Equivalent Wheel Load Approach for Slender Cable-Stayed Bridge Fatigue Assessment under Traffic and Wind: Feasibility Study
(American Society of Civil Engineers, 2007)In the current AASHTO LRFD specifications, the fatigue design considers only one design truck per bridge with 15% dynamic allowance. While this empirical approach may be practical for regular short and medium span bridges, ... -
AASHTO-LRFD Live Load Distribution for Beam-and-Slab Bridges: Limitations and Applicability
(American Society of Civil Engineers, 2007)This paper presents a comparison between the live load distribution factors of simple span slab-on-girders concrete bridges based on the current AASHTO-LRFD and finite-element analysis. In this comparison, the range of ... -
Routing and Permitting Techniques of Overweight Vehicles
(American Society of Civil Engineers, 2007)Overweight vehicles require permits to cross the highway bridges, which are designed for “design load vehicles” (prescribed in the national standards). A new, fast, and robust method is presented for the verification of ... -
Application of Orthotropic Thin Plate Theory to Filled Steel Grid Decks for Bridges
(American Society of Civil Engineers, 2007)Although AASHTO LRFD specifications provide moment capacity equations as an approximate design method and recommend an orthotropic plate model as the refined method for the analysis of filled grid decks, no guidelines are ... -
Comparative Probabilistic Initial Bridge Load Rating Model
(American Society of Civil Engineers, 2007)A model that applies to initial bridge load ratings based on allowable stress, load factor, and load and resistance factor design is presented. The prognostic component calculates bridge load ratings probabilistically ... -
Structural Behavior of Short Span Precast Channel Beam Bridges without Shear Reinforcement
(American Society of Civil Engineers, 2007)This paper presents findings of a research study conducted by the writers for the Arkansas State Highway and Transportation Department. The study investigated precast nonprestressed concrete channel beam sections cast ... -
Discussion of “Consistent Approach to Calculating Stresses for Fatigue Design of Welded Rib-to-Web Connections in Steel Orthotropic Bridge Decks” by Robert J. Connor and John W. Fisher
(American Society of Civil Engineers, 2007) -
Nonlinear Finite-Element Analysis of Reinforced Concrete Bridge Approach Slab
(American Society of Civil Engineers, 2007)A bridge approach slab serves as a structural slab between the bridge structure and the approach embankment. The primary causes of approach slab failures are undermining, settlement and cracking. Undermining and settlement ... -
Challenges in the Application of Stochastic Modal Identification Methods to a Cable-Stayed Bridge
(American Society of Civil Engineers, 2007)This paper presents an analysis of the data collected in the ambient vibration test of the International Guadiana cable-stayed Bridge, which links Portugal and Spain, based on different output-only identification techniques: ... -
Autoparametric Resonance in a Pedestrian Steel Arch Bridge: Solferino Bridge, Paris
(American Society of Civil Engineers, 2007)Autoparametric resonance is treated as the reason of arising excessive lateral vibrations in the steel arch bridge (the Solferino Bridge). To explain this phenomenon, a physical model (a double pendulum) is proposed. Its ... -
Concrete Cracking in Tension Members and Application to Deck Slabs of Bridges
(American Society of Civil Engineers, 2007)Currently, estimations of the crack width in the deck slab of bridges given by codes of practice are based on either theoretical or empirical approaches considering mainly the monotonic loading behavior. However, cracking ... -
Live Load Radial Moment Distribution for Horizontally Curved Bridges
(American Society of Civil Engineers, 2007)The present study is designed to determine the effect of major parameters on maximum total bending moments of curved girders, establish the relationship between key parameters and girder distribution factors (GDFs), and ... -
Seismic Fragility of Continuous Steel Highway Bridges in New York State
(American Society of Civil Engineers, 2007)This paper presents the results of an analytical seismic fragility analysis of a typical steel highway bridge in New York State. The structural type and topological layout of this multispan I-girder bridge have been ... -
Comparison between Shape Memory Alloy Seismic Restrainers and Other Bridge Retrofit Devices
(American Society of Civil Engineers, 2007)Strong earthquakes can result in large longitudinal displacements in multiple-frame bridges. This could lead to excessive displacements/openings at the intermediate joints. Bridges with small seat widths are vulnerable to ... -
Lateral Walking-Induced Forces on Footbridges
(American Society of Civil Engineers, 2007)In the last several years many cases of large amplitude horizontal vibrations of footbridges have been observed, due to dynamic interaction between the walkers and the footbridge, which may occur when some conditions on ... -
Tanaro Bridge: Dynamic Tests on a Couple of Spans
(American Society of Civil Engineers, 2007)The Tanaro Bridge, an 18-span -
Implications of Design Assumptions on Capacity Estimates and Demand Predictions of Multispan Curved Bridges
(American Society of Civil Engineers, 2007)The paper presents a detailed seismic performance assessment of a complex bridge designed as a reference application of modern codes for the Federal Highway Administration. The assessment utilizes state-of-the-art assessment ... -
Fatigue Behavior and Retrofit Investigation of Distortion-Induced Web Gap Cracking1
(American Society of Civil Engineers, 2007)This paper studies a Kansas Department of Transportation welded plate girder bridge that developed fatigue cracks at small web gaps close to the girder top flange. Repair had been previously performed by softening the ... -
Crack Condition Evaluation Approach for the Deteriorated Girder of an RC Bridge
(American Society of Civil Engineers, 2007)A crack condition evaluation method is proposed that identifies the damaged state of deteriorated reinforced concrete (RC) girders on bridges directly on-site. This nondestructive testing approach is based on stress wave ... -
Seismic Performance Assessment of Simply Supported and Continuous Multispan Concrete Girder Highway Bridges
(American Society of Civil Engineers, 2007)Seismic evaluations of typical concrete girder bridges are conducted for both a multispan simply supported and a multispan continuous girder bridge common to the Central and Southeastern United States. These evaluations ...
