Safety Performance Evaluation Method of Bridge Structure Based on Reliability Theory
In the whole process of design,construction,operation and maintenance of large bridges,it is difficult to ensure the efficiency and accuracy of structural safety performance evaluation due to the large number of components and parameters involved.In this paper,the safety performance evaluation method of bridge structure based on reliability theory is proposed.Firstly,the main factors affecting the structural performance are analyzed,and the intelligent safety evaluation method of bridge structure is proposed.Secondly,it is found that the intelligent evaluation method proposed in this paper saves 70%of the calculation time compared with the traditional finite element method,and the accuracy is more than 95%.This method transforms the physical problems in the safety assessment process into mathematical problems,which provides a new idea for the safety assessment of bridges.
