ABSTRACT:
A support structure, such as a bridge support structure for long spans between supports, includes a beam-like girder formed of reinforced concrete or prestressed concrete connected to and supported on the upper ends of support piers so that the girder is bending resistant. A strut framework extends between the girder and the support pier and includes a reinforced concrete compression strut extending diagonally upwardly from the lower end of the support pier to the girder at a position spaced outwardly from the support pier whereby the dead load of the compression strut is supported by tie rods extending from the compression strut upwardly to the girder or the pier. The compression strut forms one side of a triangle with the other sides formed by the girder and the support with the tie rods located within the triangle.
