Studies on non-destructive inspection of steel wire ropes
Abstract: Non-destructive tests (NDT) of steel wire ropes under services are experienced to estimate remnant life with reference to new and similar components tested under similar conditions. Inspection by magnetic defect-stray fields’ to gamma radiography for imaging defects in addition, for suspended bridges have been methods of tests to configure defect morphologies in wires. This is beyond standard periodic inspections accounted from constrains of pre broken wires, multi-axial deformation, frictional wear, …

Analysis of Box Culvert with Different Aspect Ratio
Abstract: Box culverts are the default buried structure type, where pipe solutions are not suitable. Their larger openings are often required to provide adequate hydraulic capacity. Box culverts are also frequently used for pedestrian or cattle underpasses. The reinforcement used in concrete box culverts can be either conventional bar reinforcement or welded wire fabric. Welded wire fabric has yield strength slightly larger than conventional bar reinforcement. Standard designs for precast concrete …
