Abstract:

During the construction of the I-295 cable-stayed bridge, a number of the stays on the main span cantilever were instrumented with electrical resistance strain gages mounted directly on the wires of the seven-wire strands making up the stay cables. Measurements were taken beginning before tensioning and continuing until completion of the cantilever. Expected changes in the strains caused by lifting of segments and subsequent stay tensioning activities were observed. During the multistrand tensioning activities on the instrumented stays, significant variability in the strain behavior of the individual strands was observed, a fact that should be considered in the design of cable-stay systems and tensioning methods.
