REPAIR OF POPLAR STREET COMPLEX BRIDGES IN EAST ST. LOUIS

The web cracks found in the Poplar Street Complex Bridges were located at the top of the web-to-bottom flange fillet weld near the end floor beams. The buckled web was observed at the end of the girders behind the bearing stiffener. This report summarizes the results of the study which intends to determine the proper causes of the distress. It is believed that the main cause of the web crack was due to the out-of-plane movement of the web; and that the cause of the web buckling was from the eccentric reaction induced by the seized bearing pin. The repair method was developed mainly to stiffen the section and to carry the secondary stress induced from the out-of-plane movement of the web and to resist the distortion of the girder due to differential deflection of the main girders. Suggested details for future design are also included. /Author/
