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) ......
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 ......
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’......
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 ......
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......
Risk-averse rehabilitation decision framework for roadside slopes vulnerable to rainfall-induced geohazards
Journal of Infrastructure Preservation and Resilience - Tập 3 - Trang 1-13 - 2022
Rainfall-induced slope failures disrupt the traffic and warrant urgent slope repair works. The impact of roadside slope failures can be minimized if slopes are proactively rehabilitated. Nonetheless, transportation agencies are constrained in their budget to rehabilitate a limited number of slope segments due to competing maintenance needs among different transportation assets. Therefore, the tran......
Resilience modeling concepts in transportation systems: a comprehensive review based on mode, and modeling techniques
Journal of Infrastructure Preservation and Resilience - Tập 1 - Trang 1-20 - 2020
The objective of this comprehensive review study was to compile a state-of-the-art understanding of the resilience of the transportation system due to natural and man-made disasters. This study identified resilience measurement parameters that can be used to formulate resilience quantification and improvement strategies of a transportation system. Reviewed articles were classified and summarized f......
Coastal green infrastructure to mitigate coastal squeezeAbstract Infrastructure is necessary to protect and provide the goods and services required by humans. As coastal green infrastructure (CGI) aims to respect and work with natural processes, it is a feasible response to mitigate or avoid the consequences of coastal squeeze. The concept of CGI is receiving increased attention of late due to the challenges facing us, s... ...

Emerging steel frames with Fe-SMA U-shaped dampers for enhancing seismic resilience
Journal of Infrastructure Preservation and Resilience - Tập 4 - Trang 1-21 - 2023
Post-earthquake financial loss of structures induced by residual inter-story deformation (RID) has been recently noticed and various strategies have been proposed. A newly-emerged energy-dissipation material, namely, iron-based shape-memory-alloy (Fe-SMA), has gain favor in civil engineering community due to its extraordinary low-cycle fatigue resistance property. Besides, Fe-SMA is believed to he......
