This study was conducted to develop 60 m span PSC girders with shallow depth considering their economic efficiency and constructability. A cross section of bulb-tee type with a half deck was applied to the PSC girders. Especially this paper looks carefully at effective ways to arrange the tendon for long span girders and also explains the decision making process. First, it was preferentially considered that tendons be arranged in a straight line for as long as possible. Second, the division of the tendon layout was considered with two sections using the intermediate anchorage zone. With this tendon layout, a PSC girder with span length of 60 m was developed in this study. The full scale PSC girder was made for a four point bending test by static load. The test results showed the effect of the tendon layout on long span PSC girders and the good structural performance of the girder. |
