Brief Description of Prestressed Concrete Structures,apacity of prestressed concrete structures. This book clarifies the mechanical behavior of corroded prestressing strands, corrosion-induced cracking, bond degradation, prestress loss, and structural performance deterioration of prestressed concrete structures and proposes the corresponding predictio

Mechanical Behaviors of Corroded Prestressing Strands,orroded strands are obtained through controlling stress level, corrosion time, and chloride ion concentration under artificial climate conditions. Then, the size and geometry of corrosion pits are measured, and its probability distribution is investigated. Furthermore, static tensile tests are carri

Bond Behavior Between Strand and Concrete with Corrosive Cracking,iscusses the bond behavior between corroded strand and concrete. First, the effects of corrosion-induced crack on the bond between strand and concrete are studied based on the pull-out test; the confinement role of stirrups on the deterioration of bond behavior affected by concrete cracking is addre

Creatinine-Test

Prestress Loss and Transfer Length Prediction in Pretensioned Concrete Structures with Corrosive Crodel, considering the coupled effects of concrete cracking and bond degradation, is proposed to predict the corrosion-induced prestress loss in prestressed concrete structures at first. Then, an analytical model, considering the coupled effects of the Hoyer effect and corrosion-induced cracking, is

Secondary Anchorage and Prestress Loss of Fractured Strand in PT Beams,ctural safety. An experimental test with five specimens is designed to investigate the secondary anchorage and residual prestressing force in locally corroded post-tensioned concrete beams after strand fracture. Then, an analytical method is proposed to determine the damage control section of locall
