Time-dependent reliability of (weighted) k-out-of-n systems with identical component deterioration
Journal of Infrastructure Preservation and Resilience - Tập 2 - Trang 1-10 - 2021
The performance of civil infrastructure systems is vital in supporting a community’s functionalities. Reliability assessment of these systems is a powerful approach to evaluate whether the system performance is desirably safe under the impacts of resistance degradation and non-stationary loads. A k-out-of-n system is a widely-used logic model for a system with n components, which survives (works) ......
Meta-analysis on PET plastic as concrete aggregate using response surface methodology and regression analysis
Journal of Infrastructure Preservation and Resilience - Tập 4 - Trang 1-15 - 2023
This paper aims to thoroughly analyze the effect of polyethylene terephthalate (PET) plastic aggregate on concrete compressive strength using a meta-analysis. Forty-three datasets for concrete containing PET coarse aggregate and 60 data sets for concrete containing PET fine aggregate were collected. The input variables used were percentage and nominal maximum size of PET aggregate along with the c......
Probabilistic analysis of long-term loss incorporating maximum entropy method and analytical higher-order moments
Journal of Infrastructure Preservation and Resilience - Tập 3 - Trang 1-17 - 2022
Quantifying economic losses of civil infrastructures subjected to various hazards under a life-cycle context is of vital importance for risk assessment and management. In previous studies, the expected long-term loss has been widely applied as a standard decision criterion during the life-cycle analysis. However, the expectation may not be informative enough to illustrate uncertainties associated ......
Review of regulation techniques of asphalt pavement high temperature for climate change adaptation
Journal of Infrastructure Preservation and Resilience - Tập 3 - Trang 1-18 - 2022
Asphalt pavement is vulnerable to the temperature rising and extremely high-temperature weather caused by climate change. The regulation techniques of asphalt pavement high temperature have become a growing concern to adapt to climate change. This paper reviewed the state of the art on regulating asphalt pavement high temperature. Firstly, the influencing factors and potential regulation paths of ......
Life-cycle cost analysis of bridges subjected to fatigue damage
Journal of Infrastructure Preservation and Resilience - Tập 2 - Trang 1-13 - 2021
Life-cycle cost analysis (LCCA) is a decision-making tool particularly useful for the design of bridges as it predicts lifetime expenses and supports the inspections management and the maintenance activities. LCCA allows to consider uncertainties on loads, resistances, degradation and on the numerical modelling and structural response analysis. It also permits to consider different limit states an......
Analysis methodology and assessment indices of vulnerability for asphalt pavement in cold regions
Journal of Infrastructure Preservation and Resilience - Tập 2 - Trang 1-14 - 2021
Asphalt pavement structures in cold regions, which suffer from complicated environmental and geological conditions, such as large temperature difference and frozen soil, are prone to cracking, rutting, and moisture damage. However, most of the existing assessment methodologies focus on the vulnerability of the overall road traffic network, ignoring the impact of regional differences and pavements’......
Enclosing contour tracking of highway construction equipment based on orientation-aware bounding box using UAVAbstract Construction equipment tracking of highway construction site can obtain the spatiotemporal location in real time and provide data basis for construction risk control. The complete 2D moving of construction equipment in surveillance videos could be spatially represented by the translation, rotation and size change of corresponding images. To describe the tem... ...

Corrosion of carbon steel rebar in binary blended concrete with accelerated chloride transportAbstract Samples with two different binary blended concrete mixes were prepared, one containing cement replacement of 50% slag (referred here as SL mix) and the other containing cement replacement of 20% fly ash (termed here as FA mix). The water to cementitious ratio used to produce concrete specimens was 0.41. On the top surface of each specimen, various reservoir... ...

A novel random finite element model for holistically modeling of the frost effects on soils and cold region pavements
Journal of Infrastructure Preservation and Resilience - Tập 3 - Trang 1-14 - 2022
This paper describes the development of a random finite element model (RFEM) that allows holistic simulation of frozen soil behaviors, including the effects of phase transition and the consequent internal stress and volume changes. The performance of the model is firstly validated with laboratory experiments. The model is implemented to simulate the effects of frost action on pavement. The coupled......
Probabilistic analysis of climate change impact on chloride-induced deterioration of reinforced concrete considering Nordic climate
Journal of Infrastructure Preservation and Resilience - Tập 3 - Trang 1-16 - 2022
The impact of climate change on the deterioration of reinforced concrete elements have been frequently highlighted as worthy of investigation. This article addresses this important issue by presenting a time-variant reliability analysis to assess the effect of climate change on four limit states; the probabilities of corrosion initiation, crack initiation, severe cracking, and failure of a simply ......
