Description
Usually, many of the large box culverts with over 5m width are skewed, and in-situ concrete is used from the viewpoint of economic efficiency. However, precast concrete products can shorten a period of construction work and keep uniform quality. In this study, an economical precast concrete box culvert which could be applied for skew structures was developed. Top plate and side wall were segmented and both were connected by looped joint connection on the corner. First of all, the element experiment on looped joint connection system was conducted. After that, the full-scale specimen was assembled, and then construction performance and structural performance were investigated. As the results, the box culvert could be assembled as it was expected, and it had equivalent structural performance to the ordinary box culvert using in-situ concrete. Also, in order to the calculate stress resultant of large-scale box culvert, the method considering the rigid frame on elastic foundation was preferable.
