基于易损性能分析的山店江大桥高墩抗震评估技术研究
Research on seismic evaluation technology of high piers in Shandian River Bridge based on vulnerability analysis
摘要
Abstract
On the background of NO.1 pier of Shandian River Bridge in Ruchen highway,the damage criteria of the high pier were determined through bending moment-curvature analysis of reinforced concrete section and analytical fragility curves of the pier were obtained through non-linear time-history analysis by use of midas/civil software.The influence of the wall thickness and foundation restraint stiffness on fragility curves of the pier was discussed.The results can provide some references to prediction of structural seismic performance,seismic design,structure reinforcement and maintenance.关键词
