Abstract

Throughout the nation there are a number of bridges that for one reason or another, are posted for lower than original design loads. In many cases the proper strength rating of a bridge cannot be achieved by the present methods of analysis. In most cases the bridge is small and may be on an off system road so that it doesn't seriously impact the commercial users. This paper presents the nondestructive method used in Florida for evaluating the strength of existing bridges. The method allows a satisfactory overall strength evaluation of any bridge under question. The experience gained from these tests indicate that load limitations imposed by theoretical analyses are not representative of the structures' real capacities. Proof loading has consistently indicated that structures have greater residual strength. The paper illustrates the use of bridge load testing as a tool for nondestructive evaluation of old or newly constructed prestressed concrete bridge. The load testing procedure, data acquisition, and evaluation of two bridges are presented.
