RISAdaptation Optimization of Residential Buildings under Hurricane Threat Considering Climate Change in a Lifecycle Context
Publisher: American Society of Civil Engineers
Abstract: Due to urbanization, the number of residential buildings in coastal areas has increased significantly. Additionally, due to the increase in sea surface temperature associated with climate change, the intensity and frequency ...
Probabilistic Time-Dependent Multihazard Life-Cycle Assessment and Resilience of Bridges Considering Climate Change
Publisher: American Society of Civil Engineers
Abstract: Climate change and an increase in the number of hazards and/or their intensities may increase the probability of failure associated with civil infrastructure systems. Understanding how natural hazards affect the life-cycle ...
Assessment of Risk Using Bridge Element Condition Ratings
Publisher: American Society of Civil Engineers
Abstract: In this paper, a methodology for quantifying lifetime risk of bridge superstructures is presented. The risk is quantified in terms of the expected direct and indirect losses. A scenario-based approach, which uses the
Life-Cycle Cost Analysis of Deteriorating Civil Infrastructures Incorporating Social Sustainability
Publisher: ASCE
Abstract: Social sustainability has rarely been considered in the design and management of civil infrastructures. This paper presents a two-level, six-category classification of social impacts regarding civil infrastructures and the ...
Time-Dependent Reliability and Redundancy of Corroded Prestressed Concrete Bridges at Material, Component, and System Levels
Publisher: American Society of Civil Engineers
Abstract: Due to structural deterioration, the performance of concrete bridges degrades with time and may result in catastrophic failure events, especially for nonredundant structures. This paper develops a methodology for assessing ...
Time-Dependent Reliability Analysis Based on Point-Evolution Kernel Density Estimation: Comprehensive Approach with Continuous and Shock Deterioration and Maintenance
Publisher: ASCE
Abstract: Civil infrastructure may degrade due to the adverse effects of continuous damage (e.g., reinforcement corrosion) and sudden shocks (e.g., earthquakes) during its service life. Many studies have been conducted in ...
Sustainable Life-Cycle Maintenance Policymaking for Network-Level Deteriorating Bridges with a Convolutional Autoencoder–Structured Reinforcement Learning Agent
Publisher: ASCE
Abstract: Bridges play a significant role in urban areas, and their performance and safety are highly related to the carbon emissions of infrastructure systems. Previous studies have mainly offered maintenance policies that balance ...
Accelerated Construction of Self-Anchored Suspension Bridge Using Novel Tower-Girder Anchorage Technique
Publisher: American Society of Civil Engineers
Abstract: The traditional construction methods (e.g., erecting cable after girder) of the self-anchored suspension bridge can interrupt traffic during the construction stage due to the installation of temporary supports. That severely ...
Accelerated Construction of Self-Anchored Suspension Bridge Using Novel Tower-Girder Anchorage Technique
Publisher: American Society of Civil Engineers
Abstract: The traditional construction methods (e.g., erecting cable after girder) of the self-anchored suspension bridge can interrupt traffic during the construction stage due to the installation of temporary supports. That severely ...
Nonstationary Turbulent Wind Speed Models and Their Effects on Wind-Induced Responses of Tall Buildings
Publisher: American Society of Civil Engineers
Abstract: There exist so many approaches to extract the time-varying mean (TVM) of nonstationary wind speeds under the nonstationary wind speed model, such as the wavelet transform and empirical model decomposition. These approaches ...
