Project Objective | The objective of the rehabilitation program of the West 7th Street Bridge in Fulton, MO is to remove the 15 Ton load posting that has been imposed on it. The structural analysis has demonstrated that to achieve this objective the shear and flexural capacities of the superstructure system (i.e. arch ribs, columns and transversal beams) need to be upgraded. In addition, large cracking is observed in the abutments due to earth pressure, which necessitates the undertaking of remedial measures. |

Project Abstract | The West 7th Street Bridge was built in the 1910's. The bridge structure has a span of 64.2 ft and a rise of 10.4 ft. With regard to the boundary conditions, the bridge can be classified as a two-hinge less RC arch rib, whereas in accordance with the method of supporting the structure, it can be classified as an open spandrel arch, where the loads from the deck are transmitted to the arch by means of transversal beams and columns. The original deck was replaced in the 1970's. The new concrete was cast on trapezoidal-type corrugated steel sheets running in the direction of traffic. The abutments transmit the reaction from the superstructure to the foundation and retain the earth embankment of the approach roadway. Their type corresponds to typical gravity abutments with wing walls.
This project consists of: a) the field and laboratory investigations necessary to validate the assumptions to be made for design of the strengthening, b) analysis of the existing substructure and superstructure; and c) design of the upgrade. |
