AbstractConcrete cover cracking caused by reinforcement corrosion is a significant durability problem of reinforced concrete (RC) structures. Extensive research has been carried out in the last few decades while most were focused on corrosion of a single reinforcing bar. Very little research has examined the whole cover cracking of RC structures due to multiple reinforcement corrosion. This article develops a numerical model to predict the structural failure of the whole cover of concrete induce...

A climate-responsive landscape design can create a more livable urban microclimate with adequate human comfortability. This paper aims to quantitatively investigate the effects of landscape design elements of pavement materials, greenery, and water bodies on urban microclimate and thermal comfort in a high-rise residential area in the tropic climate of Singapore. A comprehensive field measurement is undertaken to obtain real data on microclimate parameters for calibration of the microclimate-mod...

A review of published literature on the corrosion of metal pipes reveals that current research on corrosion of full-size pipe sections in real soil conditions is highly limited, with almost no research reported on the corrosion effect on degradation of mechanical properties, and fracture toughness in particular, of cast iron pipes buried in real soil. This paper presents a new testing methodology for investigating the corrosion of cast iron pipes in real soil and evaluating its effect on the deg...

Corrosion of steel is a worldwide issue which potentially affects structural integrity of bridges. This research presents the results of comprehensive lab tests on the stress effect on corrosion and the combined effect of stress and corrosion on the mechanical properties of steel bridge elements. G250 mild steel specimens, commonly used for bridge construction, are used for analysis. Both stressed and non-stressed specimens are immersed in acid solutions to simulate corrosion progress. The stres...

This paper presents a time-dependent reliability method for the assessment of corrosion-affected metal pipe failures. Two nonlinear limit state functions are proposed for brittle and ductile pipes with mixed mode fracture. For brittle materials, a general failure criterion taking into account all three fracture modes is adopted, whereas for ductile materials, the criterion of stress intensity factor is used, based on a newly developed model of elastic fracture toughness. Stochastic models of cor...

The flow of water into a tunnel, through the surrounding rock mass and the tunnel lining, has important implications for tunnel design and tunnel condition assessment. The hydraulic conductivity of the lining is a major controlling factor on the water inflow rate. Previous work had been mainly based on the assumption of constant hydraulic conductivity of the lining. In this work, the existing analytical models of water flow through a tunnel lining under steady-state, saturated conditions are ext...

Abstract Mixed mode fractures can be triggered by either multi-axial stresses or inclined cracks or both. Little research has been undertaken on J-integral for inclined surface cracks in plates under biaxial loading. This paper intends to determine the elastic and fully plastic J-integral for mixed mode fracture induced by inclined surface cracks in plates under biaxial loading conditions, using three-dimensional finite element method. Various geometries, biaxiality and material properties of cr...

Abstract Underground pipes are essential infrastructure for water, oil and gas transport. The presence of localized pitting corrosion has been identified as one of the main deterioration mechanisms for metal pipes, which, when exposed to external loadings, can easily fail due to intensified stresses at the corrosion pit. The assessment of such an intensified stress field around the pit has been a key focus for decades since it is a major mode of pipe failures. Although stress intensity factors f...

As an essential infrastructure tunnels play an important role in transport network. The functionality of this infrastructure depends on its structural and durability performance. In the climate of an increasing scarcity of resources, infrastructure maintenance is becoming increasingly important. This paper aims to develop a maintenance strategy for tunnels, which determines when, where and what to maintain, to ensure the safe and serviceable operation of tunnel structure with the intention to mi...

The increasing rate of deterioration of buried pipelines has necessitated the development of a robust assessment method for their structural integrity and service life prediction. Among various deterioration mechanisms, ductile iron pipes are most prone to pitting corrosion and subsequent leakages. This paper intends to develop a methodology to predict the perforation induced by pitting corrosion on buried ductile pipes. The methodology integrates the random fields, gamma process, and copulas in...
