Steel composite girder bridges provide economic advantages and higher load-carrying capacity than non-composite alternatives. Over the years, a conventional sequence of un-shored construction for steel girder composite bridges has been developed. There is an alternative construction sequence, known as shored construction, that uses temporary supports (discretely or fully supported) for the superstructure during the installation of metal forms and the pouring of concrete. Shored construction also can be used in an Accelerated Bridge Construction (ABC) practice where construction occurs at a nearby site and fully-formed elements are transported to the final site using self-propelled modular transporters (SPMTs). In order to evaluate the effect of shored construction on steel composite girder bridges, a comprehensive review was performed on prior research or guidelines for shored construction of composite steel girder bridges and international codes. A survey questionnaire was also developed and distributed to a list of U.S. and international agencies. Based on the survey results, a summary report on steel composite girder bridges constructed with shored methods in U.S. and other countries was developed and the construction and performance of identified bridges were reviewed. Finally, an analytical study procedure was performed to evaluate the effects of using shored methods for steel composite girder construction and a sensitivity study of varying parameters using the developed analytical study procedure was performed.
