Performance-Based Damage Analysis for PC Continuous Rigid Frame Bridges

  • Received Date: 24 Oct 2008
  • Publish Date: 20 Jan 2010
  • In order to find out the causes of the cracking and deflection of PC(prestressed concrete) continuous rigid frame bridges,a damage analysis method based on structure performance was proposed.In this method,the objective manifestations of structure performances are considered as the focus of attention,and the analysis of damage factors for structure performances is as the primary means.By comparing a large number of theoretical and test data and using load test data as a judgment basis to identify damage elements and damage degree,a more realistic performance level of a damaged bridge is obtained,and this performance level can be used as the basis of reliability evaluation and strengthening design.The damage analysis of a PC rigid frame bridge with a span of 160 m,as an example,shows that with the proposed method,the check coefficient of deflection can reach to 0.9.
