PRESTRESSED CONCRETE GIRDER WITH LARGE VERTICAL ECCENTRICITY, AND CONTINUOUS STRUCTURE OF SUCH PRESTRESSED CONCRETE GIRDERS
The present invention relates to a prestressed concrete (PSC) girder with large eccentricity, and a multi-span continuous structure thereof. As the PSC girder includes an upper flange with a longitudinal cross section wherein a cavity is formed, a center of the cross section of the PSC girder is positioned in a place higher than an existing PSC girder if a height of the girder is identical to a height of the existing PSC girder; thereby the PSC girder obtaining improved bending rigidity by increasing an eccentric distance to a tendon arranged on a tension side from the center of the cross section. As such, the low-height and long-span girder is able to be formed. The purpose of the present invention is to reduce a construction time when constructing a bridge using the PSC girder, and to reduce construction costs.
본 발명은 상부플랜지에 중공이 형성되어 있는 종방향 단면을 가지고 있어서, 동일한 연직 높이를 가지고 있을 경우 단면 중심이 종래의 PSC 거더보다 더 높은 곳에 위치하게 되어 단면 중심으로부터 인장측에 배치된 긴장재 위치까지의 편심거리가 더 증가됨으로써, 휨강성이 더욱 향상되고 그에 따라 저형고 장경간의 거더를 형성하게 되는 "대편심(大偏心)의 PSC 거더와, 그 다경간 연속구조"에 관한 것이다.
