(ASCE, 8/1/2020 1)A series of seismic centrifuge tests were performed on an RC girder-type bridge with a 3 × 3 pile-group foundation embedded in dry sand to investigate the seismic behavior under various scour conditions. Based on the ... -
Investigation of Temperature Effects on Steel-Truss Bridge Based on Long-Term Monitoring Data: Case Study
(ASCE, 9/1/2020 1)The time-varying average and differential temperatures may significantly change the performance of steel truss bridges, which may increase the difficulties for bridge design, construction, and maintenance. Because hundreds ... -
Crack Propagation-Based Fatigue Life Prediction of Corroded RC Beams Considering Bond Degradation
(ASCE, 8/1/2020 1)Corrosion increases the nominal stress of reinforcing bars and accelerates the fatigue crack propagation. The stress redistribution induced by bond degradation between concrete and rebars makes the fatigue life prediction ... -
Full-Scale Experimental Study on Vibration Control of Bridge Suspenders Using the Stockbridge Damper
(ASCE, 8/1/2020 1)The Stockbridge damper (SD) has been used for vibration mitigation of suspender cables subjected to vortex-induced and other types of resonant vibrations. This paper studies its effectiveness and robustness, as well as a ... -
Factors Affecting Loss in Durability in Prestressed-Concrete Girders with Microcracking
(ASCE, 9/1/2020 1)Early-age unexplained cracking in concrete structures is always a concern, as this signals the occurrence of uncontrolled volumetric changes. A study to investigate the effects of early-age microcracks on the service life ... -
Frictional Resistance between Main Cable and Saddle for Suspension Bridges. I: Friction Characteristic of Single Strand
(ASCE, 8/1/2020 1)The frictional resistance between main cable and saddle of a long-span, multispan suspension bridge is significant for the safety of the bridge. Typically, the main cable of a long-span, multispan suspension bridge has ... -
Outdoor Test of a Prefabricated Column–Pile Cap–Pile System under Combined Vertical and Lateral Loads
(ASCE, 8/1/2020 1)An outdoor test was conducted on a prefabricated column–pile cap–pile system at a cohesive soil site. The half-scale test unit consisted of a precast bridge column, a precast pile cap, and eight steel piles. The components ... -
Postflutter Analysis of Bridge Decks Using Aerodynamic-Describing Functions
(ASCE, 8/1/2020 1)An aerodynamic describing function (ADF)-based model for simulating the nonlinear self-excited forces on bridge decks is developed, where the ADFs can be conveniently identified using the experimentally or numerically ... -
Experimental Demonstration of a Mode Shape-Based Scour-Monitoring Method for Multispan Bridges with Shallow Foundations
(ASCE, 8/1/2020 1)This paper experimentally investigates a vibration-based scour monitoring approach applicable to bridges with multiple simply supported spans on shallow foundations. A monitoring strategy based on the relative changes in ... -
Evaluation of Pretensioned Girders with Partial-Strand Debonding
(ASCE, 8/1/2020 1)Pretensioned concrete girders—especially those having large prestress forces—are susceptible to flexural cracking at their top flanges near the girder end as a result of prestress transfer. One effective method to reduce ... -
Improvement of Flutter Performance of a Streamlined Box Girder by Using an Upper Central Stabilizer
(ASCE, 8/1/2020 1)Streamlined box girders are widely used when designing long-span bridges owing to their aerodynamic and aerostatic stability. However, the flutter performance of this type of girder requires improvement when they are ... -
Overlap of Splitting in Slabs with Closely Spaced Intermediate Anchorages
(ASCE, 8/1/2020 1)Slab splitting, resulting from the dispersion of a number of intermediate loads arranged in a line, is a common problem in such engineering structures as steel–concrete composite girders and pylon anchorages of cable-stayed ... -
Pedestrian-Induced Vibrations of Footbridges: An Extended Spectral Approach
(ASCE, 8/1/2020 1)The vibration serviceability assessment of footbridges under pedestrian traffic requires a probabilistic approach considering the uncertainty in the dynamic behavior of the structure and the variability of multiple load ... -
