Abstract


A great number of bridge deteriorations are not only harmful to transportation, but also may endanger the people lives and properties. Research on damage evaluation and strengthening methods of bridges are significant. Some serious accidents have happened in many countries since steel bridges were built widely. Therefore, it is necessary to research thoroughly crack damage and strengthening methods of steel bridges. The simulation analysis is an efficient method to deal with bridge cracks. This method provides a useful means of predicting the positions of cracking, analyzing the causes of cracking, and evaluating strengthening methods. Based upon finite element simulation analysis, load tests and long-term observation, a detection and evaluation system for old steel bridge safety was developed in this thesis. The system includes a complete process of cracks repair: to predict and inspect the position of cracking, to analyze the causes of cracking, to provide recommendations for the repair and retrofit of cracking, to evaluate the repair result, so it can guide operating management of steel bridges and ensure the safety of steel bridges. Now it has been successfully applied to Chuanxindian Bridge and Shiziping Bridge of Guangyue railway line, Minjiang Bridge of Neikun railway line, and Baishui River Bridge of Baocheng railway line, and there are good society and economic benefit. The system can diagnose quickly various steel cracks and provide strengthening recommendations. It is very valuable for repairing steel bridges deteriorations of Chengdu Railway Bureau and others, and can guide the theory research and structure details design of steel bridges in our country.
