Abstrakt:

Conventional concrete marine structures are difficult to construct on site and can cause pollution of the environment. Therefore, concrete marine structures require the development of methods that can minimize the amount of construction that needs to be performed in the field. This study aims at facilitating assembly through the use of precast girders and precast bent cap and at improving construction efficiency by minimizing cast-in-place structures. The proposed bridge can reduce the negative moment of the girder through continuous connection. In this study, a full-scale connection specimen with a 10.0 m span was fabricated, and the behavior of the precast connection was evaluated by performing a negative moment performance test. In addition, a finite element model was developed to compare each loading step with the test results. The failure mode of the specimen was that the reinforcing bars yielded at the joint of the cast-in-place section and the precast girder. As a result of the study, this proposed bridge is easy to construct because it minimizes the process of connecting the coping and girders using the internal connector. Also, the proposed bridge has 155% higher structural performance than the designed load at the negative moment connection part.
