ABSTRACT
This research presents a performance-based impact-resistant design method for reinforced concrete bridge members. First, the effectiveness of the equivalent static design method given in the current specifications is discussed. Then the performance standards of reinforced concrete members under impact loading are given. The goals for impact-resistant design include structural safety, functionality and socio-economic factors. And then the failure probability of reinforced concrete members with different damage degrees under impact loading is determined, considering the random probability distribution of the loading effect and the section bearing capacity. Finally, combining the current reliability specifications and the risk-based analysis method, the performance-based analysis and evaluation method based on the target reliability is proposed. The applicability and rationality of this design method are illustrated through a typical case study of a reinforced concrete column.
