Abstract Carpentry skills were among the most important elements of building practice in premodern China and Japan, and traditional carpentry skills continue in use in both countries to the present day. Although their importance has been greatly marginalised in building practice, in both countries some master carpenters have gained public recognition. This paper compares the modernisation of traditional building knowledge in China and Japan, and the fate of carpentry knowledge as the building industry and the formal discipline of architecture evolved. It distinguishes three phases in this historical trajectory: the period during the introduction of Western architecture as a discipline, when traditional knowledge was rejected or used selectively in the construction of national histories of building; the period when modern technology took over the main building industry and traditional craftsmen had to confront the realities of new technologies of production; and the period, still unfolding today, where heritage movements are promoting the recuperation and development of traditional craft knowledge. For each country, the paper traces how the nation’s history of building was selectively fashioned into an orthodox narrative; explores the content of key early technical works (for China, the official handbook Yingzao fashi [Building standards] and the craftsman’s manual Lu Ban jing [Carpenters’ Canon], and for Japan kikujutsu [literally, “compass and ruler techniques”] books); and shows how a talented master carpenter succeeded in creating a niche for himself within the contemporary heritage culture. It concludes that differences in the cultural respect accorded to carpentry knowledge in the two countries are rooted in the contrasting status of craftsmen in the premodern era.

Obtaining a representative loading spectrum that corresponds well to the reality is still one of the greatest challenges for fatigue life calculations and optimal design of the trailer body. A good qualitative and quantitative knowledge of the spectrum leads to more efficient usage of material, a better design of connection points and an overall decrease of the weight of the trailer, which finally results in a significant decrease in the price of a ton of cargo per km. Despite that, the approach is nowadays mostly based on the experience and rules of thumb. It typically results in over-dimensioning of some parts while other parts remain vulnerable to failure due to unknown loading patterns. This paper describes a generic approach to solve the problems mentioned above applied in a research project named FORWARD (Fuel Optimized trailer Referring to Well Assessed Realistic Design loads). The project lasted two years and was carried out in cooperation with several different trailer manufacturers and 1st tier suppliers. The loading history of more than 1000 hours for five trailer types were captured in the shape of strains, accelerations and velocities of various elements of the trailers, enabling reconstruction of the loading in terms of forces and moments acting on the wheels and kingpin. Parallel to this extensive test-campaign, a novel generic physics-based computational approach was developed to predict selected loads encountered during common manoeuvres to all trailer types. The computational approach was validated against test-data and resulted in creating a generic multibody library applicable for all trailer types, and an automated post-processing routine for the large amount of test-data

The time history of stress beneath a realistic artificial lake with a realistic loading history on a permeable lithosphere can be calculated by solving the consolidation equations for a uniform permeable medium. The evolution of stress conditions towards or away from a Mohr–Coulomb failure envelope illustrates that highest risk of induced seismicity exists at initial loading and in some cases after a down-draw of the lake. The calculated histories depend crucially on hydrologic and geologic conditions which are very poorly known at many artificial lakes. If the formation strengths are constant in the area of the lake, consolidation theory indicates that failure is most likely under the lake in strike-slip or normal fault regimes. If failure occurs due to loading on a thrust fault regime it will occur at an offset from the lake.
