Abstract

Steel-concrete composite twin I-Girder bridges have been built a lot in European countries and some Asian countries, but the lack of redundancy has always been a concern for many other countries. In addition, few experimental studies have been performed on such bridges. On this background, a steel-concrete composite twin I-girder bridge model was designed, and the static loading test was performed. Load versus deflection relationship, and strain development on shear connectors were measured and reported in this paper. Significant shear strain was observed for the stud located near the damaged section. In addition, the failure mode of the twin I-girder specimen in case of one member factures was also discussed. The results obtained in this study can provide information for the design and possible maintenance and rehabilitation of such bridges.
