| 摘要： | This report presents new simplified connections between full-depth precast concrete deck panels and beams. These new connections are simplified with regard to constructability, inspection during construction, reducing the impact of construction on traffic, and future deck replacement and are based on comprehensive analytical and testing programs. The new system utilizes clustered shear connectors spaced up to 6 ft and connected to the deck system using ultra-high performance concrete (UHPC). In addition, the new system utilizes discrete joint connections (i.e., noncontinuous haunch) to eliminate blind grouting. The report also presents proposed revisions to the AASHTO LRFD Bridge Design Specifications. The material in this report will be of immediate interest to bridge engineers. |
