RISImpact of Wind Load Characteristics on Computed Bridge Stay-Cable Forces Used for Bridge Health Monitoring
Publisher: ASCE
Abstract: Monitoring the magnitude of stay-cable forces over time can play a key role in assessing the integrity and safety of a cable-stayed bridge. A variety of methodologies have been proposed to estimate stay-cable forces, with ...
Analysis of Multiple‐Bay Frames Using Continuum Model
Publisher: American Society of Civil Engineers
Abstract: An approximate method that can be used to determine displacements and member forces of multiple‐bay frames is presented. The method utilizes simple continuum models. Finite‐element representations of building frameworks ...
Closure to “Dynamic Analysis of Tall Building Using Reduced‐Order Continuum Model” by Michael J. Chajes, Liyang Zhang, and James T. Kirby
Publisher: American Society of Civil Engineers
Load Distribution for a Highly Skewed Bridge: Testing and Analysis
Publisher: American Society of Civil Engineers
Abstract: The American Association of State Highway and Transportation Officials (AASHTO) specifications provide formulas for determining live load distribution factors for bridges. For load distribution factors to be accurate, the ...
Experimental Load Rating of a Posted Bridge
Publisher: American Society of Civil Engineers
Abstract: Results of an experimental load test of a posted, three-span, steel-girder-and-slab bridge are presented. The bridge was designed to have three simple supported spans, each consisting of a cross section with nine noncomposite ...
Dynamic Analysis of Tall Building Using Reduced-Order Continuum Model
Publisher: American Society of Civil Engineers
Abstract: On Oct. 17, 1989, a tall, steel-framed, San Francisco office building with 47 above-grade stories was excited by the Loma Prieta earthquake. The building response was recorded by accelerometers maintained by the California ...
Corrosion Detection of Steel Cables using Time Domain Reflectometry
Publisher: American Society of Civil Engineers
Abstract: Corrosion of steel cables and reinforcing steel in concrete structures is a major cause of structural deterioration. The current methods for corrosion detection suffer from several significant drawbacks. In this paper, a ...
Strengthening of a Steel Bridge Girder Using CFRP Plates
Publisher: American Society of Civil Engineers
Abstract: For bridge owners faced with a rising number of structurally deficient steel bridges, the rehabilitation of steel girders using advanced composite materials offers an attractive solution for short-term retrofit or long-term ...
Application of Orthotropic Thin Plate Theory to Filled Steel Grid Decks for Bridges
Publisher: American Society of Civil Engineers
Abstract: 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 ...
Determining Strain Threshold Values for Bridge Condition Assessment Using Normal Mixture Models
Publisher: ASCE
Abstract: Structural health monitoring (SHM) enables bridge owners to evaluate bridge conditions efficiently and accurately. When implementing SHM, a popular method to detect the abnormal response of a structure is statistical pattern ...
