PHOTOELASTIC MODEL OF BRIDGE CROSS-FRAME JUNCTION

During the construction of the Bryte Bend Bridge on Interstate 880 near Sacramento, Calif., a crack developed in the main flange. A photoleastic model was constructed and analyzed to determine experimentally the prevailing stresses. The stress at the weld connecting the cross-frame strut to the main flange, where the crack originated, was measured. The results indicate that the welding of the strut produced a change in geometry, creating a threefold increase in the stress, when compared to the unwelded design. /Author/
