Abstract
Recently, it was reported that deflection continued to extend far beyond the predicted value at the time of the design in PC bridge. In this study, in order to develop an analytical method to estimate the long-term deflection of PC bridge, an frame model considering time dependent behavior on each part of the section was proposed. In addition, long-term concrete shrinkage model was formulated based on FE analysis for various types of size and shapes. By using this frame model, long-term deflection of existing two PC bridges was calculated. As a result, it was verified that long-term deflection could be approximately evaluated.
