Biomechanically Excited SMD Model of a Walking Pedestrian
(American Society of Civil Engineers, 2016)Through their biomechanical properties, pedestrians interact with the structures they occupy. Although this interaction has been recognized by researchers, pedestrians’ biomechanical properties have not been fully addressed. ... -
Shear Capacity of CFRP Posttensioned Grouted Transverse Joints under Concentrated Loads
(American Society of Civil Engineers, 2016)The transverse joint between full-depth precast concrete panels in accelerated bridge construction (ABC) is a critical element for satisfactory performance of bridge decks. Live loads on bridge decks are caused by concentrated ... -
Direct Integration Algorithms for Efficient Nonlinear Seismic Response of Reinforced Concrete Highway Bridges
(American Society of Civil Engineers, 2016)Reinforced concrete (RC) highway bridges are essential lifeline structures, especially in California, which has numerous active faults at which earthquakes are common occurrences. Accurate seismic structural analysis is ... -
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 ... -
Prestressing Optimization and Local Reinforcement Design for a Mixed Externally and Internally Prestressed Precast Segmental Bridge
(American Society of Civil Engineers, 2016)The precast segmental construction is advantageous for rapid erection, high quality of concrete segments, and minimal disturbance to traffic. This paper compares two different tendon layouts of a segmental bridge erected ... -
Assessing Relative Risk for the Failure Modes of a Bridge Scour Countermeasure
(American Society of Civil Engineers, 2016)Widely used failure modes and effects analysis (FMEA) can be very effective in assessing the relative risks of the failure modes of a bridge scour countermeasure. In this study, an approach is developed for assessing the ... -
Control of Human-Induced Vibrations of a Curved Cable-Stayed Bridge: Design, Implementation, and Field Validation
(American Society of Civil Engineers, 2016)This article describes the research work relating to the assessment and control of human-induced vibration of an unusual curved cable-stayed bridge with separate road and pedestrian decks. Dynamic simulations of human-induced ... -
Updating the Seismic Reliability of Existing RC Structures in a Marine Environment by Incorporating the Spatial Steel Corrosion Distribution: Application to Bridge Piers
(American Society of Civil Engineers, 2016)Although several models are available for evaluating the structural performance of corroded reinforced concrete (RC) structures, seismic reliability assessments considering the effect of steel corrosion are currently scarce. ... -
Cyclic Loading for RC Bridge Columns Considering Subduction Megathrust Earthquakes
(American Society of Civil Engineers, 2016)Current structural design philosophies rely on the inelastic capacity of structures for resisting seismic excitations. To assess such capacity, cyclic loading protocols have been used as a common practice in laboratory and ... -
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 ... -
New Bridge Forms Composed of Modular Bridge Panels
(American Society of Civil Engineers, 2016)Panelized bridge systems (e.g., Bailey, Mabey Johnson, Acrow) are intended for girder-type bridges and have been implemented for military, civilian, and disaster relief applications. Design challenges, however, include ... -
Safety of Cable-Supported Bridges during Fire Hazards
(American Society of Civil Engineers, 2016)Understanding of the performance of critical bridges, such as cable-supported bridges, during accidental fire is necessary for developing mitigation strategies against potential fire damage. In this research, the structure–fire ... -
Mode Shape Expansion for Lively Pedestrian Bridges through Kriging
(American Society of Civil Engineers, 2016)This paper investigates the use of kriging as a powerful tool for mode shape interpolation in flexible pedestrian bridges. Kriging can be used to interpolate a set of sparse mode shape coordinates obtained through experimental ... -
Longitudinal Stiffness of Multispan Suspension Bridges
(American Society of Civil Engineers, 2016)The longitudinal stiffness of multispan suspension bridges plays an important role in load-resisting systems. In this paper, a model defined as the kinematic multispring (KMS) model is proposed for simulating the longitudinal ... -
Scour Effect on Bridge and Vehicle Responses under Bridge–Vehicle–Wave Interaction
(American Society of Civil Engineers, 2016)Bridge scour is a major cause of bridge failures and has emerged as a significant concern for bridge engineers. Most studies focus on the scour mechanism, modeling, detecting and monitoring, and countermeasures. To detect ... -
Bridge Fatigue Service-Life Estimation Using Operational Strain Measurements
(American Society of Civil Engineers, 2016)Fatigue service life of steel bridges subjected to cyclic live loads was studied using operational strain measurements of a full-scale bridge. Fatigue fracture can be brittle and sudden, potentially leading to catastrophic ... -
Analyzing Prerepair and Postrepair Vibration Data from the Sarah Mildred Long Bridge after Ship Collision
(American Society of Civil Engineers, 2016)The Sarah Mildred Long Bridge, an 854-m (2,804-ft) double-deck truss bridge in Portsmouth, New Hampshire, was struck by a 144-m (473-ft) cargo ship on April 1, 2013. After days of visual inspection and assessment, it was ... -
Series of Full-Scale Field Vibration Tests and Bayesian Modal Identification of a Pedestrian Bridge
