Reliability of Parallel Wire Cables for Suspension Bridges

Measurement of Strain/Load Transfer in Parallel Seven-wire Strands with Neutron Diffraction

“…Similar studies can yield insight into the strain partitioning in strands prepared with different conditions. A systematic study of load sharing in wire rope and bridge cable assemblies will yield valuable data for testing and improving analytical calculations [3,17] and finite-element models [18,19]. Such results would also contribute to the evaluation of the load carrying capabilities of existing suspension-bridge cables, and to the design of new bridge cables.…”

“…The strand ends were inserted into conical socket assemblies [9] machined from commercially available universal joints (Curtis CJ653). 3 The individual wires were then broomed (splayed) out [ Fig. 2(b)], and the sockets filled with a commercially available socket epoxy.…”

“…Analysis of load partitioning within such cables is a nontrivial problem [1,2] and poses theoretical [3] and experimental challenges [4][5][6]. The cable can be considered as a massive fiber composite structure that is loaded in the far field.…”

Fatigue failure analysis of stay cables with initial defects: Ewijk bridge case study

“…[1][2]. Models have been put forward in literature for the assessment of parallel wire cables with fractured wires.…”

“…The test showed no wire fractures after applying a variable amplitude spectrum with stress ranges and number of cycles representing the traffic between 1972 and 1990. The test was then continued with a constant amplitude range of 200 N/mm 2 [18]. A calculation using the stress spectrum of Fig.…”
