<p>The present invention relates to a prestressed concrete segment girder with reinforced sectional rigidity, enabling the economical shallow depth and long span, wherein the segment girder section of a negative moment section is provided in the shape of a box and the segment girder section of a positive moment section is provided in the shape of an″I″or a″T″such that the sectional rigidity of the girder can be increased, and PS strand fixing parts are provided to the end portions of the shift position parts of positive moment segment girders, the web portions around the shift position parts thereof, and the web portions of the positive moment segments at positions where the negative moment sections and the positive moment sections come in contact with each other such that the first and second tension anchoring parts, management anchoring parts, the third tension anchoring parts or the like can be variously provided. In addition, the performance of the connection joining parts can be increased using the additional anchoring parts and the tension of the segment girders can be freely constructed per step according to the construction procedure.</p> |
