & Rutke 2014), for example, while several other studies have used shaking table tests to obtain primary data on the performance of different building types under different seismic scenarios (Fiorino et al 2019;Xie et al 2019). Obtaining primary data in this way ensures that the collected information is directly relevant to the researcher (and ultimately the user's) needs and answers the key relationship questions that the researcher would like to model.…”

The bridge from a hazard to its impact is at the heart of current efforts to improve the effectiveness of warnings by incorporating impact information into the warning process. At the same time, it presents some of the most difficult and demanding challenges in contrasting methodology and language. Here we explore the needs of the impact scientist first, remembering that the relevant impacts are those needed to be communicated to the decision maker. We identify the challenge of obtaining historical information on relevant impacts, especially where data are confidential, and then of matching suitable hazard data to them. We then consider the constraints on the hazard forecaster, who may have access to large volumes of model predictions, but cannot easily relate these to the times and locations of those being impacted, and has limited knowledge of model accuracy in hazardous situations. Bridging these two requires an open and pragmatic approach from both sides. Relationships need to be built up over time and through joint working, so that the different ways of thinking can be absorbed. This chapter includes examples of partnership working in the Australian tsunami warning system, on health impact tools for dispersion of toxic materials in the UK and on the health impacts of heatwaves in Australia. We conclude with a summary of the characteristics that contribute to effective impact models as components of warning systems, together with some pitfalls to avoid.

“…Because many East Asian timber structures remain standing today despite thousands of years and plenty of seismic events, it has been speculated that joinery connections have played a role in the resilience of historic timber structures. Studies on the behavior of structures with joinery connections in seismic conditions have been carried out using quasi-static testing [14][15][16][17][18][19] as well as experimental dynamic testing [18][19][20][21][22][23][24][25][26]. A general overview of the literature suggests that the seismic resilience of structures with joinery connections can be broadly attributed to a combination of factors: 1) the redundancy offered by the structural configuration of stacking of multiple timber elements, 2) the energy dissipation enabled by the plastic crushing of wood fibers that gives ductility to the global structure, and 3) the ability to replace damaged elements.…”

The mass timber industry offers a compelling pathway for low-carbon structural systems in buildings, replacing carbonintensive materials like concrete and steel with sustainably forested wood. However, conventional structural connections in mass timber construction are largely made of metallic materials, such as screws, nails, and plates. In contrast, joinery, or geometrically interlocking all-timber connections, is globally prevalent in historic timber construction. This paper investigates the potential of applying joinery, specifically the "Nuki" mortise-and-tenon joinery connection, to contemporary mass timber construction from perspectives of structural behavior and carbon savings. Considering single spans supporting one-way cross-laminated timber (CLT) floor systems at the mid-rise residential scale, carbon savings ranging from 7 to 40% are possible at the beam-joint scale by using Nuki joints instead of steel concealed beam hangers, a more conventional mass timber connection. While these savings are smaller at the building scale, the paper nevertheless demonstrates a methodology and results for quantitatively comparing the scale of savings achieved by implementing this historic but contemporarily alternative connection type.
