STRUCTURE EVALUATION SUMMARY

This weathering steel truss pedestrian bridge is in poor condition overall due to deterioration of the floor beams and interior stringers. Significant section loss led to the immediate notification to the park to restrict the structure to pedestrian loading only, with the recommendation to install bollards at each end to ensure compliance. Close monitoring and/or supplemental supports will be required to keep even pedestrian access on this structure for the near term.

The timber deck has moderate decay throughout and is retaining excessive moisture; this appears to be the mechanism allowing the floor beams and stringers to continue to corrode. Thorough cleaning of heavy rust scale from 6 representative floor beams and their adjoining stringers revealed that floor beam flange thicknesses were reduced to 1/16” (7/16” original thickness) with flange tips down to a knife edge at some locations. Web thicknesses were reduced to between 1/32” and 1/16” (original thickness could not be determined) with up to fifteen 2” diameter holes rusted through observed in a single floor beam. Stringer flange thicknesses were reduced to 1/8” (1/4” original thickness) with flange tips down to a knife edge at some locations. Stringer web thicknesses were reduced to between 1/32” and 1/16” (original thickness could not be determined) with up to 4” long x 3” high scattered holes rusted through.

STRUCTURE SUMMARY STRUCTURE NO. 6160-040S

STRUCTURE EVALUATION SUMMARY CONTINUED

Exterior stringer and lower lateral bracing angles have more moderate corrosion and section loss with a consistent ¼” thickness remaining (3/8” original section). Minor section loss was observed along the bottom chord, and to the verticals, diagonals, and gusset plates at the lower panel point connections where debris accumulates and retains moisture. Drain holes in the vertical members were all clogged at these locations. Minor section loss was also observed at the bottom chord splices where dirt and corrosion product accumulate and at the top of the top chord splices where water ponds (no drain holes exist in top chord members).

Repairs should be made as outlined in this report to prevent the possible development of more serious or costly problems in the future.

RECOMMENDATIONS AND ESTIMATED COSTS STRUCTURE NO. 6160-040S

A (Critical) - Structure is closed, in imminent danger of collapse, or presents a critical safety hazard.

B (Major) - Structure is seriously deficient or presents a safety hazard, but can remain in service at reduced loads or with frequent inspections.

C (Moderate) - Structure is deficient, functionally obsolete, or requires substantial repairs to prevent a serious deficiency or unsafe condition.

D (Minor) - Structure is generally in good condition. Preventative maintenance may be required.

E (Special) - Structure is under construction or reconstruction.

CONDITION RATING CODES FOR ITEMS 58 - 62, 222, 223

N NOT APPLICABLE 3 SERIOUS CONDITION - loss of section, deterioration, spalling, or scour have seriously affected primary structural components. Local failures are possible.

9 EXCELLENT CONDITION Fatigue cracks in steel or shear cracks in concrete may be present.

8 VERY GOOD CONDITION - no problems noted. 2 CRITICAL CONDITION - advanced deterioration of primary structural elements. Fatigue cracks in steel or shear cracks in concrete may be present

7 GOOD CONDITION - some minor problems. or scour may have removed substructure support. Unless closely monitored it may be necessary to close the structure until corrective action can be taken.

6 SATISFACTORY CONDITION - structural elements show some minor deterioration. 1 “IMMINENT” FAILURE CONDITION - major deterioration or section loss present in critical structural components or obvious vertical or horizontal

5 FAIR CONDITION - all primary structural elements are sound but may have movement affecting structure stability. Structure is closed to traffic but minor section loss, cracking, spalling, or scour. corrective action may return structure to light service.

4 POOR CONDITION - advanced section loss, deterioration, spalling, or scour. 0 FAILED CONDITION - out of service; beyond corrective action.
