Effects of Partial-Design-Strength Concrete on the Seismic Performance of Concrete-Filled Tube Columns in Accelerated Bridge Construction
(American Society of Civil Engineers, 2016)This study evaluated the seismic performance of circular concrete-filled tube (CCFT) columns in accelerated bridge construction (ABC). In these projects, the bridge should be open to service after a couple of days. For ... -
Time-Variant Risk Assessment of Bridges with Partially and Fully Closed Lanes due to Traffic Loading and Scour
(American Society of Civil Engineers, 2016)This article presents an approach for assessing time-variant risk associated with the closure of bridge lanes due to traffic loading and scour. Scenarios of lane closure are identified for both traffic loading and scour. ... -
Numerical and Experimental Evaluation of the Dynamic Performance of a Footbridge with Tuned Mass Dampers
(American Society of Civil Engineers, 2016)This article presents an evaluation of the dynamic behavior of a slender steel footbridge before and after the installation of two tuned mass dampers (TMDs). The results of the experimental study show that the damping ... -
Human-Induced Vibrations on Two Lively Footbridges in Milan
(American Society of Civil Engineers, 2016)This article describes the results of extensive full-scale experiments carried out on two lively footbridges recently built in Milan, Italy. The objective of the study was to assess the dynamic characteristics of the bridges ... -
Hybrid Sensor-Camera Monitoring for Damage Detection: Case Study of a Real Bridge
(American Society of Civil Engineers, 2016)This article presents the real-world implementation of a novel monitoring system in which video images and conventional sensor network data are simultaneously analyzed to detect possible damage on a movable bridge. The ... -
Reduced Models for Simulating Collisions between Trucks and Bridge Piers
(American Society of Civil Engineers, 2016)Finite-element simulations were used to investigate the structural demands generated by a truck colliding with a bridge pier. A reduced coupled mass-spring-damper model is proposed to simulate the collision process. The ... -
Effects of Bridge Accessories in Steel–Concrete Composite Railway Bridges in Service Condition
(American Society of Civil Engineers, 2016)Bridge accessories, such as parapets, service ducts, and track slabs, are commonly used in railway bridges, but their real effects on the structural behavior of the bridges are still unknown because very few studies have ... -
Retrofit of Built-Up Steel Columns: Modeling and Fundamental Behavior
(American Society of Civil Engineers, 2016)Cover plates are often added to built-up steel columns as an effective retrofit method for increasing strength. For retrofitted columns, the original member carries all loads, whereas the added cover plates resist only the ... -
Extraction of Bridge Frequencies from a Moving Test Vehicle by Stochastic Subspace Identification
(American Society of Civil Engineers, 2016)The technique for extracting bridge frequencies from a moving vehicle was proposed only recently. However, its efficacy may be reduced by road-surface roughness. To this end, the stochastic subspace identification (SSI) ... -
Vehicle Impact on the Deck Slab of Concrete Box-Girder Bridges due to Damaged Expansion Joints
(American Society of Civil Engineers, 2016)Expansion joints will experience increasing deterioration and damage under repeating vehicle loading. A severely damaged expansion joint will induce significant dynamic vehicle load effects on the bridge deck near the ... -
Cyclic Loading Test of Unbonded and Bonded Posttensioned Precast Segmental Bridge Columns with Circular Section
(American Society of Civil Engineers, 2016)Four 1/4-scale precast segmental bridge columns (PSBC) with different reinforcement types and arrangements and one monolithic reference column (MRC) were designed and tested under cyclic quasi-static loading. Both UPC (PSBC ... -
Using Buckling-Restrained Braces on Long-Span Bridges. I: Full-Scale Testing and Design Implications
(American Society of Civil Engineers, 2016)Using the Vincent Thomas Bridge (VTB) as a feasibility case study, near-fault loading protocols for qualifying buckling-restrained braces (BRBs) for use on long-span bridges were developed and are presented in a companion ... -
Flexible Pile Head in Jointless Bridges: Design Provisions for H-Piles in Cohesive Soils
(American Society of Civil Engineers, 2016)Several methods are used to increase the lateral displacement capacity of the piles supporting jointless bridges, the most effective of which are predrilled holes and a flexible pile-cap connection. Depending on soil type ... -
Structural Behavior of Barges in High-Energy Collisions against Bridge Piers
(American Society of Civil Engineers, 2016)The collision of barges against bridge piers is an extreme loading condition that usually governs the design of bridges that span navigable waterways. The magnitude and time variation of impact forces depend on several ... -
Verification of the Framework for Risk-Based Bridge Inspection
(American Society of Civil Engineers, 2016)This paper presents two case studies that were conducted to evaluate the effectiveness of a new, risk-based inspection (RBI) method. The overall objectives of the case studies were to demonstrate the implementation of the ... -
