PRETENSIONED PSC GIRDER WITH IMPROVED END STRUCTURE PERFORMANCE

摘要

The present invention enables a width of a lower portion of a cross-sectional neutral axis in a predetermined section of an end part of a start point and an end point of a pretensioned PSC girder. Moreover, a steel material is buried in the lower portion of the cross-sectional neutral axis in the predetermined section of the end part of the start point and the end point of the pretensioned PSC girder. Therefore, an eccentric distance of steel wires of the end part of the girder is reduced and tensile stress of an upper end of the end part is reduced to improve structure performance in order to economically and effectively remove a crack of an upper end of the end part which is the biggest problem of the existing pretensioned PSC girder.;COPYRIGHT KIPO 2016
