There are many potential sources of risks which may cause bridge failures and result in numerous economic and human losses during the construction of bridges. Therefore,risk assessment for bridges during construction ...There are many potential sources of risks which may cause bridge failures and result in numerous economic and human losses during the construction of bridges. Therefore,risk assessment for bridges during construction should be taken rigorously to avert bridge failures and casualties. This article presents a fuzzy logic-based method which integrates the fuzzy analytical hierarchy process( FAHP) method based on a 3-point scale,fuzzy logic,and fuzzy set theory into a single synthetic method. In this method,the FAHP method based on a 3-point scale was used to identify and rank diverse risk factors,and fuzzy logic and fuzzy set theory were used to process inaccurate datasets including non-statistical information. After the concept and procedure of the FAHP method based on a 3-point scale were demonstrated,the proposed fuzzy logic-based method was used to perform risk assessment on the Aizhai Suspension Bridge with a main span length of1 176 m in China. The results show that the proposed method can more effectively carry out risk assessment of bridges during construction.展开更多
