RIS3D Grain-Based Mesoscale Modeling of Short Fatigue Crack Growth for Bridge Weldments Considering Crack-Front Evolution
Publisher: ASCE
Abstract: To evaluate short crack growth and fatigue damage accumulation in steel structures, efforts have been made based on a two-dimensional (2D) grain-based model for fatigue life assessment under variable amplitude loads. ...
Identification of Critical Causes of Tower-Crane Accidents through System Thinking and Case Analysis
Publisher: ASCE
Abstract: Tower-crane accidents occur frequently and often have serious consequences. To identify the critical causes of tower-crane accidents, this study adopted a method that combined system thinking and case analysis. The entirety ...
Experimental Study on Continuous Bridge-Deflection Estimation through Inclination and Strain
Publisher: ASCE
Abstract: When monitoring structural data, incompleteness is a crucial issue that affects structural health monitoring (SHM). Information on displacement is particularly important for bridge state estimation, but it is difficult to ...
Quantification of Fatigue Damage for Structural Details in Slender Coastal Bridges Using Machine Learning-Based Methods
Publisher: ASCE
Abstract: Exposed to the challenging coastal environment, slender bridges could experience significant dynamic responses and complex stress states resulting from the coupled dynamic impacts of wind, wave, and vehicle loads. Cracks ...
Fatigue Life of Weldment Details of Existing Orthotropic Steel Bridge Considering the Scour Effects
Publisher: ASCE
Abstract: During the service life of the orthotropic steel bridges (OSBs), fatigue damage accumulations could impact the safety and reliability of the bridges in their lifecycles. Fatigue damage evaluations of bridge weldments for ...
Deployment Dynamics for a Flexible Solar Array Composed of Composite-Laminated Plates
Publisher: ASCE
Abstract: Modern spacecraft often deploy large-scale and lightweight solar arrays consisting of composite-laminated plates because of their high reliability, superior mechanical properties, and low manufacturing cost. This paper ...
Atomistic Simulation of Short Crack Growth in Correlation with Fatigue Indicator Parameter
Publisher: ASCE
Abstract: Under time-varying extreme dynamic environmental conditions, fatigue damage could gradually accumulate with increased stress cycles at critical details of steel or other metallic structures. As a promising tool, a fatigue ...
Laboratory Performance Evaluation of a Waterborne Epoxy-Modified Asphalt Mixture with Styrene-Butadiene Rubber for Cold Patching Applications
Publisher: ASCE
Abstract: Cold mix asphalt (CMA) is commonly used for repairing asphalt pavement potholes. Ordinary CMA has the problems of poor construction workability and low initial strength in low-temperature environments. To improve pothole ...
Numerical Modeling of Response of CFRP–Concrete Interfaces Subjected to Fatigue Loading
Publisher: ASCE
Abstract: For interfaces between externally bonded fiber-reinforced polymer (FRP) laminates and concrete, the incremental fatigue analysis for each load cycle using a finite-element (FE) model is exceptionally time-consuming. This ...
Assessment of Diagonal Macrocrack-Induced Debonding Mechanisms in FRP-Strengthened RC Beams
Publisher: ASCE
Abstract: This study presents a numerical model to characterize the fracture process of a reinforced concrete (RC) beam strengthened with fiber-reinforced polymer (FRP) in detail. A numerical model based on the application of cohesive ...
