concrete hingeconcrete hinge with front side notches
Concrete hinges are hinges produced out of concrete, with no or almost no steel in the hinge neck, which allows a rotation without a relevant bending moment.[1] This high rotations[2][3] are resulting from controlled tensile cracks as well as creep.[4][3][1] Concrete hinges are mostly used in bridge
engineering[1] as monolithic, simple, economic alternative to steel hinges, which would need regular maintenance. Concrete hinges are also used in tunnel engineering.[1][3] A concrete hinge consist of the hinge neck, which has a reduced cross section and of the hinge heads, which have a strong reinforcement.[3][1][5]
