Analysis on the application of optical fiber sensor in bridge monitoring LUO Shan-hong ， WEI Jian-dong ， QIAN Yong-jiu 2005, 24(3): 4-7.  Abstract ( )   PDF (209KB) ( )   The optical fiber sensor has more accuracy of testing, high undisturbed ability and wide application compared with the tradition electrical sensor. It can be used to measure several physical quantities of bridge structure, such as strain ,crack and vibration. It can not only measure the physical quantities by points, but can also obtain the test results by distribution network. This paper discusses the main characteristics and application of the optical fiber sensor. The attention items of prope References | Related Articles | Metrics

Analysis of bearing capacity reliability on masonry arch-bridge WANG Jun, SONG Yi-fan, HE Shuan-hai 2005, 24(3): 8-10.  Abstract ( )   PDF (187KB) ( )   The system reliability analysis method of arch-bridge is presented based on the failure model of arch rib, which is the most important failure model of arch-bridge. The control sections of arch rib in the analysis of bearing capacity reliability are determined according to the "five-spot coincidence method", which is often used in arch-bridge design. The representative failure models of arch rib are searched and the rib section resistances are calculated by incremental method and disadvantage lo References | Related Articles | Metrics

State-of-the-art of research and analysis of structure and bridge under blast loads LIU Shah-hong ， WEI Jian—dong ， Qi Yong-jiu 2005, 24(3): 16-19.  Abstract ( )   PDF (219KB) ( )   The character of blast loads and the pressure-time profile of a typical blast wave are presented. There are foundations of simulating responses of bridges under blast loads. The main failure forms of high-way bridges are local damaged. It should be noticed that limited areas of bridge may act with blast loads when explosive effects are simulated by calculation method. It can not be simply applying uniform loads on decks. The characters and rules of simulating bridges subjected to blast loading a References | Related Articles | Metrics
