Abstract

This study is to give more accurate information by performing the time depend ent analysis to take into account the long-term losses of precast PSC concrete bridge and analyzing the second stress, final camber and cross section stress of precast PSC caused by creep and drying shrinkage. As time goes by, the stress and deformation in the cross section vary continuously by the influence of creep and drying shrinkage. Due to this, the stress redistribution occurs and the internal force variation also happens along the point on the same cross section and with the passage of time.
