ABSTRACT:
An arch is formed of prefabricated reinforced concrete shells connected at the arch apex by an on-site cast concrete joint is built as a skewed underpass structure. In order to avoid complicated edge elements or a costly lengthening of the underpass, the individual reinforced concrete shells are formed to have their horizontal projection (in the horizontal projection of an assembled underpass) define a parallelogram which includes at least one acute angle which correspond to the acute angle formed by the intersection of the axis of the overpass traffic route with the axis of the underpass traffic route. Thus, edge elements are not necessary. An apex joint is formed of on-site cast concrete. Reinforcement rods extend into the apex joint and are arranged in an asymmetrical manner so that all elements can be designed and reinforced in the same manner with the reinforcement rods in the joint meeting directly.
