The root cause analysis included material, metallographic and mechanical property testing; wear observation; micro-zone analysis and mechanism analysis. During the analysis, the primary causes of failure were identified as triple-stress concentration, surface defects, and the aggregation of inclusions .

P c = n.d.t.σ c. When the crushing resistance (P c) is greater than the applied load (P) per pitch length, then this type of failure will occur.How to detemine a Riveted Joint is Safe? We have discussed different failures in Riveted Joints. Also, we determined the resisting force equations P t, P s and P c for each of the Above failures …

2. Fault tree analysis. Fault tree analysis is a systematic safety analysis tool that proceeds deductively from the occurrence of an undesired event (accident) to the identification of the root causes of that event .. Fault tree analysis starts with a "top event" that generally display with rectangular and related events based on logical relations with the top event that are …

The 3 common causes of failure of flexible pavement are as follow. Failure of subgrade; Failure of sub-base or base course; Failure of surface or wearing course; 1. Failure of Subgrade. This is the main cause of flexible pavement failure. When there is excessive deformation in subgrade soil, it will result in failure of whole pavement.

Concrete cast-in-place T-beam highway bridges are often constructed by casting the girders and the deck separately, creating a cold joint between the girders and the deck. Under certain circumstances, cracking and visible slippage can occur in this joint, resulting in fracture of the reinforcing steel crossing the joint, greatly reducing the …
