Lateral Slide of Multi-Span Bridges: Investigation of Connections and Other Details Phase I

The Iowa DOT continues to advance techniques for accelerating the construction of bridges in Iowa. In approximately 2020, the Iowa DOT plans to construct its first ever multi-span bridge using the lateral slide technique. This next generation of construction builds upon the successful slide of the single span bridge near Massena, IA. With the more complex construction associated with a multi-span slide, several questions have arisen regarding various connection details (particularly those at or near the piers). The work proposed here will synthesize available information on other lateral slide projects, present applicable design information, monitor bridge behavior during an upcoming lateral slide, and work with the project Technical Advisory Committee to define other needed work. The approach proposed here is to collect information on various details and construction approaches for previously completed lateral slide projects. These projects and details will then be evaluated to identify those deemed successful as they relate to the specific Iowa DOT bridge. If deemed necessary, the research team will then determine the need for and propose on additional analytical and/or experimental investigations. Finally, where possible, design guidance could be developed for applicable details deemed to be of greatest interest and value to the Iowa DOT. To achieve the objectives of this project, several tasks are proposed. The tasks will be performed in close communication with a Technical Advisory Committee (TAC) throughout the duration of the project. To this end, the research team plans to hold quarterly meetings with the TAC to update them on progress and to ensure that the research direction is as desired. The Tasks described here are the anticipated first phase of what could be a multi-phase project. After the descriptions of the Phase I tasks below, preliminary thoughts on possible additional phases are briefly mentioned.
