Influence of Inelastic Tower Links on Cable-Supported Bridge Response
(American Society of Civil Engineers, 2005)A new concept for bridge tower designs in seismic zones incorporates sacrificial link schemes that enable the tower shafts to remain elastic under large seismic excitation. In order to study the influence of inelastic tower ... -
Geometrical Nonlinearity and Length of External Tendons
(American Society of Civil Engineers, 2005)External prestressing is achieving widespread success. However, some practical rules are not yet well established. An important question deals with the maximum distance between anchorages and deviators. Due to the absence ... -
Integral Abutment-Backfill Behavior on Sand Soil—Pushover Analysis Approach
(American Society of Civil Engineers, 2005)This paper presents a study on the behavior of the abutment-backfill system under positive thermal variation in integral bridges built on sand. A structural model of a typical integral bridge is built, considering the ... -
Lateral Load Distribution in Curved Steel I-Girder Bridges
(American Society of Civil Engineers, 2005)The purpose of this paper is to develop new formulas for live load distribution in horizontally curved steel I-girder bridges. The formulas are developed by utilizing computer model results for a number of different ... -
Optimum Design of Welded Steel Plate Girder Bridges Using a Genetic Algorithm with Elitism
(American Society of Civil Engineers, 2005)The genetic algorithm (GA) is a general optimization technique that has some unique features that are especially suitable for structural engineering problems. This work uses a simple GA with elitism to find the optimum ... -
Vehicle Collision with Bridge Piers
(American Society of Civil Engineers, 2005)Inelastic transient finite element simulations are used to investigate the demands generated during collisions between vehicles and bridge piers. Such collisions have occurred in the past, sometimes with catastrophic ... -
Vibration Control of Railway Bridges under High-Speed Trains Using Multiple Tuned Mass Dampers
(American Society of Civil Engineers, 2005)In this paper, multiple tuned mass dampers (MTMDs) are considered for suppressing the vibration of railway bridges under high-speed trains. The interaction equations of motion between the vehicle and the bridge with MTMDs ... -
Impact of Posted Load Limits on Highway Bridge Reliability
(American Society of Civil Engineers, 2005)The effectiveness of posted load limits in reducing annual maximum live load effects, thus enhancing bridge reliability, is investigated for 12 and 40 m simple span highway bridges. Novel analytical expressions are derived ... -
Behavior, Analysis, and Design of an Instrumented Link Slab Bridge
(American Society of Civil Engineers, 2005)Presented in this paper are the results of a research project on the monitoring and assessment of the first link slab jointless bridge in the state of North Carolina. The structure was instrumented with a remote data ... -
Performance of Coated Reinforcing Bars in Cracked Bridge Decks
(American Society of Civil Engineers, 2005)The presence of cracks in bridge decks that are reinforced with epoxy-coated reinforcing (ECR) bars has raised some concerns among bridge and maintenance engineers in the state of Iowa. To study the effects of deck cracking ... -
Effective Bond Length of Carbon-Fiber-Reinforced Polymer Strips Bonded to Fatigued Steel Bridge I-Girders
(American Society of Civil Engineers, 2005)After years in service, many steel girders have deteriorated to the point where fatigue cracks have initiated in the girders. In girders having cover plates that do not terminate in a compression region, a common type of ... -
Effect of Edge Stiffening and Diaphragms on the Reliability of Bridge Girders
(American Society of Civil Engineers, 2005)Secondary elements such as barriers, sidewalks, and diaphragms may affect the distribution of live load to bridge girders. The objective of this study is to evaluate their effect on girder reliability if these elements are ... -
Bridge Scour and Substructure Deterioration: Case Study
(American Society of Civil Engineers, 2005)In 1988, the State of Mississippi set up its first statewide underwater bridge inspection program. During this inspection, serious damage was found on the substructure of two parallel bridges on I-10 near Biloxi. Significant ... -

Secondary Prestressing Moments in Rehabilitated Posttensioned Bridges
(American Society of Civil Engineers, 2005)Typical rehabilitation procedures for posttensioned slab bridges involve removing concrete from the top surface of the bridge, replacing corroded reinforcement, and resurfacing with new concrete. These permanently change ... -
Swaying of Pedestrian Bridges
(American Society of Civil Engineers, 2005)The paper considers nonlinear (autoparametric) resonance in footbridges as a reason for excessive lateral vibrations induced by walking pedestrians. To describe the above-mentioned phenomenon, a physical model (an elastic ... -
Dynamic Characteristics of Chilean Bridges with Seismic Protection
