RISLongitudinal Seismic Response of Underground Pipelines Subjected to Multiple-Supported Random Ground Excitations
Publisher: ASCE
Abstract: For long-span structures, such as long bridges and underground pipelines, the loss of correlation of ground movements during an earthquake should be taken into account for seismic analyses. In this paper, longitudinal ...
Stress Evaluation for Rocks and Structural Concrete Members through Ultrasonic Wave Analysis: Review
Publisher: American Society of Civil Engineers
Abstract: The preferable way to monitor structural behavior is to measure the actual stress in the structural members. Unfortunately, stress relieving by cutting holes or slots has been the only method applicable to date for measuring ...
Residual Service Life Prediction for Bridges Based on Critical Life Curves

Fatigue Behavior of Stirrup Free Reactive Powder Concrete Beams Prestressed with CFRP Tendons
Publisher: ASCE
Abstract: A comprehensive study on the fatigue behavior of stirrup free reactive powder concrete (RPC) beams prestressed with carbon fiber-reinforced polymer (CFRP) tendons is presented in this paper. A total of six specimens were ...
Static Performance of a Long-Span Concrete Cable-Stayed Bridge Subjected to Multiple-Cable Loss during Construction
Publisher: ASCE
Abstract: To study the structural response of a long-span cable-stayed bridge to cable loss during construction, the static performance of the Chishi Bridge subjected to multiple-cable loss caused by a fire accident was investigated ...
Ductile Fracture Characterization of A36 Steel and Comparative Study of Phenomenological Models
Publisher: ASCE
Abstract: To better predict ductile fracture (DF) of structural steels under complicated stress states, the DF of an A36 steel was experimentally and numerically investigated within a wide range of stress states. Meanwhile, a scanning ...
Concrete Damage Evolution and Three-Dimensional Reconstruction by Integrating CT Test and Fractal Theory
Publisher: American Society of Civil Engineers
Abstract: Computerized tomography (CT) scanning is one of the most effective techniques used in studying concrete crack initiation and propagation. CT scanning of concrete under uniaxial compression was used to monitor the ...
Response of Underground Pipelines Subjected to Partially Coherent Seismic Excitation
Publisher: American Society of Civil Engineers
Abstract: Analyses on the basis of seismic array records have confirmed that spatially distributed earthquake ground motions are neither fully coherent nor independent, but partially coherent. It has not yet been fully addressed how ...
Pavement Rut Depth Prediction for a Three-Span Suspension Steel Box Girder Bridge Based on Two-Year Temperature Monitoring Data
Publisher: ASCE
Abstract: The paper presents a study of temperature distribution and effect on the asphalt pavement of the Fourth Nanjing Yangtze River Bridge based on the 2-year continuous monitoring data. The temperature distribution model was ...
Diffusion Coefficient Estimation and Its Application in Interior Change Evaluation of Full-Size Reinforced Concrete Structures
Publisher: American Society of Civil Engineers
Abstract: Diffuse waves have been proved to be more sensitive to medium interior changes than direct waves due to much longer traveling path and propagation time in media. This makes diffuse waves a useful tool in nondestructive ...
