During modular bridge construction, the construction delay and the problems of workability due to the high-altitude operations are occurred by using in-site concrete diaphragm. To solve these problems, selected alternative suitable for modular bridge diaphragm is needed. Therefore, in this study, to select the suitable diaphragm for modular PSC T-Girder bridge, seven diaphragm specimens were fabricated and static loading tests were carried out. Through the static load tests, the behavior of diaphragm in terms of joints and load distribution was observed and experimental results were analyzed and compared with each data. Finally, the alternative of suitable diaphragm for modular PSC T-Girder bridge was proposed considering the structural performance and workability.
