Improved Optimization Formulations for Launching Nose of Incrementally Launched Prestressed Concrete Bridges
(American Society of Civil Engineers, 2011)The conventional design process of a launching nose of an incrementally launched bridge is based on trial-and-error methods to reduce bending moment of prestressed concrete deck at the foremost support during launch. With ... -
Verification of Incremental Launching Construction Safety for the Ilsun Bridge, the World’s Longest and Widest Prestressed Concrete Box Girder with Corrugated Steel Web Section
(American Society of Civil Engineers, 2011)The Ilsun Bridge is the world’s longest (801 m in total length) and widest (30.9 m in maximum width) prestressed concrete box girder bridge incorporating a corrugated steel web. This bridge has fourteen spans, twelve of ... -
Retrofitting Short-Span Precast Channel Beam Bridges Constructed without Shear Reinforcement
(American Society of Civil Engineers, 2011)This paper investigates retrofitting precast, nonprestressed, channel beams (PCB) used in short-span bridges to improve beam shear strength and, consequently, beam ductility. Three retrofit approaches were investigated: ... -
Comparison of Ambient Vibration Response of the Runyang Suspension Bridge under Skew Winds with Time-Domain Numerical Predictions
(American Society of Civil Engineers, 2011)Existing buffeting theories and methods for dealing with skew winds are summarized. A modified version of the mean wind decomposition method is described that directly uses wind monitoring data from structural health ... -
Behavior of Structural Composite Lumber T-Beam Bridge Girders after Fatigue Loading
(American Society of Civil Engineers, 2011)Recent innovation in the engineered wood industry has produced structural composite lumber (SCL) that achieves excellent strength, stiffness, and efficient use of wood. Product variations of SCL, such as laminated veneer ... -
Method for Testing the Tension of Vertical Prestressing Bars in Webs of Concrete Box Girder Bridges
(American Society of Civil Engineers, 2011)Vertical prestress is widely used in the webs of large-span concrete box girder bridges but has lost efficacy since it was first applied. To solve this widespread problem, a dynamic model for the exposed segment of the ... -
Static and Dynamic Behavior of High- and Ultrahigh-Performance Fiber-Reinforced Concrete Precast Bridge Parapets
(American Society of Civil Engineers, 2011)New designs of precast bridge parapets made with fiber-reinforced concrete (FRC) were developed using nonlinear finite-element calculations. Specific properties of high- and ultrahigh-performance FRC were exploited in these ... -
Nonlinear Finite-Element Analysis of Posttensioned Concrete Bridge Girders
(American Society of Civil Engineers, 2011)Posttensioning is an effective method for the construction of different types of bridge girders such as those used in segmentally erected bridges. Available nonlinear analysis programs for bridge girders under severe loading ... -
Bearing and Shear Failure of Pipe-Pin Hinges Subjected to Earthquakes
(American Society of Civil Engineers, 2011)Pipe-pin rotational two-way column hinges were developed by bridge designers at the California Department of Transportation. An extensive experimental and analytical study was undertaken to understand the behavior of ... -

Nonlinear Rail-Structure Interaction Analysis of an Elevated Skewed Steel Guideway
(American Society of Civil Engineers, 2011)The use of continuous welded rail (CWR) with direct fixation of track on concrete deck is typical of most modern light-rail aerial structures. The interaction between the CWR and the elevated structure takes place through ... -
Cyclic Testing of Large-Scale Rectangular Bridge Columns under Bidirectional Earthquake Components
(American Society of Civil Engineers, 2011)Bidirectional cyclic testing was performed on four half-scale reinforced-concrete rectangular bridge column specimens to examine the need to account for bidirectional seismic loading in design for earthquakes expected in ... -
Wave Passage and Ground Motion Incoherency Effects on Seismic Response of an Extended Bridge
(American Society of Civil Engineers, 2011)This paper investigates the implications of ground motion spatial variability on the seismic response of an extended highway bridge. An existing 59-span, 2,164-meter bridge with several bearing types and irregularity ... -
Modified Yield Line Theory for Full-Depth Precast Concrete Bridge Deck Overhang Panels
(American Society of Civil Engineers, 2011)Full-depth precast deck slab cantilevers also referred to as full-depth precast concrete bridge deck overhang panels are becoming increasingly popular in concrete bridge deck construction. To date, no simple theory is able ... -
Uncertainty Analysis of Creep and Shrinkage Effects in Long-Span Continuous Rigid Frame of Sutong Bridge
(American Society of Civil Engineers, 2011)The long-term behavior of long-span prestressed concrete continuous rigid-frame bridges is significantly sensitive to creep and shrinkage. Therefore, it is important to accurately estimate creep and shrinkage effects. This ... -
Equivalent Modal Damping of Short-Span Bridges Subjected to Strong Motion
(American Society of Civil Engineers, 2011)In this paper four different methods are investigated for estimating the equivalent modal damping ratios of a short-span bridge under strong ground motion by considering the energy dissipation at the boundary. The Painter ... -
Influence of Foundation Scour on the Dynamic Response of an Existing Bridge
(American Society of Civil Engineers, 2011)Foundation scour is a major issue affecting the structural safety of existing bridges, hence its monitoring is of paramount importance. This paper reports a case history of assessment and monitoring with dynamic tests for ... -
