Abstract This paper presents a reliability-based methodology for failure assessment of reinforced rock slopes subjected to bolt corrosion. Strength failure of the rock bolt, bond failure between the rock bolt and the grout and bond failure between the rock and the grout are considered and their load effects are treated as stochastic processes. The failure probability of each failure mode was evaluated using first passage probability, in which two auto-correlation functions are considered for the...

Field evidence revealed that buried cast iron water pipes can deteriorate through large localized corrosion patches with lengths greater than 1 m, formed by a cluster of small pits. This study inve...

Aging infrastructure such as water pipelines is a growing problem that will require urgent solutions within the next few decades. These pipeline assets have been in service beyond their designed service live (50 years) and failures are inevitable. Therefore, water utilities are seeking strategic pipe replacement techniques to prioritise their limited budget and proactive failure prevention methods to avoid catastrophic, costly pipe failures. In this paper, the process of a leak initialising from...

Abstract At present, a significant proportion of Australia’s ageing water infrastructure is composed of cast-iron pipes. The corrosion of cast-iron pipes is the main triggering factor for Australia’s water industry. It has been found that the failure mode of small diameter water mains (

AbstractA review of the literature shows that current research on corrosion-affected reinforced concrete structures focuses more on strength deterioration than on serviceability deterioration. For ...

This paper presents a reliability-based methodology for assessing fracture failures of steel pipes with sharp corrosion pits. Based on newly developed models of elastic fracture toughness, the simple criterion of stress intensity factor (SIF) is used to establish the limit state functions for pipes with sharp corrosion pits in the longitudinal and circumferential directions. A stochastic model of load effect is developed and a time-dependent reliability method based on first passage probability ...

Abstract This paper presents a methodology for determining the probability of system failure of corrosion affected steel pipelines with multiple failure modes. The failure modes include fracture, strength failure, deflection and buckling and they are all modelled as stochastic processes with correlations among them. The first passage probability theory is employed to quantify the probability of pipe failure. A case study is presented to illustrate the proposed methodology, followed by a sensitiv...

Practical experience and observations suggest that corrosion affected reinforced concrete (RC) structures are more prone to cracking than other forms of structural deterioration. Once a crack initiates at the steel-concrete interface, it will propagate to a critical depth at which the crack becomes unstable and suddenly propagate to the concrete surface. This paper aims to develop an analytical method to predict the critical crack depth in corrosion-induced cracking of reinforced concrete struct...
