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 ...
Corrosion of carbon steel rebar in binary blended concrete with accelerated chloride transport
Journal of Infrastructure Preservation and Resilience -
AbstractSamples 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 lengths that ranged from 2.5 cm
...
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...
Enclosing contour tracking of highway construction equipment based on orientation-aware bounding box using UAV
Journal of Infrastructure Preservation and Resilience -
AbstractConstruction 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 temporal relationships of these
vari...
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 ...
Numerical analysis on seismic behavior of the assembled modular steel plate shear wall with inclined slots
Journal of Infrastructure Preservation and Resilience - Tập 4 Số 1
AbstractThis paper proposes a novel multi-grids steel plate shear wall with
inclined slots (called MSPSW). This MSPSW composed of the steel plates with
inclined slots, precast concrete panels, the transverse and longitudinal (T&L)
connecting stiffeners, and external frame components. Smaller single plates can
be used in the design and installation process since the space size of
individual frames ...
Gene-editable materials for future transportation infrastructure: a review for polyurethane-based pavement
Journal of Infrastructure Preservation and Resilience - Tập 2 Số 1
AbstractWith the rapid development of society and industry, novel technologies
and materials related to pavement engineering are constantly emerging. However,
with the continuous improvement of people’s demands, pavement engineering also
faces more and more enormous challenges that the pavement materials must have
excellent engineering properties and environmental benefits. Meanwhile, the
intellig...
