Fatigue Life Evaluation of Welded Structural Details in Steel Highway Bridge
Stresses in highway bridge members, fatigue crack propagation behavior and long life fatigue strength properties of welded members under traffic loadings and prediction of fatigue life...

Evaluation of Bridge Safety and Remaining Life
In developed countries, the emphasis on the infrastructure is changing from new construction to the safe maintenance of existing structures. Highway bridges represent an excellent example...

Study and Design of Multi-Span Continuous Bridge
Multi-span continuous bridges which have been constructed in the Metropolitan Expressway Public Corporation are briefly explained. Some studies were carried out into their behavior. The...

Load and Resistance Factor Design for Engineered Wood Construction
The wood industry has provided sponsorship for the development of a reliability-based, load and resistance factor design specification for engineered wood structures. This user-tested,...

Load Combinations for LRFD With Wood Construction
Probability based limit states design for wood construction is complicated by the fact that wood is a natural material with large variations in mechanical properties and is sensitive to...

LRFD for Engineered Wood Construction: Calibration to Current Design
The structural design code for engineered wood construction is evolving to a limit state design basis in which the safety checks are derived from the underlying probability distributions...

Member Design Equations for a LRFD Wood Specification
A key step in the preparation of a load and resistance factor design (LRFD) based design specification for engineered wood construction is the selection of the behavioral equations for...

LRFD: Progress for Engineers and the Wood Industry
The LRFD for Wood project represents a milestone for the industry. The significance of the project goes far beyond merely switching formats in design equations. The project signifies both...

Reliability Models for Bridge Structures
The development of rational design criteria requires efficient measures of structural performance. Traditional methods of analysis do not reveal the actual safety reserve (degree of redundancy)....

Inelastic Earthquake-Resistant Design of Bridges?Application to Concrete Cable-Stayed Bridges
Various methods of earthquake-resistant design of bridges use in both the U.S. and Japan are summarized and reviewed. Among them, principles of approximate and rigorous inelastic earthquake...

Seismic Design of Cable-Stayed Bridges: Evaluation and Research Needs
Earthquake-response characteristics of cable-stayed bridge are evaluated. 2-D and 3-D models are considered. The cases of multiple-support and uniform excitations are considered; furthermore,...

Current Bridge Research at Iowa State University
For the past 20 years the majority of the structural engineering faculty in the Department of Civil and Construction Engineering at Iowa State University (ISU) have performed research...

Some Design Considerations During Construction
Certain construction failures are discussed with associated design conditions leading to these failures. Some points of interest for engineers involved with construction equipment designs...

Heath Building?Load Paths of an Underpinning
A case study of an underpinning is presented which, in principle, consists of the introduction of a transfer system in an existing building. The transfer system modifies the load paths...

Codified Reliability for Structures During Construction
It is generally acknowledged that the most critical stage of a structure's lifetime is that of construction, leading to failures or locking in forces and deformations that...

Standards for Design Loads During Construction: An ASCE Effort
ASCE embarked on a new standards activity by the Design Loads for Structures During Construction Standards Committee. The objective of the effort is the development of standard guidelines...

An Overview of the U.S. Coordinated Program for Masonry Building Research
The U.S. Coordinated Program for Masonry Building Research is a time-phased set of specific research tasks addressing materials, component and system behavior. The objective of the program...

Influence of Nonlinear Models on Dynamic Displacements
This research is a part of an ongoing multi-year program that is sponsored by the National Science Foundation and conducted under the TCCMAR (Technical Coordinating Committee for Masonry...

Durability Design for Concrete Bridge Structures
The concept of durability design for concrete structures including bridge structures is proposed on the basis of comprehensive evaluation of materials, design details and construction...

Dynamic Response Prediction for Earthquake Resistance Design of Bridge Structures
Newly developed nonlinear analysis procedures for assessing the earthquake resistance of bridges have been incorporated into the computer program SEISAB (SEISmic Analysis of Bridges)....
