Model Identification of an Arch Bridge for Dynamic Analysis
The dynamic responses of a steel deck tension-tied arch bridge subjected to earthquake excitations were investigated. The 189 m (620 ft) Birmingham Bridge located in Pittsburgh, PA was...
Reliability Analysis for Nonlinear Limit States
An analytical procedure, incorporating individual probability distributions of random variables, is proposed for generating moments of any arbitrary order for the nonlinear limit state...
On the Application of Conditional Integration in Structural Reliability Analysis
An accurate, and efficient computational procedure is proposed for structural reliability analysis. The suggested advanced Monte-Carlo simulation utilizes the concept of conditional integration...
Optimization of Structures Under Stochastic Loads
A method for design under multiple stochastic loads based on optimization is developed. The objective function such as cost is minimized under the constraint that the probabilities of...
Limit States Reliability Interaction in Optimum Design of Structural Systems
A multiobjective optimization approach to deal with structural reliability-based design under multiple limit states is developed. This approach resolves the limit states reliability interaction...
Structural Optimization Based on Component-Level Reliabilities
A minimum-weight optimum design procedure is proposed including the reliabilities of various elements in a structure as constraints. The reliability indices corresponding to the various...
Present and Future Developments in Steel Design Codes
Steel structures design codes with load and resistance factors (or 'partial factors') which are based on first-order probabilistic concepts are now in use in...
LRFD for Engineered Wood Construction: ASCE Pre-Standard, Wood Industry Initiative
The structural wood community in the United States is in the process of developing a reliability-based consensus Load and Resistance Factor Design (LRFD) standard for engineered wood construction....
Limit States Design in Masonry
This paper reviews some aspects of limit states design for masonry structures based primarily on experience with a new Canadian code. Steps in an advanced second order safety index analysis...
Reliability Analysis of Reinforced Concrete Structures for Serviceability Limit States
Some problems of reliability analysis of reinforced concrete structures in serviceability limit states are discussed, and two reliability analysis methods for serviceability limit states...
Analysis of Bridge Maintenance and Rating Procedures
In the United States, bridges are routinely rated to evaluate their existing conditions. The formula used to evaluate bridges is called the Sufficiency Rating Formula. The formula uses...
Seismic Reliability Analysis for Elevated Pressure Vessels
This paper presents two approaches for assessing the seismic reliability of elevated pressure vessels. A discretized mass mechanical system is used to model the dynamic effects of liquid...
Chicago's Loop: A New Approach
Reconstruction of the Wells St. Viaduct cleaned up a dangerous area just north of Chicago's Loop by providing a structurally sound approach for CTW commuter trains and a column-free...
Tales From Milwaukee's Underground
Written from RETC papers and interviews, this article is a status update on the Milwaukee Metropolitan Sewerage District's $2.1 billion Water Pollution Abatement program,...
HELP is on The Way
Hill and Davies describe current progress on the development of a Heavy Vehicle Electronic License Plate (HELP) system in the United States. The HELP system concept combines automatic...
Case Histories of Sulfide Corrosion
Section 522 of the Water Quality Act of 1987 requires the U.S. Environmental Protection Agency (EPA) to conduct a study of sulfide corrosion and control options in collection and treatment...
Investigation & Rehabilitation of Seattle's Tolt Pipeline
Seattle Water Department's Tolt Pipeline brings water 24 miles from storage in the Cascade Mountains into city and suburban distribution systems. Twenty-three miles of this...
Comprehensive Leak Detection Survey and Benefit/Cost Analysis
Fort Carson, Colorado was the site of a comprehensive leak detection investigation of the potable water system with the express purpose of quantifying the benefits to be derived by a military...
Next Stop: The Los Angeles Metro Rail
The Los Angeles Metro Rail is a $6.5 billion light and heavy rail system, which may be entirely completed by the year 2000. A 22 mi segment of the 150 mi light rail system, connecting...
Anchorage Sewer Rehabilitation in Campbell Lake
