Long-Term Monitoring Strategy for Time-Dependent Deflections of Posttensioned Concrete Bridges
(American Society of Civil Engineers, 2017)A monitoring strategy for investigating the long-term longitudinal deflections at the expansion joints of the I-35W St. Anthony Falls Bridge was developed as a means of inferring the integrity of the bearings. During the ... -
Early Warning of Abnormal Train-Induced Vibrations for a Steel-Truss Arch Railway Bridge: Case Study
(American Society of Civil Engineers, 2017)Considering the new challenges for high-speed railway bridges, the early warning of abnormal train-induced vibrations is necessary for ensuring the operation safety of both the bridge structures and the trains on the bridge. ... -
Pile Response under Axial Tension Forces in Sandy Soils
(American Society of Civil Engineers, 2017)This paper presents a methodology to predict the pile-head load versus displacement curve, and the associated mobilized stiffness of a pile embedded into sandy soils, on the basis of the soil-pile interaction. The mobilized ... -
Lifecycle Decision Framework for Steel Bridge Painting
(American Society of Civil Engineers, 2017)Bridge agencies seek to apply appropriate rehabilitation or maintenance treatments at the right time. For a specific treatment, improper timing can have significant adverse consequences: Premature application could mean ... -
Evaluation of Bridge Abutments and Bounded Wall Type Structures with Ultraseismic Waveform Tomography
(American Society of Civil Engineers, 2017)A new ultraseismic waveform tomography technique for a bounded medium is presented for evaluation of concrete bridge abutments, or wall piers, and the supporting soil and rock underneath them. Ultraseismic wave fields are ... -
Fatigue Damage in Railway Steel Bridges: Approach Based on a Dynamic Train-Bridge Coupled Model
(American Society of Civil Engineers, 2017)This paper evaluates the fatigue stress and damage accumulation in steel railway bridges using a dynamic coupled train-bridge system model. The system consists of a spatial vehicle model, a three-dimensional (3D) bridge ... -
New Method for Identifying Internal Forces of Hangers Based on Form-Finding Theory of Suspension Cable
(American Society of Civil Engineers, 2017)Tensions in the hangers of suspension bridges are vital for quality control during their construction and health monitoring and maintenance during service. Hence, accurate and efficient estimation of the tensions in hangers ... -
Collapse Failure of Prestressed Concrete Continuous Rigid-Frame Bridge under Strong Earthquake Excitation: Testing and Simulation
(American Society of Civil Engineers, 2016)In recent years, increasing attention has been paid to the collapse failures of long-span continuous rigid-frame bridges under strong earthquake excitations. This paper presents the results of a study in which a 1:15 scaled ... -
Modified Steel-Jacketed Columns for Combined Blast and Seismic Retrofit of Existing Bridge Columns
(American Society of Civil Engineers, 2016)Steel jacketing has been used extensively in the United States to retrofit seismically deficient bridge columns. This procedure, which consists of encasing a RC column in a steel jacket, is effective in providing a ductile ... -
Seismic-Resistant Bridge Columns with Ultrahigh-Performance Concrete Segments
(American Society of Civil Engineers, 2016)The flexural capacity of a well-designed RC column deteriorates under extreme ground motion as a result of crushing of the core concrete and buckling of the longitudinal bars in the plastic hinge regions. Thus, it is ... -
Seismic Performance of Concrete-Encased CFST Piers: Experimental Study
(American Society of Civil Engineers, 2016)Concrete-encased concrete-filled steel tube (CFST) box members have been recently used as piers and arches in bridges owing to their high stiffness and strength. However, the seismic behavior of these members has not been ... -
Dynamic Assessment of Timber Railroad Bridges Using Displacements
(American Society of Civil Engineers, 2015)Infrastructure spending is such a large component of a railroad budget that it must be prioritized to meet the concurrent safety and line capacity requirements. Current bridge inspection and rating practices recommend ... -
Safety and Stability of Light-Rail Train Running on Multispan Bridges with Deformation
(American Society of Civil Engineers, 2016)This study investigated the safety and stability of light-rail trains that run on multispan simply supported bridges (MSSBs) and have experienced some settling and girder deformation caused by both foundation settlement ... -
Proposed Design Provisions for a Seamless Bridge System: Cases of Flexible and Jointed Pavements
(American Society of Civil Engineers, 2016)Expansion devices are one of the main causes for high maintenance costs in bridges. In this paper, a seamless bridge system is presented that results in bridges with long service lives by eliminating the joints over the ... -
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 ... -
Prestressed CFRP Strips for Concrete Bridge Girder Retrofitting: Application and Static Loading Test
