Continuous Reinforced Concrete Rigid-Frame Bridges in China

摘要

Continuous reinforced concrete rigid-frame bridges in China have undergone rapid development in recent decades. Great progress has been made in the design and construction of these types of bridges. Therefore, it is useful to summarize some experiences from these recent developments in bridge design and construction. For this purpose, 349 continuous reinforced concrete rigid-frame bridges built in China during the period from 1988 to 2016 were evaluated. Because of the different design loads, certain design parameters of highway bridges and railway bridges were analyzed, including the span-to-height ratio between girder height and span length, the slab thickness, and the concrete strength. The results provide some guidance for the design and research of continuous rigid-frame bridges.
