Cable Anchorage System Modeling Methods for Self-Anchored Suspension Bridges with Steel Box Girders
(American Society of Civil Engineers, 2014)The multiscale modeling method is newly introduced to the research on cable anchorage systems for self-anchored suspension bridges with steel box girders to improve the reliability of the conventional modeling methods. Two ... -
Longitudinal Restraint of a Double-Cable Suspension Bridge
(American Society of Civil Engineers, 2014)A double-cable system has wide application prospects in multispan suspension bridges. Longitudinal restraint stiffness of a double-cable system to the tower was studied in this paper. Two formulas were derived to calculate ... -
Observer Kalman Filter Identification for Output-Only Systems Using Interactive Structural Modal Identification Toolsuite
(American Society of Civil Engineers, 2014)Several modal identification techniques have been developed in the past few decades, and their use is rapidly expanding due to new focus on the instrumentation of major structures. This paper focuses on the expansion of ... -
Simultaneous Cross Section and Launching Nose Optimization of Incrementally Launched Bridges
(American Society of Civil Engineers, 2014)The conventional design process of the launching nose of an incrementally launched bridge is usually based on parametric models with great limitations and the use of a trial and error technique to improve the design. Facing ... -
Fatigue Reliability of Hammerhead Bridge Piers
(American Society of Civil Engineers, 2014)This paper aimed to determine safety levels involved in bridge pier design when the fatigue nature of traffic load is included. Reliability analysis was used to estimate values of reliability index for the ultimate limit ... -
Experimental Research on the Effects of a Tuned Particle Damper on a Viaduct System under Seismic Loads
(American Society of Civil Engineers, 2014)This paper presents a preliminary design approach for tuned particle dampers for continuous viaducts. A series of shaking table tests of a -
Influence of Soil-Structure Interaction and Liquefaction on the Isolation Efficiency of a Typical Multispan Continuous Steel Girder Bridge
(American Society of Civil Engineers, 2014)Isolation has been identified as a popular retrofit measure for seismically deficient bridges. However, most isolation designs neglect soil-structure interaction (SSI) effects. The feasibility of isolation for bridges with ... -
Unbonded Transverse Posttensioning of a Railway Bridge in Haparanda, Sweden
(American Society of Civil Engineers, 2014)The majority of railway lines in Sweden are designed to support axle loads of up to 250 kN. Because of increased transport needs on some lines, an axle load limit of at least 300 kN would be beneficial. To upgrade the ... -
Prestress Loss of a New Vertical Prestressing Anchorage System on Concrete Box-Girder Webs
(American Society of Civil Engineers, 2014)A new, double-tensioned prestressing steel strands anchorage system (DTPSSAS), characterized by low prestress loss caused by prestressing tendon retraction, is described. When it is used for short prestressing tendons in ... -
Live Load Distribution Factors in Two-Girder Bridge Systems Using Precast Trapezoidal U-Girders
(American Society of Civil Engineers, 2014)The lever rule method is often used to determine live load distribution factors (LDFs) in two-girder bridge systems because of the ranges of applicability implicit in the simplified equations of the AASHTO LRFD bridge ... -
Shake Table Studies of Energy-Dissipating Segmental Bridge Columns
(American Society of Civil Engineers, 2014)Five one-third scale segmental bridge columns with plastic hinges incorporating different advanced materials were designed and tested on one of the shake tables at the University of Nevada, Reno. The columns were subjected ... -
Development of an Experimentally Validated Analytical Model for Modular Bridge Expansion Joint Behavior
(American Society of Civil Engineers, 2014)Modular bridge expansion joints (MBEJ) are large-capacity systems placed between two superstructure segments designed to provide safe joint crossing based on anticipated bridge movements. Locations of discontinuity in ... -
Time-Progressive Dynamic Assessment of Abrupt Cable-Breakage Events on Cable-Stayed Bridges
(American Society of Civil Engineers, 2014)Although long-span bridges are usually designed with sufficient structural redundancy, particular concerns arise about the abrupt breakage of bridge cables, which may cause progressive failure such as zipper-like collapse. ... -
Strength and Ductility of Shear Studs under Tensile Loading
(American Society of Civil Engineers, 2014)AASHTO defines fracture-critical members (FCMs) as components in tension whose failure is expected to lead to bridge collapse. Accordingly, the bottom flanges of a twin steel box-girder bridge are considered to be ... -
Nonlinear Behavior and Simulation of Concrete Columns Reinforced by Steel-FRP Composite Bars
(American Society of Civil Engineers, 2014)Steel-fiber-reinforced polymer (FRP) composite bars (SFCBs) have been proposed as a new form of reinforcement for concrete structural elements, such as bridge columns. SFCBs have high initial elastic stiffness provided by ... -
