Abstract: The Chinese Eastern Railway Culture Town is famous for the construction and development of the Chinese Eastern Railway, but its recession is caused by the historical factors and the transport transformation. As a consequence, for such culture towns, there is a mix of problematic issues such as construction and development chaos, spatial structure uncertainty and destroyed townscape. This paper selects the spatial nodes as the research objects to explore its significance within the scope of conservation planning of historical culture town. Taking the practice of Hengdaohezi Town Conservation Planning into account, the author analyzes the status quo of this town presenting the principles of spatial nodes design and establishing the construction guiding framework of spatial nodes.

Abstract: This paper describes the state of the art in design codes and guidance using fracture mechanics. In Germany, a railroad accident occurred in June, 1998, which resulted in about 100 passenger deaths due to a wheel fracture. In September, 1999, a water leak accident due to a crack in a pipe happened at the Tsuruga nuclear plant in Japan. Such serious accidents are the result of fracture events. Fracture mechanics is thought to be a tool to avoid such catastrophic fracture accidents. The state of the art in designing mechanical components or structures applying fracture mechanics was reviewed. The American Society of Mechanical Engineer, the Japanese Society of Mechanical Engineers, the Japanese Welding Society, and the Japanese Industrial Standard were mainly surveyed. This report suggests that a more consideration of fracture mechanics in the design codes and guidance is needed for avoiding fracture accidents in components or structures.
