The existing steel arch bridges in China were analyzed in terms of steel material, span, structure type, main arch rib form and construction method. The comparison with CFST arch bridges and RC arch bridges is also conducted. It is shown that steel arch bridge has gain rapid development in China since 2000, characterized by long main spans. As for the span, most of the steel arch bridges have a span less than 250 m, while when the span exceeds 350 m, steel arch bridges are strongly competitive against CFST or RC arch bridges. Over 80% of the bridges are through and half-through bridge types, and the arch ribs are hingeless structures. The rise-to-span ratios of the arches are mainly between 1：4 and 1： 5. Most of the arches use solid box ribs, and a small portion of arches use truss ribs in which box sections are mostly adopted for the truss members. The cantilever method and scaffolding method are the two main construction methods used, but some other construction methods have also been developed.展开更多

It provides detailed materials of field research about folk life of stone bridge and village in North China. Here village life world not only includes the folk integration of their everyday life, but also covers local villagers cognitive attitude towards village, such as village history, legend, belief, ritual, clan and other everyday life styles. Expounding and reconstructing of village life world, shows the essential meanings and categories of bridge folklore, it also demonstrates the consequence of shifting connection between stone bridge and village life. Firstly, the crucial context of understanding village life world is still promising. Secondly, folklore fieldwork is an significant part to comprehend the connotation of village life world.展开更多
